I had one of these crossfires in the shop. It was an auction car that a used car lot I do work for bought because it had oxygen sensor slow response codes for all four sensors and nobody including a couple of dealerships and multiple shops could find the problem. Turns out someone had the exhaust off of the car at some point while working on it and that end of the harness was symmetrical and the oxygen sensor connectors were the same. All it needed was to have the harness under the car to the oxygen sensor unplugged and flipped around and the problem was solved. 😂 The car was in great shape it just kept being shuffled around through car lots and the auction because nobody could get the light off. Needless to say he was ecstatic and threw me an extra little bonus on that job. People tend to get in their own heads when messing with Mercedes and other German cars
I had this happen on my 06 SL500. Luckily i parked it at my house then 10 minutes later it just cranked but never started. I googled the symptoms and about 20 forums popped up saying crank shaft position sensor. Took about 10 minutes and $38 to replace and old one was very oily. Cranked car and started right up. Car only had 74k miles on it. This brought back memories. I like your videos, your a very smart guy.
Dude you are very detailed love it!!!!!! Same exact with my Crossfire and I'm suspecting CAM/Crank sensor issue is using OEM or other aftermarket it seems like the HONDA scenario like the O2 sensors they like only certain manufacturers....blah, blah , blah good job on video for sure
Thanks for sharing your work Ivan. I agree with you 100% on trying to be careful not to accidentally “fix” the problem by moving stuff around. Especially with an intermittent problem. In the semi truck field, we have so many trucks that come in with intermittent electrical issues, so when the problem is finally active, you have to be very gentle with the truck to pin point the problem, other wise, it will come back. It upsets me when I see mechanics going around unplugging connectors to check the terminals prior to checking voltages, signals, etc.. Also wanted to mention that on the Navistar engines, for whatever reason, cam and cranks sensor failures hardly ever log faults. No active or previously active faults logged. Pretty strange
I think with all the wiring damage, I would have checked to make sure those wires to the sensor weren't shorting to ground, not just to each other. I have also seen sensor wires short to other wires in the harness before. When I get that far into one, and I really have a feeling that is what is going on, sometimes it is time for the snippy snippy and then bypass. I guess I would also try to let it cool then read the CKP unplugged and see if you get more than 1 volt peak to peak. I would also be curious to see if you could fire the ignition from bidirectional controls like you can on other Chryslers, or if that PCM is truly a Mercedes PCM and doesn't have the option. It isn't really needed since you had no injector pulse though, but I would be curious.
Ivan...cheers to you. Im going on the road to tomorrow. To save my grand daughter. 3k to fix her car. Got my tools. Clothes packed and parts all in a big box. Wish me luck. Its a 12 hour drive to my destination. Have a super fun day
With a crossfire it's one of three things either the RCM relay control module (you have to resolder three little pins at the bottom), the crank position sensor in the front engine, or the position sensor in the rear of the motor not impossible to get to it's just a tight fit. So many crossfires went prematurely to the junkyard, for some very simple issues. All of them in 2023 are easily corrected. If you have any Crossfire SLK related questions please feel free to ask me. I'll do my best to answer everything promptly and intelligently.
I have one in my bay right now with an airbag light on. Can’t communicate with the airbag module. Any tips or tricks? I just read about trying to scan it as an SLK, so I’m gonna try that Monday.
I had occasionally stall / no restart, shuts off completely on T190 BOBCAT skid steer loader, like some one just disconnected main power or ground at the battery. Found almost broken (rubbed) constant 12V feed wire to the cab key ignition switch. Thanks Ivan, great video as usual. Waiting for part 2. Cheers!
Thank you for explaining your thoughts and actions to avoid. Probably never work on a Benz powered Chrysler, but applying your techniques will help avoid the parts cannon on a hybrid's climate control system later this week.
I've had a similar issues on a diesel LDV V80, it would crank no start. Only DTC was for CKP signal disturbed. Scoped it, new sensor, wires load tested, target wheel all fine. It turned out to be starter motor failing, drawing too much current and there wasn't enough for CKP sensor. New starter fixed it. But it cranked fine you would not tell that starter was faulty
I've worked on a number of those crossfires and for some odd reason, it will almost never record a CKP sensor code. Even when it's unplugged. Something strange about Chryslers software on those ECM's. Maybe check to see if there is a TSB on a possible software update? But very common failure on those engines is a bad CKP sensor. Spot on diagnostics though.
@@annathemaanderson4448 The wiring harness gets old , I'm not sure of the actual cause but the fix is a harness and I do believe the Solenoid assembly in the ATX. I'm sure there is a TSB. The fix is easy and relatively cheap. The same happens to the Benz model cant remember the class but is set up identical.
Seems like that car was based on the Mercedes-Benz CLK. I am wanting to say that there was a CKL Kompressor that was a turbo model and the Crossfire had a turbo model as well. My neighbor had one; he didn't have it long until he got rid of it. Great video!
Great diagnostic procedure, confirming the gut feeling it was a broken CKP sensor. Wouldn't be possible without the scope and the brain controlling it :-) Very curious about the parasitic draw.
I have a 2004 crossfire. Had a issue with the battery cable. Wire going into battery clamp was lose. Being held on only by the rubber casing. Symptoms: All power was fine. Acted up when I went to start car. Lost power, headlights(main sign). Looking at cable You could not tell it was bad. Figured out by grabbing cable and it felt like cable was not secure. Cut rubber lose and cable fell out of battery clamp.
The RCM module is also known to fail, usually the PCM relay. But, I actually loss communication to the TCM relay of the RCM which did not allow the car to crank or shift out of park. The relay would click but not allow voltage across it. After applying voltage to the wires that supply the TCM the car would start and shift. FYI, with these cars some scanners will only see them if you manually look of a 2004 Mercedes’ SLK 320 16 pin. These are a diagnostic challenge!
Crank Sensors giving up when hot is a super common issues on 90s and 2000s Mercedes. Happens on every Gas Mercedes engine from a 4 cylinder to a supercharged v8 (never worked on a V12 lol).
I'm pretty sure it's a coil thing. when ignition coils on small engines start to go; they work fine untill the engine warms up. I've also seen it a couple times on fuel shutoff solenoids. engine gets to op temp and the solenoid goes open.
I've learned that after all these years, early 2000's cars the sensors start going bad. 9 time out of 10, crank and no-start/rough-start, it's crank/cam sensors. Rough idle with no code? New sparks and cleaning the MAF sensor aren't a bad place to start. People often overthink things, with a little digging and some basic DIY knowledge, you can usually fix it yourself at very low cost
Wow I would hate to see how much actual damage is done to all about wiring and it makes no sense that it did not set a crank position sensor code thank you for the video love it
Wow, Ivan the guy throwing all the wires all over and test, test and say don't trust scanner. Do scope!! Eurotrash car lol. Haha. Nice job trying to find the problem! I think when replacing the sensor and find the parasitic draw and the car will be fixed. Nice work and video!! Many thumbs up 👍 👌
I never trust my scanner. You might as well go to the Parts store Technicians and have them scan your codes and give you a Handy printed sheet. Tell you they diagnosis your car and the code says. You have a throttle body that is icing up at the middle of summer. Trust your scanner 😅😂
Had a Taurus that died a few times. First time we like an EMP hit it. Clock light even went out. Jump started and worked fine. Randomly did it a few more times. Battery a little less dead each time until it quit doing it. New battery and alternator didn’t seem to matter. Never figured it out. Fixed it self. Haunted!
kind of ridiculous the shop didnt find that mouse nest while diagnosing an alternator. It seems this issue u found is common for dodge/chrysler. a friends 2003 dodge truck had this exact same issue except he could drive it for 30minutes before it died and have to wait for it to cool down. no codes were set. a shop replaced his fuel pump twice... I came in saw his distributor was totally burnt up figured it was that even though it made no sense and after seeing it happen I said crank sensor. that fixed it.
I had a 99 Jeep Grand Cherokee. And apparently people online were saying that it will trip the same code, whether it's a bad crank or bad cam sensor... I had an intermittent CRK, and finally a bad cam sensor died. So I swapped out the cam sensor, it would run-- and then the CRK kept acting up at random and it took me a few times of it leaving me stranded to finally get it nailed down, that it was the crank sensor. I could reposition the crank sensor and it would work fine for a bit.. I think I even tried a shim, it was real finicky to get it in the right place to work correctly. But the new one worked right away, so maybe it was just too weak. So mine literally needed both. (mainly the cam sensor was bad because the guy before me kept messing with the timing, had the wires rigged and ripped out/ I had to order a new connector that fits the cam sensor and rewire it; and he even had the timing off by a tooth, which I also fixed). It was the 4.0L -- was a great motor after I got it dialed in. But getting that figured out was annoying.
On the scope, that didn't look like a crank signal to me-- it just looked like electrical noise the harness was picking up. I'm not an auto mechanic, but I'd expect the crank sensor signal to look somewhat similar, perhaps, to the crank sensor signal, a clear digital signal. And I'm stunned that disconnecting the crank sensor set no DTC code at all (and that there was no code for it at the beginning, either). Whisky Tango Foxtrot?
I always found it interesting that a lot of Mercedes will set a ckp related code for slow cranking but not a flat out failed sensor. The lack of tach reading during no start is a big red flag for me as to a diagnostic direction .
As soon as you unhooked the crank sensor and the computer still didn't trip a code, I immediately think it was a computer issue, and needs powers and grounds checked there. Because something isn't adding up -- it should KNOW that the crank sensor is gone, even if there were a short or open in the wires; unless it's shorted to another sensor wire and tricking the computer somehow. So that's odd. I like the suspense on this one though. lol..
I had one for three months and the same problem I got rid of it best solution. They were renting out the majority of cars are on my enterprise they never change the oil filter
Hey Ivan, when you use the leads to scope - like at 14:21 are you puncturing the insulation or is the reading coming through the insulation? and are those leads wireless?
I would replace the battery with a new charged battery, but only connect during the CNK sensor replacement test. If the car starts and runs without stalling after achieving operating temperature, then I would have the shop disconnect the battery, and then charge the battery disconnected, so when you arrive you will have a charged battery to diagnose parasitic draw as a starting point.
Привет, Иван! Сколько времени, ты уже пользуешься сканером ProS ? Наверное, уже кончилось время бесплатных обновлений? Что знаешь, об обновлении после 2 бесплатных лет, или в ваших краях, не 2 года?
If the wires were shorted to something else, then reconnecting the sensor to the computer without disconnecting the computer side from the harness could bring down the signal. I wonder if there is a less destructive, easy way to test for this than cutting the wires on the computer side? This seems important to test for given the known mouse problem here.
Thank you for keeping this calm where us men could understand it. Could be the stroke I had, but two sentences into that last thing you wrote fried something up there.
no reason not to scope the wires at the sensor with the sensor unplugged since he's right there. then unplug the computer connection. also that scope should have a 1 khz test signal built in. you could unplug the computer and inject that in to each wire and check if the signal is different at the other end.
One of my customers just paid 1400 for a new rcm in his crossfire. I told him if he'd let me know he was bringing it to a dishonest shop first i could have resoldiered the joint for 250. Oh well live and learn for that guy. The shop he brought it too gave him every excuse in the book and had the car for a month.
could that parasitic draw be why they replaced the alternator,the theory being that draw would put extra work on alternator everyday the cars started especially when not started for days? my gf truck just went through two alternators both 3 months apart,i found 130ma draw from a fuse that was in a non designated spot that was keeping a relay on with key off,but after removing this fuse the draw went down to 12ma and no more alternators burning up i suspect the draw was the issue.
Is it me, or are Chrysler products just electrical nightmares waiting to happen? I follow several blogs (automotive repair , off road,, and some Jeeps) and Chryslers grab the lion's share of electrical issues. I know my '98 TJ is prone to go wacky if I add something it doesn't like ( even OEM sensors can act up) but it seems like the newer stuff is even more problematic.
The problem diagnosed here is common to the R170 Mercedes Benz SLK 320 that this car is based on. The Chrysler part is the suspension tuning and body style.
@@cwilsonpa Excellent point! And from what I gather the best solution is to replace the sensor with that specific to the Mercedes 320SLK and not the Chrysler Crossfire version (technical blogs seem to verify that the Chrysler unit is prone to fail also). Go figure....
To be honest, you could see all sorts of problems from that wiring damage. Even if you fix it now, would you want to drive more than a mile or two from home ?
Happen on mu crdi JM tucson as well, crank sensor failed and the ecu didn't throw any codes.. You would think it would be easy to determine if the crank sensor was missing if the ecu got a cam signal but no ckp.
The problem at the start of of the video was no electrical activity at all, no horn, no lights, no crank. When you were diagnosing the car, you had crank, no start. These sound like quite different issues.
i had this one car it was toyota highlander same thing when it get warm up it will stall costumer wait 30 mints and starts the car and car will start however the pcm set a cam crank code and then i got direction connect my scope and move the wire crank signal got messed up and stall it was some shop put the alternator and chew the wire for crank sensor and problem was fixed
Ive only watched a few mins of this but i had exact same issues with mine . The r.c.m has weak solider points . The 1 ground at the battery is also crap. Add a ground to the block and send your r.c.m to the crossfire dude in Florida or solider them yourself . Mine has had zero issues sense i sent my rcm off
I do not miss these Cars at all. Mercedes and Chrysler's worst combined effort. Nobody will program them anymore, not even the dealer, so they started bringing them to us. Smh. Makes me sad spending hours to do something that should take 20 minutes on any "normal" vehicle. They had a great idea to make vegetable based wire coatings. Ugh.
Story of my life! 10 Minutes of Fun...then STALLS!

You might as well explode at that point.

I have to confess it would take me a hell of a lot of self discipline to not just yeet that nest first.
Great way to showcase how to follow instincts but still remain solid in your diagnostic method.

@@PineHollowAutoDiagnostics 8-10V. Most of the time it was 9 and some change. The CKP is rather big thing with permanent magnet in it. 2 wire

Wow owner needs to invest in a cat.
Owner doesn't want the cat to be caught in the Crossfire 😅
I work exclusively on Jeeps and rarely (less than 1 in 100) see a crankshaft position sensor code when the sensor goes bad

Super common on those Mercedes V6 engines. I've replaced two of those recently. Both stopped working after ~10 minutes of running.

@@TreyCook21 Scotty would say the Chrysler is a money pit...trade it on a Toyota!
@@PineHollowAutoDiagnostics Scotty's right. But my fleet of 20+ year old Toyotas is no slouch in the money pit department either 😂
Hey Ivan, when you use the leads to scope - like at 14:21 are you puncturing the insulation or is the reading coming through the insulation? and are those leads wireless?
I would replace the battery with a new charged battery, but only connect during the CNK sensor replacement test. If the car starts and runs without stalling after achieving operating temperature, then I would have the shop disconnect the battery, and then charge the battery disconnected, so when you arrive you will have a charged battery to diagnose parasitic draw as a starting point.
So you have the best of BOTH worlds Chrysler and Mercedes JUNK in one vehicle!
Does it have a Mercedes doppelgänger? If so, do you think the scanner would tell you more if you selected that vehicle?
Привет, Иван! Сколько времени, ты уже пользуешься сканером ProS ? Наверное, уже кончилось время бесплатных обновлений? Что знаешь, об обновлении после 2 бесплатных лет, или в ваших краях, не 2 года?
Yay! Another Ivan video!
If the wires were shorted to something else, then reconnecting the sensor to the computer without disconnecting the computer side from the harness could bring down the signal. I wonder if there is a less destructive, easy way to test for this than cutting the wires on the computer side? This seems important to test for given the known mouse problem here.
Thank you for keeping this calm where us men could understand it. Could be the stroke I had, but two sentences into that last thing you wrote fried something up there.
no reason not to scope the wires at the sensor with the sensor unplugged since he's right there. then unplug the computer connection. also that scope should have a 1 khz test signal built in. you could unplug the computer and inject that in to each wire and check if the signal is different at the other end.
I think he rules out a wiring short when he went checked at the crank sensor.
In crossfires these symptoms are usually the cps or bad solder joints in the rcm.
One of my customers just paid 1400 for a new rcm in his crossfire. I told him if he'd let me know he was bringing it to a dishonest shop first i could have resoldiered the joint for 250. Oh well live and learn for that guy. The shop he brought it too gave him every excuse in the book and had the car for a month.
could that parasitic draw be why they replaced the alternator,the theory being that draw would put extra work on alternator everyday the cars started especially when not started for days? my gf truck just went through two alternators both 3 months apart,i found 130ma draw from a fuse that was in a non designated spot that was keeping a relay on with key off,but after removing this fuse the draw went down to 12ma and no more alternators burning up i suspect the draw was the issue.
Yup especially with junk aftermarket alternators lol
Is it me, or are Chrysler products just electrical nightmares waiting to happen? I follow several blogs (automotive repair , off road,, and some Jeeps) and Chryslers grab the lion's share of electrical issues. I know my '98 TJ is prone to go wacky if I add something it doesn't like ( even OEM sensors can act up) but it seems like the newer stuff is even more problematic.
The problem diagnosed here is common to the R170 Mercedes Benz SLK 320 that this car is based on. The Chrysler part is the suspension tuning and body style.
@@cwilsonpa Excellent point! And from what I gather the best solution is to replace the sensor with that specific to the Mercedes 320SLK and not the Chrysler Crossfire version (technical blogs seem to verify that the Chrysler unit is prone to fail also). Go figure....
To be honest, you could see all sorts of problems from that wiring damage. Even if you fix it now, would you want to drive more than a mile or two from home ?
Happen on mu crdi JM tucson as well, crank sensor failed and the ecu didn't throw any codes.. You would think it would be easy to determine if the crank sensor was missing if the ecu got a cam signal but no ckp.
Looks like a crank sensor failure. Goes for a short interval and voila ! Shuts down. Happened to my daughter's Civic and was unpredictable.
Great content Ivan.
Fun to work on the car :)
Excellent video thnx for sharing
YIKES!! There's a bunch of really knowledgable folks making comments here. It's quite dazzling. Can't live without the scope!
I have seen variable reluctance sensors fail before, but usually it was a prototype. Also, they failed "hard".
Great diag Ivan
Problem child? Looks like they have a parking lot full of problem children.
Good video master 😄
You are a rockstar
The problem at the start of of the video was no electrical activity at all, no horn, no lights, no crank. When you were diagnosing the car, you had crank, no start. These sound like quite different issues.
i had this one car it was toyota highlander same thing when it get warm up it will stall costumer wait 30 mints and starts the car and car will start however the pcm set a cam crank code and then i got direction connect my scope and move the wire crank signal got messed up and stall it was some shop put the alternator and chew the wire for crank sensor and problem was fixed
The rodents were enjoying the buffet.
Ive only watched a few mins of this but i had exact same issues with mine . The r.c.m has weak solider points . The 1 ground at the battery is also crap. Add a ground to the block and send your r.c.m to the crossfire dude in Florida or solider them yourself . Mine has had zero issues sense i sent my rcm off
What is the RCM?
crossfire and the M-B SLK are direct related
This is the same engine I'm dealing with the in my CLK 320.
It's driving me insane.
Seem to recall an issue with soy based license plates. Critters were eating them...
Hello good video I would like to know what brand is your red scanner that you are using on this video.
SEE DESCRIPTION
WHY DIDNT THE OTHER SHOP CLEAN OUT THE MOUSE NEST ??
I do not miss these Cars at all. Mercedes and Chrysler's worst combined effort. Nobody will program them anymore, not even the dealer, so they started bringing them to us. Smh. Makes me sad spending hours to do something that should take 20 minutes on any "normal" vehicle.
They had a great idea to make vegetable based wire coatings. Ugh.
My 2005 Caravan never sets a code when a cam or crank sensor fails. I check with my "scope on a rope" to find the issue. (crank once, cam 3 times.)
Every Mercedes I owned crank position sensor is a very know common problem
How can you measure charging amps between the battery negative and ground, is that what I just seen cool
You can measure around + or - cable...doesn't make a difference, whichever is easier to grab with the clamp :)
It's an SLK320
should have named em Chiseler crosswired....LOL
