Inspection Procedure

HINT:

Read freeze frame data using a hand-held tester or OBD II scan tool. Freeze frame data record the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, 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? 
   • YES: Go to DTC chart (See  DIAGNOSTIC TROUBLE CODE CHART   ). 
   • NO: Replace mass air flow meter.
