PCM issues?
So I've been hunting down ground issues for a while now and the latest are the cooling fans not working. I can ground the 335 grn wire from the PCM and the fans come on. So fuses, relays and all are ok. And it's not a temp issue, no fans with A/C and I have a programmer so the fans should turn on at 180.
Other odd ball issues which may or may not be related:
Inaccurate oil pressure gauge (dances all over)
Drivers side key fob doesn't work
Drivers Door hatch switch doesn't work
Alternator turns off at idle, runs 13.7-14.1 above 1k rpm (brand new)
First of these issues was the oil pressure gauge reading weird (will go up on off throttle).
Anything else I can test on the PCM? I have a FSM, but running out of ideas to look up in it. Thanks for any help or ideas. I think at least with the fans, it's the PCM. Anyone have a preferred source for one if I go that route?
