Jeep Compass: Hard Start Cold / Overheating!?
ฝัง
- เผยแพร่เมื่อ 18 มี.ค. 2022
- In this video I bring you along as I have a look at a Jeep Compass that came in with a customer complaint of the throttle light coming on, it's hard to start when it's cold out and he says the temp gauge indicates that the vehicle is overheating. He had it an anther local shop and they changed the thermostat so now we need to find out what the real issue is and get it fixed. -Enjoy!

The whole Chrysler company is a substituted value. How do they call that a Jeep?
Don't go there. All car companies do this. Think, new Bronco sport? Yep. How do they call that a Bronco? Oh yes, Chevy too. The new Blazer. No comment.
It's no longer Chrysler. The word is Stellantis which is either a new erectile dysfunction drug or the latest iteration of Chrysler and can't figure out whether it's French or Italian...
@@buckhorncortez It's HQ is in the Netherlands:)
As a Wrangler Rubicon owner, if they have to sell cheap econoboxes to college students and people with bad credit to keep making Rubicons for me, I'm ok with that.
They just released a Wrangler with a 392ci V8 that does 0-60 in 4 seconds flat. The company may be different by name, but for the most part they don't seem all that different by nature :D
When the owner says that the temperature gauge goes way up even before the engine starts, it seemed odd that somebody changed the thermostat when it seems obvious that the gauge is showing an incorrect temperature.
Gives new meaning to the bumper stickers that proclaim, "It's a Jeep thing, you wouldn't understand."
The rest of us need "The Jeep thing, I don't understand" sticker.
And he writes: The only things I am qualified for is oil changes and tire pressure checks. After that I am completely at the mercy of my local repair shops.
However I am still fascinated by your approach to seemingly impossible electrical issues. I’m responsible for at least 5 more subscribers you have
by word of mouth. Wish you were local. Love always,………………
Learned something Eric. Thanks much for the OBD generic vs OEM explanation. You're teaching and helping all of us learn. Good man
Afternoon Eric, my favorite expression you use “money light “
Never thought OEM would lead you astray like that and generic was better in this case. Proves you're never too old to learn. Thanks Eric and keep up the great videos.
It always pays to be willing to learn new things.
GM has some wild default strategies but hey it's GM
43 seconds ago!
You're really pumping these videos out! I hope TH-cam is rewarding you well!
You definitely deserve it!
Been watching for 2+ years now. You are a great diagnostician.
DIY home gamer here. Like most DIY'ers, I have no problems turning wrenches, it is the diagnostic side of things that presents a challenge. I have learned SO much from watching your videos, and become so much better at diagnosing my own problems. Keep up the awesome work, and my thanks for all that you have taught me and DIY'ers all over the net!
Once again, another lesson learned. Never thought about using generic OBDII data in a case like this. Great info and another great video! Thanks!
What did we learn today? If you're going to fire the parts canon at an issue like this then change the thermostat and the temp sensor at the same time.
Other channels try to be informative and entertaining but if you want proper diagnosis then Eric is the best, plus he’s entertaining, well I think so ,
Thanks for the important difference between OEM and generic data. Those little tidbits are often overlooked or not included in documentation. I always try to differentiate the terms data and information with data being the raw values and information being processed data. OEM is information in this case.
I didn't expect to get a door prize when I watched this one! I love take home tips!
Eric, not sure if you’ll see this. But just wanted to say thank you! I’m not a mechanic. But I’ve learned so much! I’ve always been interested in what makes a car operate and everything else. And it’s pretty cool and fascinating to see how intricate and complex Vehicles are. Love your videos.
I had a GM the other day that had 42 codes set in OEM specific. There were voltage high and low codes for nearly every sensor under the hood. They wouldn't clear. However Global show no codes at all. Replaced the computer and that went away, but I had a bad crank sensor and cam sensor. No way to know that till I got the computer to stop flipping out on me though.
Well, I'm in luck because all I have is an OBD II scan tool, then again my '94 Ranger isn't that high tech either. Thanks for another informative lesson in diagnostics Mr O!
Thanks Eric
Just had this Conversation on Friday with my students and showed them like you just did.
Solid tip on always sanity checking with Generic OBD2 values. Always informative. Thanks, Eric.
I just bought a scan tool, nothing fancy. I'm not a mechanic by trade but like working on my own cars. This was a great free lesson. Thanks Eric. You and Rainman Ray are the best cartubers around.
3 videos in a week, why am I so lucky. You are one of my favorite TH-camrs to watch and anytime you post is a good day to watch. 😀
You know it's a Mopar when it needs to have a throttle light! Had a rental liberty and the throttle had a mind of its own. Glad this brand is good job security!
You had me at coolant around the terminals. Like you said, vehicle specific "substitutes what-it-wants-to-see data." Generic is raw. And shorting the 2 pins gave the wiring answer......it's good.
Every time I watch an Eric O video I learn something important. Thank you Eric.
No Jeep cap whilst you're working on a Jeep...not a sponsor? Excellence at SMA!
I am concerned you are too good and all the other shops will have to close! Lol! In all seriousness, we all love you Mr O! Keep up the great work and great videos.
I have always learned something from every video you put out. I always wondered what OEM and non-OEM data was. Now I know
Hey Mr O, loving the extra videos these days !! Thank you .. love your Videos from N.Ireland !
Good to know that scan tool is not going to pull a fast one over on old Erick. I would guess they got you once but not twice. You always play the "heads up" game and you do a very good job of it. Thanks for Sharing!
Good to have a friend who will share hard learned knowledge with you. Thanks
Thanks Eric for taking the time for the teachable moment! 👍
Fantastic information, great subtlety on the difference between OBD and OEM. Nothing but the best, as always. Thanks, Eric!
For a man who doesn't like vehicles?
You would be a perfect shop teacher in high school or training young mechanics!!
I like fixing cars I am just not a "car guy." By that I mean on my free time I don't like cars... not even a little haha
You're my hero. Been watching all your videos for years. Thanks for helping me become smarter and believe in myself.
You do a great job on all the electrical issues. Tom
Great job as always. Your a great teacher and explain troubleshooting easy to understand. Please keep posting all troubleshooting jobs.(my favorite)
I learn every video I watch of yours. In the past you have asked for feedback on the computer/electronics all I can say is keep it coming.
Been a fan for a few years now, always a good video
I'd never thought of that, Thanks for a corrected direction and add smarts on the OBD and OEM information. NICE!!
Another jeep with an issues, I'm shocked (!) great video dude love the content keep the great work up 😁
Solid information on that OEM data issue. Always learning from you Mr.O
Good video, and great advice on the data…I can see how that could lead us down the wrong rabbit hole thinking there’s something else wrong
You are a truly superb teacher Eric O thank you from good old Blighty 👍🏻👍🏻
Thank ya for not leaving us hanging. Ya talked about the Jeep, ya showed us what ya had found.
Eric, tricky one for me, enjoy the learning from you !!
Thanks man
Learned something
I’d assume that it works the same with O2s and MAFs
Putting this to memory
Sure does!
Great lesson Eric on OBD generic vs OEM data. As always great video and hang in there with the old smeller i got the COVID about a month ago and still have no smell or taste.
Eric I'm from the uk been a mechanic 29 years u are a top dog
Learned something new, never new about the auto sub. Thank you Eric. Mrs O peering over your shoulder gave me a laugh (12:15)
Value for money tip of the century right there Mr O.
Another quality video from South Main auto
I hope someone comes up with a car I can replace mine with at some point. It isn't looking good, however. Great video!
Great teacher , information straight to the point showing exactly why your reasoning is correct. Thanks Eric
Interesting. I never thought about OEM data substituting that way. I always thing of it Subbing a real value to Global, for instance a car that has a AFR sensor, substituting O2 voltages to the Global Live data, not the other way around.
I just got bit by this on a patriot yesterday with cooling fan command vs engine temp nonsense. Makes sense now!
Here here!! All hail the diagnostic king!!!! Another superb video!
Used to rebuild my own starters, but now that I'm 67 I find I value my time more, especially when the parts are hard to get. Last year the GM starter on my wife's car developed an intermittent no crank. Electrical feed was OK. The pinion gear end shaft had worn through the bushing right into the housing so I was really glad I got a new one before I tore it out. Harder removal than in this video. The old starter never made noise, just the intermittent no crank.
Great video as always! The thermostat setup is a dual thermostat and kinda complicated if you're not used to the design. The vehicle specific data can confuse ya if you're looking at something you're not already familiar with. Your videos have not only a technical aspect but also a teaching aspect as well, hold your head up high my friend.
In words from startrek!!! Coolest Vulcan sheet on the web ,,, Really good stuff🖖
cool video Eric...awesome teaching methods you have ..thank you !
The amount of electrical issues you chase down is amazing. You almost need to be an electrical engineer to work on cars these days. Thanks for an other video, Eric.
Excellent Information Dr. 0
👍👍
Learn something new everyday. Did not know the difference between the generic and specific obd2. I bet that's one of those tricks Me-Maw taught you. 😁 Good ole me maw. Never let's us down.
You da man!! Know matter what your wife says!! I tend to learn something every time I watch one of your videos. Thanks!! Stay safe my friend.👍🤓👍🤓Randy.
And another informative video from the guru Mr. O
Really enjoy your videos. Thanks.
Great job Mr O.
Great video Erik O. Thanks
I learn so much here. Thank you.
It amazes me that anyone with a reasonable knowledge of vehicles would throw a thermostat at this based on the symptoms.
Agreed, looks like someone pulled the codes, checked the service data, saw the first thing on the list that was a replacement part ( I think it was listed as the second possible fault), slapped it in, and called it done.
Some of the stuff Eric gets from "The Other Shop" is a bit of a tougher diagnosis but this was a bit pathetic. I mean if you're going to load up the parts cannon, with the faults described temp sensor should have been the first option!
Still like the video Eric! Love the way you work!
I'm surprised they let it roll out the door with the light still on instead of guessing the temp sensor next. These morons usually just keep buying parts until it's "fixed".
@@grannyflatgarage7599 The thermostat seems like a go to part for a lot of places, not sure if lazy or incompetent, but considering the temp shot up on a cold engine it makes no sense as a thermostat will never cause that symptom.
@@notavailable9919 true, makes me wonder a lot of the time whether "another shop" is actually "my mates driveway" haha
@@grannyflatgarage7599 Bingo!
man, super fun stuff here. Sure, it's an easy fix, but the big takeaway is how once you're pretty sure it's a sensor, you can PROVE it. Excellent diagnosis, i LOVE this stuff Eric O.
All those with oil cooler have leaks at the T in the top radiator hose.... Gates hose fixes it...
Thanks for the tip about the data substitution.
Great video! No questions, comments or concerns. Although, only 154 days until Demolition Day.
Good to know thankyou.. He says never intending to spend serious money on any kind of OEM scan tool..:)
Hey nice to see u again u saved my life my times good u doing well no let's watch
Looks like the other shop just chose the first thing on the list. How did a technician think a bad thermostat would cause a gauge to read high temp when the motor was dead cold. I'm no tech, but as soon as Eric said the temp gauge goes up when the car is cold, my mind said temp sensor. Not having a bunch of fancy scanners, I would have just unplugged the sensor and looked to see if the gauge went back to zero.
Unfortunately because the temp gage is networked it likely won't read cold unplugged due to the open circuit. In most cases the gage will indicate an overheat condition as that would get your attention.
@@PhillipBailey Read again- I said when the temp gauge reads hot with a cold engine, the first thing that comes to mind is a sensor.
Solid information, thank you for the lesson.
Thanks for the free education!
Another good video
Keep it coming
Eric O
Thanks again , very helpful
Very nice explanation
very true it uses value so the vehicle will run in limp mode to get you to a good mechanic hum hum sma
Shoot…..never had that problem on my MG….ha…ha….good video Mr O as always
owner states vehicles temp gauge is pinned high at cold start.... shop blames thermostat and replaces it????? sounds like a shop that should be avoided at all costs... Maybe I heard is wrong and you stated you observed it pinned at cold start.. but the point is the other shop didnt? definitely a shop that should be avoided...
Kinda my thoughts but hey .... what do I know lol
Have you ever seen substituted voltage values? I can see how it would substitute an interpretation, but substituting an actual voltage value would be another step toward confusing diagnostics.... In any case, it is too bad there isn't a flag to identify when a value is substituted.
Another guy just asked that and I thought about it for a bit and I don't think I have but I am going to pay attention now and see. Great question !
All the sensors on a vehicle with electronic engine management generate an analog signal (varying voltage). At the PCM (powertrain control module) the analog signal is converted to a digital value. Then logic within the PCM analyzes this digital value and determines if it makes sense when compared to other values (oil temperature, intake air temperature). If it does not then a value is substituted. So there would be no reason for the engine management logic to substitue a value for the analog signal. Just substitue on the converted value; analog to digital. And as Eric O has indicated a substituted value parameter is used to keep the engine running (if possible) and not leave the vehicle stranded and non-operational.
Unfortunately it looks like the flag is just using your noodle. 😅
Thanks Eric, interesting video.
Thanks Eric O. Never really understood the benefit of using Generic. Good to know.
Great information thanks Eric
Another great video! Well done. Wish you were around here(CO) and worked on VWs.😜
Good stuff Eric!👍😎
Very cool with the screen captures!
great job like the stuff you do god bless
Been watching this channel for so long now I know what's about to happen....
Been to another shop (check)
parts cannon (check)
bunch of strange codes and behavior (check)
Someone's been here before (check)
Go to the fridge to get a beer and Eric's got it diagnosed and fixed before I get back (check)
Thanks for the tip
Thought it was going to be a bad ground again but also learned something
I always learn something here. 😊
Omg I used to have the 2.4 in a Sebring! I did not expect to see that thing in a jeep!😳
As alway's entertained and i learnt a thing or two cheers😊🤣😎
