Good Maintenance Practices:
- Thread the sensor into exhaust, before connecting the wires, to help prevent possible damage to the wire harness.
- Keep the wire harness away from hot surfaces.
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.
