Ok I have had my check engine light on for a while, I pulled the codes tonight and these are the ones I got

12- Throttle Sensor Full Range (I think I have fixed this, but not sure, need to clear the codes)

30- Spilt Air Selenoid Valve (Have no clue about this one, maybe I removed it or somethign not sure, where is this located and what does it do?)

33- Port Air Solenoid Vale (Have no clue about this one, maybe I removed it or somethign not sure, where is this located and what does it do?)

34- Solenoid Valve BAC (Now I know why this one is on, I removed it, now how do i get it not to throw this code?)

So basically thats my problem now, how do I fix them?

 

Oh and I forgot to mention this is for a 90 NA

 

30 and 33 relate to the Air Control Valve, you know the one that relates to emissions and the air pump.

hugues -

 

well if thats the case then I removed the aircontrol valve and the air pump.

Is there a way to get the ecu to think that there still connected?
