Product Description
An ACDelco GM Original Equipment Exhaust Temperature Sensor reports the
exhaust gas temperature to the engine control module, and is a GM-recommended
replacement for your vehicle’s original component. The temperature signal is
used by the control module to adjust fuel delivery and boost pressure to
protect the exhaust after-treatment components from overheating and keep them
operating efficiently. This original equipment exhaust temperature sensor has
been manufactured to fit your specific GM vehicle, providing the same
performance, durability, and service life you expect from General Motors.
