I have a 1411 & 1423 code for B1 & B2 SAIs. If the vacuum hose from one of the secondary air injection valves is disconnected (or broken off) will it affect both valves, making the CEL come on with a code for both SAIs?

Bank 2 hose is broken but the B1 side appears to be in good shape.


Thanks,


Rob

 

CEl will come on if the leak is big enough. if not big enough to set a LEAK DETECTION fault it will set a lean running condition fault.

 

It was the vac hose.
