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

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.
