P0116Engine Coolant Temperature Circuit Range/Performance
Voici ce que signifie le code défaut P0116, pourquoi il apparaît et que faire à son sujet.
Système: Fuel & air metering
Généralement sans danger sur de courtes distances, mais faites-le contrôler rapidement.
Ce que signifie P0116
The engine computer checks the coolant temperature reading and decided it does not make sense compared to other data, like how long the engine has run or the intake air temperature. The signal is electrically present but the value is out of the expected range or changes too slowly. Often this points to a coolant temperature reading that is stuck, lazy, or biased.
Symptômes courants
- Check engine light on
- Possible poor fuel economy
- Harder cold starts or longer warm-up behavior
- Cooling fan running at the wrong times
- Temperature gauge reading inaccurately
Causes courantes
Classées de la plus courante à la moins courante.
- 1Faulty or aging engine coolant temperature (ECT) sensor
- 2Low coolant level or a thermostat stuck open (engine never fully warms)
- 3Sensor reading biased by corrosion or poor contact
- 4Wiring or connector issues at the ECT sensor
- 5Air pocket in the cooling system near the sensor
Que faire
This is usually an emissions/monitor issue and the car is generally safe to drive in the short term. Check the coolant level and condition, and have the ECT sensor and thermostat tested with a scan tool. Replacing a cheap, lazy sensor or a stuck-open thermostat commonly fixes it.
