Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary.

To ensure no other trouble code remains on models with A/C, perform following:

  1. Turn on A/C and blower motor. Drive vehicle for at least 5 minutes and attain a speed of at least 40 MPH. Ensure transmission shifts through all gears.
  2. Upon completion of road test, turn engine off. Restart engine, and let it idle for at least 2 minutes. Turn engine off. Connect scan tool to PCM DLC.
  3. Read all trouble codes. If repaired trouble code has reset, repair is not complete. Check all pertinent Technical Service Bulletins (TSBs), and return to TEST TC-1A, if necessary. If another trouble code exists, return to TEST TC-1A and follow path specified by other trouble code. If no other trouble codes exist, repair is now complete.
