The parts Cannon. It's a term we use for a variety of reasons in the automotive industry. mainly for hacks and bad mechanics. Even people who aren't mechanics Coffee and project fund: www.gofundme.c...
Some times, you need to dual wield the parts cannon just to get the vehicle to a level where it'll pass tech inspection. Mostly with people who buy multi-owner 15-20 year old luxury cars that have not been maintained. "What do you mean fixing my top spec 20 year old BMW 7 class will cost 9000 dollars, the car only cost 1500!"
@@H33t3Speaks i dont know how many times i've had to tell people that even tho their old luxury car was cheap, maintenance and repairs are still luxury priced 😅 How about 16 expensive spark plugs for your old mercedes sir 🙈
I’m an AG and Heavy Truck mechanic, I don’t work on ATVs unless mine or family members. The troubleshooting info in the service manual says to read the fault codes to diagnose the problem, there is no active codes. Then the service manual says which component could be causing the problem and its solution:”Replace Component”. It doesn’t give any info on how to test the components. No choice but replace parts that could be causing the issues. I’m super grateful for the crew I work with, we can brainstorm of each other. Thanks for the videos Lance! Take care!
Ya I'm in the heavy truck and I'm still asking for advice from the other guys. I'm not the smartest quickest guy and after 30 years I have no problem asking for help or advice. Some guys will kick the tires for 8 hours because they don't want to admit they don't know. That's definitely not me. Never was never will be 👍🇨🇦🔧
Its also no longer possible to swap part from other car for test purpose.Lot of parts are coded to a car and wont work with other. Cars are definitely bacame disposable items.
Owned a vw shop for several years. … Tried to tell people- buying a car with a $7000 trans coded to your vin number is insane. ‘You’re bitter’ they said. Nah I just seen a $7000 transmission should be able to hold 800HP All day Not grenade at 150hp They still say oh yea you’re just grumpy old mechanic. I ask em how much it costs to get power from engine to tires. $7k trans 1k ecu 900 in oem axles. We’re over 10k before we even factor in the engine or the body😂 But they kept taking out loans and buying new anyway. I closed my tdi shop years ago after dieselgate. Most customers are beyond hope and the only way to instill true understanding is to spend your life trying to keep thousands of cars going down the road. What do I drive? 1981 vw rabbit pickup with a tdi swap. Using a supercharged corrado trans that I got used 20 years ago for $500. That’s original from 1990 and never had so much as a hiccup
Some people use the code reader as a magic 8 ball. We as technicians use it for diagnostic purposes only and for critical thinking for data aids to see underlying problems and current. Videos are spot on
Had a similar thing in the computer repair world when the first ethernet networks got installed. Incredibly complicated, you could have a failure node on the network way off in the back of another building someplace, causing the problem at the pc I was looking at in their front office. Same thing, it took years of experience, and special diagnostic equipment, Time Domain Reflectometers, to find cable breaks and such. Sometimes all it took was a single missing cable terminator under the false floor in the computer room to goof up the whole thing. I only saw maybe a couple of guys, support level engineers, at it long enough at that time to get really good at it.
It's frustrating in many ways. Ive had customers that had worked done, by techs who got in over their heads. They felt they got screwed, and now I have to diagnosis it for pennys on the dollar? No way. My time isn't free, and I know what im doing. Also, we have all been down the road of installing brand new bad parts. I went through 3 bad BCM modules, before I got one that worked. It only took me one month, and my mental health to rip the entire H3 apart until I could figure it out. I was a young tech at the time, so it was " dumb kid doesn't know what he's doing". I had engineering on the phone with me on a daily basis. No wonder i went bald early in life.
Lance what you said is true. It happens to the best. Every mechanic at one time or another has gone down "the garden path". Also I might mention is that certain manufacturers in their troubleshooting steps my suggest/recommend that you "replace with a known good part" and if that corrects the concern then replace that part. I've worked with techs who had a small stockpile of various components under their bench or in their toolbox. I personally did as well (not alot), mainly for a way to kind of speed up the diag process. Sometimes you have to do what you have do.
Even the top tier diagnostic techs are not above replacing a part once in a while just to rule it out as a known good, especially when testing it would cost more than replacing it. I once had a 2014 ford truck with a 6.2 engine, they’re notorious for shorted ignition coils. This one had shorted coils arcing against the cylinder head and the knock sensor was triggered by the arcing and setting a DTC that in the shop manual had no diagnostic flow chart or information besides “clear codes and if it resets, replace the PCM”. Sometimes parts canon is the only option even by auto manufacturer testing methods.
I recently had a 2017 Corolla iM come in for a check engine light. Scanned it and found P0171 system lean. Like you said there are 101 things that can cause that code. Checked for TSBs, found none. Looked up service information and ran a couple tests that were suggested including an injector volume test which passed. Visually inspected everything under the hood and finally found the vacuum line going from the throttle body to the purge valve was cracked where it plugged into the throttle body. Obviously a leaking vacuum line can cause a lean condition so I ordered a replacement line. A couple days later the line came in and I replaced it. Cleared the code, test drove the vehicle in check mode and everything seemed fine. As I pulled the vehicle into the car wash (I work at a Toyota dealership) it started to idle rough and the light came on. Crap. Pulled it back into my bay and scanned it again. The lean code was back, but now it also had multiple misfire codes too. Performed the injector volume test again. This time there was no change in the bank 1 sensor 1 AF sensor voltage, when it had been responsive the first time. Service information explicitly said if there was no voltage change when running that test the sensor could be going bad. Ordered the sensor which came in the next day. Replaced it, put the vehicle in check mode, and drove it about 10 miles. The light stayed out and the vehicle ran fine. Returned the vehicle to the customer and thought that was the end of it. A few days later the car came back with the light on again. Crap. Scanned it and found the lean code was back, but now it also had several evap codes for purge flow and gross leak. The misfire codes had not returned. Checked the purge valve and found it stuck open. Ordered a purge valve which came in the next day. Replaced it, put the vehicle in check mode and drove it over 20 miles. The light stayed out and it ran fine. That was several weeks ago and it hasn't come back, so hopefully it's fixed for good. I'd say this was a case of the vehicle having several problems at once. The vacuum line was cracked and had a poor fit to the throttle body. The AF sensor voltage was flat when I checked it the 2nd time. And yes, the purge valve was sticking intermittently. While this iM wasn't super old, it did have 225k miles on it. I had also replaced the belt tensioner the first time it came in, because that was falling apart as well and making horrible noises. While Toyotas are pretty well made and reliable, once you get over 200k miles you will start seeing failures of various things.
Had a 2007 gm 1.6 16v engine with no start and zero codes. These have no mass air flow sensors. The most common problem with these are stuck throttle bodies that loose calibration. 9 times out of 10 you just clean the tb and calibrate it. On this one the calibration option was missing so we did a caveman reset by leaving the battery disconnected overnight. The next day the car started just fine but it will not rev past 1.5k rpm and it sputters like it has launch control. If you slamm the throttle the engine smoothly shuts of like its done intentionally and will not start. Finally we get a running lean fault code wich doesn't help at all. Checked fuel pressure, did an inlet smoke test, every thing looks normal. Then we installed a new tb, map sensor and nothing changed. After that we started to pull out random sensors without any luck. In the end whe pulled out the crankshaft position sensor and there was a small metal shaving stuck on it. After cleaning the sensor engine fired up and ran as it should. Thankfully we were able to return the tb and the map sensor
I call that the "David Syndrome". That little filing (David) brought down the car (Goliath). That happens all the time. Once l had a older Isuzu Prism with a 1.8 that wouldn't rev about 2K rpm (it had the older OBD1) so there no codes, very limited engine data (about 10 or so lines of data) slow processor speeds. After a time found that the tach would go very erratic start jumping around about 2K rpm and the engine would misfire hard, yet idle smooth. It turned to be a loose mounting/ground screw on the igntion module. The module wasn't grounding properly causing a feedback through the engine ecm. Tighten the screw and low and behold the concern was corrected. Engine revved and ran good. Needless to say the customer was very happy.
I cleaned out the throttle body in my dad's truck not that long ago and it fixed the problem we were having, it just surges for a minute every time I drive it in different weather Probably throws plenty of codes but I don't care about those We can't afford to parts cannon, we just drive it until something obvious breaks
Here is my parts cannon example. Used cars sold a 1994 E31 850i coupe V12.) I performed the used car inspection. Customer took deliver of the car. Car failed WI emissions (high HC). Since I did the used car inspection it came back to me (no problem so far.) There are two known problem areas with these engines, intake manifold vacuum leaks and secondary ignition wire failures. My Dealership did not have even a 2 gas analyzer (as compared with a 5 gas analyzer) or a "Sun Machine" oscilloscope type tool so as I could look at primary and secondary waveforms. It sure would have been nice to have these tools to help diagnosing this concern. I could not get a response spraying carb cleaner at the intake to cylinder head gasket point (this would have confirmed a vacuum leak), the idea was a lean misfire) and I could not ohm the secondary ignition wires without pulling the wires loose from the plugs. Service Manager said to do the intake and the plug wires because we had seen them fail on other cars(I think half the wires broke upon removal, wire set was 300.00+ to the Dealer.) Probably 5 hrs to replace the intake gaskets. Car seemed to run fine after the work but again failed emissions due to high HC. The intake was not leaking and the wire set was good . I would not fault most any shop not having an exhaust gas analyzer or an engine O-scope but having these tools sure would have helped with the diagnosis.
Love your videos and this is what I quit working on unless they put all the old parts back on and put cars back together as they should be. I found I have more sanity and not dealing with people that paid 5 others shops and don't feel they should pay much if any. I just will turn this away the work I have I stay backed up nearly out a month with good work from regular customers. I cut off new customers a year ago unless it was service work and quit the heavy work. I do alot of electrical work and have been the guy that all the other shops would call when parts wouldn't fix the issues. I say no a lot now.
I am an expert user of the parts canon but take this warning... You can save a lot of money, reputations and time using a power probe / test light / multimeter / professional grade scanner that can extend live data Parts canons may be necessary if a cars been neglected for 20+ years but generally... if a car is a solid, daily runner that everything works on and a problem surfaces? Testing each component individually. It takes a long time. Google can't always guide you. But it's how you do things the right way. It's frustrating. It can make you feel silly. But it's just the truth.
This is why learning how to test things is so important. It doesn't help that cars are so complicated. On top of that, they're often built on the bleeding edge of reliability and durability.
Lance. What is the last item on a manufacture’s diagnostic tree ? Substitute with a known good unit ‼️. Just go out back and pick one off of your parts tree 😳. This all started with OEM engineers.
Utube Mechs have saved me 1000s of dollars. But one has to do a deep dive and review all. Its like I had a buzzing sound at speed from windshield all said to glue it or have a new windshield installed. Found one comment [remove bug hood deflector] that was pushing air stream to the top of windshield,causeing the noise. Thank God it was driving me Mad lol.
@@Lancemechanics When i got Truck 1yr ag0. At first i thought it was speaker issue. It needed a new windshield too [org/pitted] which I had it replaced $450. Not for the buzzing sounds, and the noise was still there. Glad I didnt glue the hell out of my new windshield. Plus I like the way it looks now.
Having worked for numerous shops I see a lot of shop owners and techs throw oxygen sensors at stuff before they look for leaks I even just had to inform a lady that a shop tricked her into doing a timing chain on her car over an exhaust leak. I don’t know if they even bothered to actually diagnose the issue and I’d be curious if they even did the timing or just charged her.
Also I will say this is where I used to use alldata or Mitchell and show the customer… “this is the path we have to take, replace this, check this step by step show them the hours of diag and parts it will take because let’s be honest people bring in cars with 100 issues and ask for you to fix the one thing and it can be difficult.
Dam you are pounding out the content 👍. I'm sure that it's probably the same on light duty as in the heavy truck. Ya it didn't fix it but it definitely still needed it. I promise the mechanic says to the customer 😂😂👍🇨🇦🔧
Alot of oems have certain parts that the only way to test according to the shop manual is to replace with know good-part. That probably because i work on mostly pre obd fuel injected cars.
Yup, first shop sucks all the gravy out of the car and at the next shop the customer wants the problem fixed cheaply. Unless I missed it, you didn't mention the role that flat-rate plays in this.
Here we have local aftermarket parts stores that will check your check engine lights for free. And a lot a lot a lot of these guys will see the code, say for misfire cylinder 1 and tell the customer yea just put in a new coil pack and plugs. Customer does that and doesn’t fix it. Comes to us and it’s an injector or bad cylinder. Happens a lot here.
I feel like there is a difference in a parts cannon and what I call a problem chain where one thing is causing one thing and another thing causing another so you have to follow the chain of handling x so you can then find y and then fix it and then get to z which was the real problem but all three needed to be fixed. I don't consider that parts cannon
We tend to get the guys that already spent 1000’s throwing parts to get pissed at us when we charge to tell them what’s wrong or we get the never ever worked part that they threw on that is the problem and they think we’re idiots when we tell them their NEW part is bad
I don't envy anyone working on a car post 2010 (on an everyday basis). I try to use the same approach I use as a computer programmer everyday when I work on my cars (divide and conquer).
" what do you mean its 130 dollars to diag, you just hook up the scanner and it tells you what to do" i wish lady, i wish.
Yep@ :(
And listened to her schpeele…
Now price went up again😂
If a shop’s returns bin is always full of new parts… they’re taking the parts cannon approach

Unless I missed it, you didn't mention the role that flat-rate plays in this.
Here we have local aftermarket parts stores that will check your check engine lights for free. And a lot a lot a lot of these guys will see the code, say for misfire cylinder 1 and tell the customer yea just put in a new coil pack and plugs. Customer does that and doesn’t fix it.
Comes to us and it’s an injector or bad cylinder. Happens a lot here.
Oh those free scans drive me nuts lol.
With how much of the proprietary information is kept secret the troubleshooting gets pretty limited.
I feel like there is a difference in a parts cannon and what I call a problem chain where one thing is causing one thing and another thing causing another so you have to follow the chain of handling x so you can then find y and then fix it and then get to z which was the real problem but all three needed to be fixed.
I don't consider that parts cannon
Still feels like it some days
Thank you Lance
Ty! :)
bombadier has some training class recordings on electronics here on yt
The exact situation I'm in with my 2008 Impala. The MAF is bad but I replaced 3 things before figuring it out
It's a pain in the body when they do that :/
We tend to get the guys that already spent 1000’s throwing parts to get pissed at us when we charge to tell them what’s wrong or we get the never ever worked part that they threw on that is the problem and they think we’re idiots when we tell them their NEW part is bad
Oh the new part is bad had to he the most annoying thing on the planet. You have to be a therapist some days I swear
I don't envy anyone working on a car post 2010 (on an everyday basis). I try to use the same approach I use as a computer programmer everyday when I work on my cars (divide and conquer).
It's tedious for sure. You rip hair out haha..
Honestly, I was misled by the thumbnail. I was expecting a different canon and different parts. 🤡
:p
