Possible Causes

Shorted NTC sensor, Pinched sensor wiring, Moisture in connector, Failed main control input circuit

How to Fix / Troubleshooting

Safety first: Disconnect power before testing.

  • Inspect wiring: Check the sensor harness for pinched or rubbed-through insulation causing a short.
  • Test sensor resistance: If resistance is near zero ohms, the sensor is shorted and must be replaced.
  • Dry and clean connector: If moisture is present, dry thoroughly and apply contact cleaner.
  • Replace sensor or control: Install a new water temperature sensor. If E72 persists with a new sensor and good wiring, the main control board may be defective.
