The P065A fault code refers to the Generator System Performance.

In this case, the Engine Control Module (ECM) uses the generator turn ON signal circuit to control the generator in the vehicle. The ECM sends a 5 volt signal to the voltage regulator via the generator turn on signal circuit to enable the generator. However, if the generator does not respond to the ECM’s ON signal, the ECM sets the P065A fault code.

This code indicates that there is an issue with the generator system’s performance.

It is important to address this fault code promptly to ensure proper functioning of the generator in the vehicle.
