Question about 2002 Pontiac Grand Prix
Was told that when this light came on that the air injection pump had water in it and needed replacing. What does this pump do and where it is located on the engine?
Secondary Air Injection System Description
The secondary air injection (AIR) system helps reduce exhaust emissions. The system forces fresh filtered air into the exhaust stream in order to accelerate catalyst operation.
I have had no luck on the location, but it is down low on most GM near the front of car under the hood, it is very big with hoses comming out of it and going to the engine,
