PO410 code - blue check valve

Could this be replaced with another check valve of the same size ? Seems you can find many out there, just not an exact brand / part # match.

Most of the time this is not the check valve but instead the RCM, relay control module.

99% of the time code PO410 is burnt relay contacts on the air pump relay in the relay control module. Bet your's are burnt.
I can replace the relay for you.

The P0410 code is a generic code that covers quite a few faults in the Secondary Air Injection system not just the blue valve.

Check the RCM for burnt contacts on the #5 relay shown here, CLICK
