Why does the fan come on when the car is first started on a 1990 Pontiac Sunbird the temp sensor has been changed?
the fan relay sensor is out of it.
1998 Pontiac sunfire will not start it does not get a spark and i changed the ignition coils and the module below it please help me get it started thanks?
You do not reset the check engine light on that year of sunbird, it will go off automatically whenever you fix whatever problem the computer is reading. Most likely it is one of your sensors that is malfunctioning. Check your Air Intake Temp Sensor (AIT) and your Oxygen Sensor (O2) as they are the most likely culprits.
I think, and I THINK it is under the plastic cover on the left side of the engine, at least it is with a 2.0 4 cylender motor. You have to remove the belt covor than the belt, than the sensor should be visible. I say this because i read it in a Pontiac manual, that plus there are wires running in to the covor. Hope it helps
