P0121 with NO a/c To give you some back story -
Just got the car back together a couple weeks ago. Intalled the PCMforLess PCM that they sent me. Did the relearn it required, etc. Intermittantly the check engine has come and gone.
So I was doing a bit of research and found the low pressure transducer for the a/c and the TPS use the same 5v from the PCM. Being that my A/C is removed, I am wondering if that is the cause of the CEL.
We checked the connectors/wiring etc for the TPS - nothing that we can find.
If the Transducer is in fact the issue - anyone have an idea of a way to fix the issue with the A/C out? I goofed and cut the lines rather then gracefully removing it because I was getting frustrated haha.
The next idea was swapping the TPS
All help is appreciated! I need to go to emissions! lol
