The P062F fault code can mean different things depending on the manufacturer. For Chevrolet Traverse and other Chevy vehicles, it typically points to a problem with the throttle control's programming and its communication with the powertrain control module. The most common cause is issues within the electrical system, such as a faulty throttle control, shorted wiring, or connectors. Low system voltages or voltage spikes could also trigger this code by damaging circuits in the PCM, or if the PCM's calibration is tampered with incorrectly through aftermarket modifications. While this diagnosis is quite broad, it provides a starting point for troubleshooting.
The p062f code on the Chevy Traverse indicates a problem with the engine control module's long-term memory performance malfunction.
