Greetings all. I have a 2012 Maxima that belongs to my daughter giving me fits. So far, I've checked for leaks, changed a bad PCV and replaced all the small top vacuum hoses to the intake. Also, we had a new PCM put in and programmed after our shop suggested it. Still, codes persist. This past week I replaced the throttle body (along with attached TPS) and had my shop do a relearn. I've also replaced two of the four EGR solenoids that tested bad... it has had four separate MAFs on it (2 OEM, 2 aftermarket as a shot in the dark), all with the same code, and the same with the original PCM. Three separate people (besides myself) have suspected the harness, but all of us have checked the pins and it's always tested normal. I've officially ran out of possible leads, so here I am! Thanks for any help.

PS - the filter is clear and doesn't appear to be a problem.

 

Did you clear the code with a diagnostic tool? It is my understanding that is a requirement as the code will not go away on its own after repairs. I only ask as you didn't say in your post.

 

Hey Richard, yes I cleared the OBD code each time I installed a new part. Also, I typically had the battery terminals disconnected during install, and the p0102 would come back on immediately after startup, followed roughly 3-5 seconds later by the slip light. Thanks for the reply!
