Inspection Procedure: Notes

HINT:

• The following troubleshooting flow-chart is based on the premise that the engine is cranked normally. If the engine will not crank, proceed to the PROBLEM SYMPTOMS TABLE  .
• 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.
