Inspection Procedure

HINT:

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. Are there any other codes (besides DTC P0101) being output? 
    1. NO : Replace MAF meter. 
    2. YES : Go to relevant DTC chart (see  DIAGNOSTIC TROUBLE CODE CHART  ).
