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). ⚠ WARNING: Cancer and Reproductive Harm –

| FAQ – Answer 1 |
Yes. If the EGR temperature sensor malfunctions, it can cause cylinder temperatures to rise, which can cause engine ping or knock. This is an indicator that there is a problem with the combustion process. Any problem that results in engine ping or knock should be tended to as soon as possible, as engine knock can cause serious engine damage if left unchecked. |
