CEL came on, Scanned code PO411. Searched but didn't find a thread. Can anyone tell me what it means, a perhaps a fix?

Headed for the airport today..crappy timing for this

Further searching...maybe secondary air injection..incorrect flow? I'll check for hose/vacuum leaks. Anything else I can check? If need be, should I drive it with the CEL until I can spend more time on it?

 

P0411 Secondary air injection system. Incorrect Flow Detected.

 

It runs during initial start-up to scavenge exhaust right? Sometimes I hear the squeal (winter months). Anything short term that I can do, would it hurt to drive that that? Didn't find any vacuum leaks, no other problems. Car is a 2001 225 with APR chip, cone filter, aftermarket DV.

 

P0411 = air pump, air valve, air hoses also check the fuses /relay under the hood because the pump might not be working at all

 

Thanks,

Any pics of fuse/relay locations? Also trying to track the vacuum line tothe Combi valve..any clues?
