A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Thermostat stuck open — the engine doesn’t warm up
- Low coolant, air lock around the sensor
- The sensor itself
What you can do yourself
- The second coolant temperature sensor is usually at the radiator outlet or in the cylinder head. Check its connector.
- With this code the fan may run all the time and the engine may be hard to start.
- Watch the temperature gauge, especially in traffic and in hot weather.
Stop and don’t drive on if:
- The Check Engine light is flashing
- The temperature gauge is in the red or the overheating light is on
- The red oil pressure light is on
- Smoke from under the bonnet, a burning or petrol smell
- Strong jerking, knocking from the engine, or the car barely moves
