2012 GMC Sierra 3500 HD Exhaust Temperature Sensors

ACDelco GM Original Equipment Exhaust Temperature Sensors report exhaust gas temperature to the engine control module, and are GM-recommended replacements for your vehicle’s original components. The temperature signal is used by the control module to adjust fuel delivery and boost pressure to help protect exhaust after-treatment components from overheating and keep them operating efficiently. These original equipment exhaust temperature sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

EGT sensors frequently seize in the exhaust bung, making replacement difficult and damaging the bung. This Dorman OE FIX solution directly replaces the sensor and comes with a bung repair kit just in case.

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.
