Well I unplugged and replugged in quite a bit of stuff today.


I got codes


12=normal

15=under temp

33=map high

34=map low

36=IAC TPS kicker fail ( has to do with the idle speed control actuator/solenoid)

42=EST monitor error( PCM has open or grounded IC or bypass circut)

45=O2 rich

54=Fuel pump relay fail


this is the first time for code 54 for me. Now I see what EST monitor is. 33 34 42 and 45 I would expect.

36 is probably because I disconnected vacuum from it for a little while.

15- I will check voltage at the Coolant temp sensor tomorrow. It is fairly new(april) but is a shmucks part
