Thread: Where Is The Relay For The Secondary Air Injection System?

Anyone know? I can't find this anywhere online. It's not on my Alldata account and it's driving me nuts!

Car's an 07.

What does that mean?

I just want to know where the relay is located so I can make sure it's working.

NU3 = crappy California emissions secondary air pump bs on your car.

Meaning, if there's a question that comes up from AllData, you want to select NU3 based cars. In the GM FSM it specifically asked. If you don't select it... no relay info, no pump info..no anything else info relating to it.

Beyond that attemp at help, I'd be stating the obvious "in the relay center". And we all know that's not what you are looking to hear. Surely you checked there already.

It's not in with the other relays. From what I could find online it's over near the air intake. There was one good size relay there that I did check, but I'm not 100% I have the right one.

Thank you for the Alldata tip. I'll try that. I have a subscription for that specific vehicle. Whenever I do a search on the Secondary Air Injection System Relay, it just give me a diagram of the actual relay.

Thank you!

I found the schematic on Alldata but still couldn't find anything related to the location.

If the code comes back and I have to get in there testing, you have saved me a lot of searching.
