SAIS air change over valve replacement

[hancock1701]

Hi guys,

I've had the two codes P0410 and P1411 coming on every ~100 miles. I've been clearing and ignoring the two codes but it's getting really annoying that I decided to address the problem. After searching and reading, my question is that is it a do-able job to replace the air change over valve, since from what I read, space is really an issue to get to the valve and removing the intake manifold doesn't seem very easy?

Please advise, thank you!

Several other things can cause P0410 and P1411 codes. The SAI pump may not work, There could be a leak in the vacuum tank. There could be a leak in one of the lines or connectors that affect the change over or shut off valves. See diagram: 2.7l / 3.2l "s" 2000 And Up Air Injection In my case, it was the vacuum tank.

It could be a simple vacuum leak, you should inspect all the vacuum lines in the SAI system first. A common problem is a broken vacuum line in the system, the lines get brittle with age. That's what my issue was when I had the same trouble codes.

Thanks guys. I just finished building my home made smoke machine, so I will be testing the vacuum lines soon. Hopefully the problem will be just a broken vacuum line or a bad air valve and nothing crazy.
