What does the Coolant Temperature Sensor do and how does it affect engine operation on BMW 428i?

The Engine Coolant Temperature sensor (ECT) has a negative temperature coefficient (NTC). This means its resistance decreases as coolant temperature rises. The ECM varies ignition timing and air/fuel mixture based on engine coolant temperature, with a 5-volt reference voltage. The voltage drop across the sensor varies with engine coolant temperature. If the ECT sensor input has a fault or is implausible, the MIL lights after OBD II fault criteria are met and that causes the ECM to apply a substitute value of 80 degrees Centigrade (176 degrees Fahrenheit) to allow the engine to run while changing the ignition timing to a basic safe level. Ect Sensor Adjustment Location The ECT sensor is located at the front of the cylinder head, after the engine is allowed to cool completely the plug is unlocked and removed and the coolant temperature sensor is then removed. You must prepare to catch any dripping fluids. After the replacement, check coolant level and top off when necessary.
