ENGINE MANAGEMENT SYSTEM - V8
Thermostat Monitoring sensor
The thermostat monitoring sensor is located in the radiator, adjacent the bottom hose. The ECM compares the
temperature measured by the thermostat monitoring sensor to the temperature measured by the ECT sensor. If the
difference between the two readings is too great, the ECM determines the thermostat is stuck. In this case, the ECM
registers a fault code in its memory.
The thermostat monitoring sensor works as a Negative Temperature Coefficient (NTC) sensor. As temperature rises,
the resistance in the sensor decreases, as temperature decreases, the resistance in the sensor increases. With this
information, the ECM is able to monitor the performance of the thermostat. The normal operating parameters of the
thermostat monitoring sensor are as follows:
