The water or coolant temperature sensor 385720500 is used to measure the temperature of the engine coolant which can then be fed back to the ecu to adjust the fuel ignition and timing.
Engine water temp sensor.
Replacing the car temperature sensor.
Helping to ensure more fuel is supplied when the engine is cold or less when the engine is warm.
Even general wear and tear can cause the sensor to erode over time.
Keep your engine cool regardless if the temperatures are skyrocketing outside by making sure your coolant temperature sensor is operating correctly.
Ecu in turn adjusts and regulates the fuel quantity ignition timing.
The engine temperature sensor informs the engine s ecu about the current ongoing variations in the engine temperature.

The sensor will eventually need to be replaced altogether after time.
The data from the engine temperature sensor provides readings for engine temperature gauge on the dashboard.
Based on this data the ecu also controls the additional functions such as switching on.
