Default At loss with PCM

If I do need to change my Engine Control Module how do I get it apart? Can't even disconnect the wire connectors on the front side of it Pulled back the red clips but unable to unplug the four plugins. Getting deeper and more lost as I go along. Told I need to know the OE # before ordering replacement, guessing it is on the inside of unit if I ever get it out.

PS. Waiting to hear back on my post of P0032 and P0038 code display

I believe that someone meant you need your VIN # to order a PCM?
I can not see why an OEM number would work because your would still need the VIN to get the correct speed sensors set.
Maybe you should recheck that with your intended supplier.


How did you determine that you have a failing PCM?

Your codes are your 2 sensors. I recommend you properly cleared the codes and than see if they both return

Thought it to be PCM after searching older posts, My code reader said Heater Control Circuit H. 9h Bank 1 sensor 2 ...what ever that means. I'll put that in search and see what comes up.

They are your(h)02 sensors. But given how the DTC was activated I recommend that you clear the DTC and cycle the engine and re check.
Use a Diagnostic scanning tool to perform this and than let us know.

I wouldn't jump to the conclusion of a faulty PCM yet you don't have enough testing yet.

Tried to download repair manual but PC security shut it down. Don't have access to Diagnostic scanner so at this point thinking of changing the two O2 sensors (once I locate where they are....HELP! and if that doesn't work the PCM).

If you have to order a PCM:
Ordering a PCM for my 06 and they wanted the
Module P/N mine was P05033426AF which is found on the outside of the PCM
maybe under the mounting bracket and the VIN
The 4 connectors on the PCM are black on the outside and has color coded pin connectors inside and keyed to match the the PCM. To remove just push down on the release tab after releasing the red lock.

my 01, 03 and 2006 Sensors are keyed different on the wiring end, #1 is on the lower end, top side of the cast iron exhaust just below the Radiator over flow tank, and #2 is on the catalytic converter, ( easy reach for ground hogs to chew threw the wires)

OK now I see where the two sensors are located on my 2004 Turbo (exhaust manifold and catalytic converter) and they look to be interchangeable...are they the same? After connecting ground wire back onto battery the 0032 and 0038 codes were erased and car started right up with no check engine light. Not going to chance driving car because don't care to break down someplace away from home and know it is going to happen again. Should I replace the two sensors and the PCM just to be safe or could something else cause engine to quit at unexpected times? Thanks for the help here and sorry to be a pain about it.

You did not clear the codes by the battery disconnect.

You should re check using your diagnostic tool before spending money on parts that may not be bad.

No, the one on the manifold is upstream & the catalytic converter is downstream.
If the O2 sensors are bad, the codes will comeback when you drive it next...usually within 5 miles.

Just downloaded manual and reading fault codes for P0300/ P0032 and P0038 all suggest PCM failure. Put code reader back and got a P0562 reading...System Voltage Low, started car no problem and no check engine light on yet. I'll put battery on charger over night and look into this again tomorrow. Thinking a new Chrysler 200 would erase my overheating head syndrome.
