Temperature Coolant Sensors Online


The engine’s temperature coolant sensor is a comparatively uncomplicated sensor, which monitors the internal engine’s temperature. When the engine is running, coolant inside the engine obstructs and cylinder head(s) absorbs heat from the cylinders.

The coolant sensor identifies the temperature change and indicates the Powertrain Control Module (PCM) so it can notify if the engine is warming up, cold, overheating or at normal operating temperature. As the sensor’s input to the PCM impacts the operating strategy of the whole engine management system that is why coolant sensor is so very important. This is the precise reason why the coolant sensor is known as the "master" sensor.

Numerous ignition, fuel, emissions and drive train operations managed by the PCM are impacted by the engine’s working temperature. A different operating strategy is applied when the engine is cold compared to when it is warm. This is performed to improve cold driveability, idle quality and emissions. Accordingly, if the coolant sensor fails or is giving the PCM an incorrect reading, it can disturb a lot of things.
