P0692

Fan 1 Control Circuit High

Engine cooling fan control Generic OBD-II High

What it means

P0692 means the engine computer detected an abnormally high voltage on the cooling fan 1 control circuit — typically a short to voltage, an open, or a failed relay. The concern is a fan that won't run when commanded, which can let the engine overheat at idle or in slow traffic.

High

Can I keep driving? Watch the temperature gauge — if the cooling fan isn't running the engine can overheat in traffic. Avoid low-speed driving until it's fixed.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Failed cooling fan 1 relay or control module
  2. Short-to-voltage or open in the fan control wiring
  3. Corroded or loose fan connector
  4. Failed fan motor
  5. Failed ECM (least common)

How to diagnose & fix

Work through it in order

  1. Scan for codes and watch whether fan 1 commands on when the engine gets hot or the A/C is on.
  2. Check the fan relay and its fuse — swap in a known-good relay to test.
  3. Inspect the fan control wiring and connector for a short to voltage or an open.
  4. Test the fan motor directly with power and ground.
  5. Replace the relay, wiring, or fan as diagnosed. Clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0692?+
Only with caution. If the fan isn't running, the engine can overheat at idle or in traffic. Highway speeds get some airflow, but don't ignore the temperature gauge.
Can I just clear P0692?+
It returns until the fan control circuit is repaired — and a non-working fan risks overheating damage, so fix it rather than clearing it.
