Inspection Procedure

NOTE: Read freeze frame data using the hand held tester or the OBD II scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
  1. REPLACE THROTTLE W/MOTOR BODY ASSY (See  REPLACEMENT  )
