Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
The P0302 and P0202 returned after the injector relacement?
Ok, do the injectors all have power on pink?
what does that mean?
The injector circuit, the P0202 is what we need to concentrate on.
The injector gets full power, 12V with the key on then the Powertrain Control Module (PCM) controls the grounds.
If it gets full power then the ground side or the Powertrain Control Module (PCM) is at fault.
how would you check that?
the power you check with a test light,
Then test the wire for resistance on the other to the Powertrain Control Module (PCM). If that is good then replace the Powertrain Control Module (PCM) since it is the last step
ok then if thats not good what do i have to do
repair the wire, either power source or the return to the tank
Powertrain Control Module (PCM) sorry
So is 202 the primary code and the rest are more or less "symptoms" of that one?
and if the PCM ends up replaced will that take care of all of them, or just 202, and then we just start working on the other ones that remain one at a time?
They are related to the misfire.
ok, dumb question... just called to price PCM... is it ECM too? They said they dont even have one listed for the car?
ECM is PCM, and yes they should have one.
so its an engine control module?
just want to make sure Im looking for the right thing.
theres ..only one right? so if we replace ECM... problem solved.... ? in theory
If the wiring is good then yes, but we cannot simply jump to that.
With the other codes it is far more likely to be faulty wiring.
ok.... now that ive sorted PCM/ECM... if the wiring is bad... what then?
Then you repair the wires, run a new section of repair/seal the one that is chaffed and rubbing.
the wires for the injectors?
yes and the other engine sensors.
ok which other sensors?
The purge solenoid, Mass Air Flow sensor (MAF) sensor, cam sensor and actuators.
do you think that the problem that we are having would fall under this recall? 05539A -- PCM INTEGRATED CIRCUIT CHIP DAMAGE - REPLACE PCM
Possibly yes, but you will need to call the dealer to see if your VIN is covered by it.
ok... thank you for all of your help, it is greatly appreciated!!!
Is there more Ic an get you?
no, we are good for now, thanks so much.
