Question

How to diagnose and reset the ECM DTC P062F for my 2012 Buick Verano 2.4L? I just replaced the battery, and this code came up

Answer 1

This code can falsely set during a low battery condition. This can also trigger certain HO2S heater sensor codes.

If only these codes are set and the vehicle is not exhibiting low battery symptoms, clear the DTCs and perform a couple of engine starts allowing the engine to run for a minute, then shut down and allow the ECM to power down, about a minute. Restart the engine. If no DTCs reset, no further action is necessary. If the DTCs reset, check the ECM power and Ground circuits, as low voltage to the ECM can cause these DTCs to set.
