Inspection Procedure

NOTE:

There is a possibility that the DTC P062F is issued from the ECUs of the ECM and Hybrid vehicle control ECU. 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 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.
