Malfunctioning air pump/air pump relay
Faulty air pump check valves
Blocked air injection system
Blown air injection fuse
STEP 1: CHECK FUSES AND RELAY.
Check the fuse for the air injection pump. If the fuse is blown, replace the fuse and test drive to see if the concern is resolved. Often times if the fuse is blown, it’s due to a failed air injection pump. If the fuse blows again, try replacing the air injection pump and fuse, but make sure to clean out hoses and replace the one-way check valve. If the fuse is not blown, check the air injection pump relay for function. If it fails the test, replace the relay and test drive to see if the concern is resolved.
STEP 2: INSPECT AIR INJECTION PUMP.
If the relay passes the test, try replacing the air pump, but make sure to clean out the hoses and replace the one-way check valve.
