Difficulty of Diagnosis and Repair 2 out of 5

  1. Check to see if there are any other codes along with P0410 and clear your Check Engine Light with FIXD.
  2. 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.
  3. 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.
  4. 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.
