My check engine light came on and I used the trick from the forum with the wire and I think I through a 41, but im not sure!what classifies it as a long blink? I either through a 41, or a 5. a 41 is the primary oxgen sensor does anybody know where this is located? a 5 is manifold absolute pressure sensor. The blinks were 4 normal blinks about 1 second or 2 lit solid, and the 5th blink was really quick flash so i think i through a 41, so if anybody knows where number 41 is that would be great and also if i did this correctly. I also just put on a AEM cold air intake about 1 month ago, so can this have anything to do with it?

 

Well the primary is the first o2, its on the exhaust manifold. And the map is on top of the throttle body.

Also they called it a Primary oxygen sensor heater. Is this still the one located on the exahust right before the cat?
