Thread: Secondary Air Pump Code P0411 Help

The valve is easy to replace, just rock the engine forward like you mentioned. With the engine mount dog bones taken off, the e-brake off, and the car in park, push the car forward and back. That will make the engine rock forwards and backwards, and when it jumps forward, slam the e-brake. That will hold the engine forward without using straps.

The hardest part is taking out the two lower bolts that hold the bracket and valve to the engine, they're against the firewall basically. Then two nuts that hold the metal tubing which are down in the same spot, but are actually visible.

To find the rear bolts for the bracket, I just follow the bracket down to the end and feel for them, they actually hold both of the brackets on the rear of the engine.

That's basically it, the rest you'll figure out as soon as you see it. I've had mine off a bunch of times, but now I'm getting that code too. I hate how vague the code is, basically anything can be wrong in the system. I'm hoping the exhaust leak in my downpipe gasket is the cause. I'm pretty sure it's just the pump, relay,and check valve on the 04+.

Thanks for the info Nik,

I figured it was going to be one of those 6 bolts that you can only get 1/8 of a turn of the wrench at a time jobs. No really hard, just a pain.

I'm going to attempt the swap out this afternoon. I'll try to repost how it goes and any info that can help future forum members out.

After doing more digging into the part swap, I found an older post on this forum that has great info, http://www.grandprixforums.net/air-i...tml#post751569 . Should help out anybody in the future.
