Hello all,

I have scanned through the threads on the P0410 error code. After reading I started my investigation with the function of the air pump. I found that the air pump does not run with the engine running when cold.

I had already replaced almost all of the vacuum tubing when I had the intake off a few months back. Also replaced the check valves during that service. The CEL came on months after so I do not believe that it is related.

I though that I'd replace the relay but am having trouble locating it. I do not have a service manual and wonder if someone can help me out with a diagram or photo.

Thanks,
Kirk

 

the air pump usually will run for a minute or two when the car is first started cold . It usually will not run when warm.
