GMC EGR Valve Temperature Sensors

The temperature of various systems must be reported to the engine control module (ECM) as well as other operating system controllers in the vehicle. Coolant temperature, cabin temperature, exhaust temperature and ambient temperature are just a few systems reported by a temperature sensor. The temperature sensor is fed 5 volts by the systems computer, within the sensor housing will be a thermistor, or dropping resistor whose resistance value will change as the temperature surrounding it changes. Changing resistance in the circuit will change the volt signal at the processor indicating the current operating value.

GM Genuine Parts Exhaust Gas Recirculation (EGR) Valve Temperature Sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These sensors report the temperature of the exhaust gas flowing through the EGR valve, and are used by the engine control module to monitor the function of the EGR system. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
