OBD-II Error Code P0692: How to Fix It (Fan 1 Control Circuit High)

Q: What does error code P0692 mean?

P0692 means the PCM has detected a high voltage (above normal) in the Fan 1 control circuit. This usually indicates a short to battery voltage or a faulty component like the relay, fan motor, or wiring.

Q: Can I drive with a P0692 code?

Possible but not recommended. The cooling fan may not operate properly, leading to engine overheating, especially in stop-and-go traffic or hot weather. It's best to fix the issue promptly.

Q: How do I clear code P0692?

Use an OBD2 scanner to clear the code after repairing the underlying issue. Simply clearing the code without repair will likely cause it to return.

Q: What causes code P0692?

Common causes include a faulty cooling fan relay, a blown fuse, a bad fan motor, damaged wiring or connectors, or a short in the control circuit. In rare cases, a defective PCM.

Q: Is code P0692 serious?

Yes, it is moderate severity. It can lead to engine overheating if the fan fails. Address it quickly to avoid potential engine damage.

Abstract

Error code P0692 indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the fan 1 control circuit. This typically means the circuit voltage is above the normal operating range, often due to a short to battery positive or a faulty component.
