P02E3 Help!

[Anthony1]

Hello, fellas; it's been a minute.

I am working on a 16 2500 CCSB tradesman.

It has a high P02E3 intake valve control circuit.

I have performed the RAM diagnostic procedure and found that pins 95 and 96 have a battery voltage with the key on.

95 is supposed to be the motor ground, and 96 is the power.

Both shoes are 13v with a key on.

I confirmed the harness is good, and there are no shorts.

What I found is that 95 and 96 with C1 disconnected show .5 ohms between the 2 pins at the PCM.

She fired?

The pro-demand procedure and FCA both condemn the PCM, but I'm unsure.

Please help.

My advice would be to follow the attached troubleshooting procedure step by step.

Do not add any steps or speculate.

With both PCM and EGR Valve disconnected, there should not be any voltage on K673 or K674 and above 5 Ohms resistance between them and K834.

Check for open or high resistance on K673 and K674 between the EGR valve and PCM.

All the above checks need to be performed with both the EGR Valve and PCM disconnected.

Then, proceed with step #9 at the PCM.
