P0115Engine Coolant Temperature Circuit Malfunction
Voici ce que signifie le code défaut P0115, pourquoi il apparaît et que faire à son sujet.
Système: Fuel & air metering (coolant temp sensor)
Généralement sans danger sur de courtes distances, mais faites-le contrôler rapidement.
Ce que signifie P0115
The engine computer detected a problem with the engine coolant temperature (ECT) sensor circuit, meaning the signal is missing, out of range, or unreliable. The computer uses coolant temperature to control fuel mixture, idle, and the cooling fans, so a bad signal can affect how the engine runs. This code is about the sensor circuit, not necessarily actual overheating.
Symptômes courants
- Check engine light on
- Hard starting, especially when cold
- Rough idle or poor cold-running performance
- Increased fuel consumption
- Cooling fan running too much or not enough
- Inaccurate temperature gauge reading
Causes courantes
Classées de la plus courante à la moins courante.
- 1Faulty engine coolant temperature sensor
- 2Damaged wiring or corroded/loose connector at the sensor
- 3Open or short circuit in the sensor wiring
- 4Low coolant level exposing the sensor (less common)
- 5Engine control module fault (rare)
Que faire
Have the coolant temperature sensor and its wiring tested, as the sensor or a connector problem is the most common cause. The car is usually drivable, but get it fixed soon because a wrong temperature signal can hurt fuel economy and cold starting. If the temperature gauge reads abnormally high, stop and check for actual overheating before driving further.
