Engine Coolant Temperature Sensor Output Voltage. your car’s coolant temperature sensor usually has a negative temperature coefficient (ntc), which means its resistance decreases with a rise in coolant temperature, resulting in a reduced voltage output signal. the engine coolant temperature sensor is a vital component that measures the temperature of the engine’s coolant and sends this information to the engine control module (ecm). check the resistance of the engine coolant temperature (ect) sensor, and scrutinize the wiring and connectors for any harm. In this measurement example the signal voltage. the ecu is able to determine the engine temperature from the sensor signal voltage and adjusts the injector opening time. the pcm supplies a reference voltage (typically 5 volt) and constantly monitors the ect sensor signal. The ecm then uses this data to adjust the fuel injection and ignition timing to ensure optimal engine performance. the purpose of this test is to evaluate the voltage output of an engine coolant temperature (ect) sensor as the engine coolant temperature increases. A defect sensor can indicate a voltage of 1.5v at cold engine and 1.25v at. How to perform the test. the normal value of the ect sensor voltage is 2v at cold engine and 0.5v at warm engine.
