Hello,
Im having issues with my 2009 Dodge Avenger 2.4L VVT, I have changed the camshaft and crankshaft sensor because the check engine light would come on and; even though they were replaced I kept getting the same error codes P0369, P0365 and P0335.
I went to the dealership and had them look at the wiring, the detail states "tested wiring, found improper repairs in starter signal circuit, found intermittent open in F855 circuit, checking wiring found spread pin in PCM Connector 2 (repaired pin); tested vehicle and it starts at this time. Codes were cleared, repaired harness and tested in parking lot."
Now after this was done I took my car to a garage to get my PCM cleaned because the dealership said if the codes come back then its most likely the PCM (but the dealership does not clean PCM's so I took it to a garage I have been going to for most of my work), and unfortunately the codes came back and the garage cleaned the PCM and cleared the codes; my car was fine for a whole month and then after a month to almost the day it came up with the code P0365 and then the next day P0303 when usually codes would pop up a week after having the codes cleared (before I had the PCM cleaned).
I know PCM are very expensive from the dealership and I can not go that way so I am looking for your help if it is possible, could a bad PCM be causing these codes because it has wiring issues internally that can not be seen; because I have the garage telling me its a timing chain issue (because the camshaft and crankshaft codes were coming up at the same time) but the dealership saying its a PCM issue.
I plan on going back to the garage to have them check my spark plugs (because I don't really have a history on the car, so they may need to be replaced anyways) and also having them clean the PCM again with electrical cleaner (ask seen in one of Scotty's videos) to see if the codes don't come back again for a while; but with your opinion could this be a PCM issue or something else?
I don't know a lot about cars, Im learning as I go along so please bare with me if I am confused about some things; Im just trying to fix all my issues and keep the cost down as much as possible. I was ripped off buying this car and not knowing it, I paid $3500 and have already put in over $1,000 fixing problems that were not made known to me; but you live and learn and Im just trying to have the car last as long as I can because I only purchased it in September 2020.
What I have fixed since purchasing:
1. Sway bar links in the front
2. Serpentine Belt
3. Battery
4. Camshaft Sensor
5. Crank Shaft Sensor
Any help would be greatly appreciated!
On a Dodge that age, it could be the PCM has gone bad and needs replacement. I'm not really seeing a timing chain problem in your case and if the dealer scanned it and found improper repairs, I'd probably avoid the garage you have been using.
It sounds like you need to find a better independent mechanic to take a look at it. But to answer your question, yes, it could be a bad PCM. And don't beat yourself up over your purchase. We have all been there at some time. Mistakes are how you learn and as long as you walk away from this smarter from the experience, it is good for you.
That’s a dodge… electronics are known to be terrible.
I recommend you go to a proper car electrician.
If you’d do this from the get-go you’d probably save a lot of money!
they can use advanced scan tools to monitor the exactly singals being sent and they have diagrams, tools and knowledge we can’t even dream of.
I will look into that, thank you!
