Inspection Procedure

NOTE:

There is a possibility that the DTC P062F is issued from the ECUs of the ECM and TCM.

Use Techstream to conduct a health check to confirm which ECU the DTC is issued from and then inspect the related system.

HINT: 

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
