2001 Chevrolet Tahoe Question: Fault Code P1415, secondary air injection sys malfunction, left bank

what does it mean, how do i correct it? -
Answer 1
in the morning, your air pump works for about 15 seconds to burn unburnt fuel when the engine is cold. it may or may not be working. a shop with a scan tool can test the pump and check valve for proper operation and determine the failure. a guess can be very expensive. i would get an expert opinion. roy -
Answer 2
replace the check valve. -
