Code P0410
 

Hey fellow s2k guys, I'm keep throwing this code and Iv changed out the relay and pump, checked for leaks, everything. Is there anything I could be missing?

Please shed some input or thoughts. My tags are due march and idk what to do. Please help!!!

Did you check the flow of the air check valve?

Where is that located?

As far as I remember, P0410 "Air Pump Circuit Malfunction" is caused by a fault in air pump system (e.g. pump not turning on) NOT the vacuum system. If it were a vacuum problem, you'd throw P0411 "Secondary Air Injection System Incorrect Flow".

Can you hear the air pump after a cold start? FYI, the pump is located under the driver side headlight.
Inspect:
-The pump (for stator shell melting, proper operation)
-Air pump relay for proper operation (located next to air pump)
-Air pump fuse (small under-the-hood fuse box located near the ABS)

May not be related but here's a service bulletin:

That's weird, the code im throwing is a for a secondary air injection system. So I swapped out the air pump and relay. I will check all of the above.

if you can't fix it and just want to bypass it with no CEL, do what I do and get an air pump simulator from izze engineering.

You can leave your air pump alone and install this, or remove/sell/throw away anything from the air pump and not worry about the cel again.

Never thought of that. Is that something I buy online or I can get at advance/auto zone?

google search izze engineering. Someone one this site told me about it so I jumped on it.


but here's the link

I've been running it for over a year not a single issue.

Does the car have an OEM intake? If not it is most likely the orientation of the check valve. Normally P0411 but I have seen P0410 thrown as well (when revving a cold engine to see how the new intake sounded).

It was a fuse. Thanks for all the info guys!
