Hello, my name is***** code sets when the PCM detected an unexpected voltage condition on the Electronic Pressure Control (EPC) solenoid control circuit. This fault can cause maximum EPC pressure, harsh engagements and shifts. This would most likely be caused by a failed EPC solenoid. Here are replacement instructions, let me know if you have more questions. Thanks.
Thank you, ***** ***** been replaced code persist thank you
Then next step is testing wiring between PCM and solenoid, if good replace the PCM. Let me know if you have more questions, thanks.
Ok great! So what am I looking to find on the wiring? Thank you and please excuse my ignorance.
You will want to unplug solenoid and unplug PCM, wire should have under 5 ohms resistance between the two points and if so replace the PCM. Let me know if you have more questions, thanks.
Ok I'll check that and get back to you thank you
Sounds good, I'll talk to you then. Thanks again and have a good night.
Yes a have 4.5, 4.omhs
You should have under 1 ohm on each wire. If you are sure test is being done correct then next step is looking for wire damage or running new wire.
Sorry I got confused you said under 5 ohm resistance on earlier message, now it should be under 1 ohm?
I meant to say under .5 ohms.
Ok great so 4 to much, so what should I do next, thank you
If you are sure wire was tested correctly then next step is to follow wire to find damage or run new wire.
I'm sorry so the wires need to be checked from pcm harness connector to the epc conector correct? Not the transmission connector side an epc. Thank you
That is correct.
Ok hold on
No problem, thanks.
