The ECM is a crucial component of the vehicle's engine management system, responsible for controlling various functions such as fuel injection, ignition timing, and emissions. The power relay sense circuit is designed to monitor the voltage levels of the power relay that supplies power to the ECM. When the voltage in this circuit is detected to be too high, it triggers the P0690 code.

- Faulty ECM power relay.
- Damaged wiring or connectors in the sense circuit.
- Malfunctioning ECM.
- Issues with the vehicle's battery or charging system.
- Corrosion or poor connections in the electrical system.
