Engine Cooling Fan Signal High

on 2003-2014 Volvo XC90 4.4L V8 · AWD

What this code means

The ECM detected that the engine cooling fan speed feedback signal is higher than expected. The fan may be running faster than commanded or the feedback signal is erratic.

Common causes

  • Faulty fan speed sensor

  • Wiring short to voltage
  • Incorrect fan motor installed
  • ECM input circuit fault

Diagnostic steps

  1. Monitor fan speed feedback vs commanded speed
  2. Test fan speed sensor signal
  3. Check wiring for shorts to power
  4. Verify correct fan motor part number
  5. Test fan control module

Repair notes

Replace the fan speed sensor or fan control module.
