Anyone come across these codes before? The CEL came on today and I read the codes but not sure what to make of them.
I never had any problems with mine (so I know nothing about it); but this is what other people put in the bestlinks over time on the secondary air system:secondary air pump is not supplying sufficient air during operation
The air valve opens via a vaccum drawn by the vacuum pump, which is actuated at cold start, when the air pump is actuated. It closes when vacuum is absent to prevent exhaust backflow into the air pump.Replaced the pump and the valve. Did not have to replace the fuse. Checked to see if the pump was blowing lots of air. I just need to clear the codes and see what happens next.
I was wondering how the air valve is open, is that from force of the air?
