okay guys my car was throwing cel number 3 wich is map sensor i went ahead and replaced the plug in top of the intake manifold and that fixed the problem, but now its throwing cel 5 with is also map sensor when i unplug the map sensor in the top it goes back to 3, so is there another map sensor in the motor that is not the one in the top??

 

1. Check the green ground wire for a good ground.
2. Check the yellow wire for a 5 volt signal.
3. Check the white wire for continuity to the ecu pin for map sensor signal.
