Product Details: The Dorman Exhaust Gas Temperature Sensor ensures you are Ready for the Road Ahead™, being engineered to determine the temperature of the exhaust gases leaving the engine. This data is then transferred to the engine control unit (ECU). These data points assist the ECU in making necessary adjustments to the air-fuel mixture and other parameters. EGT sensors often get stuck in the exhaust bung, which can make replacing them difficult and potentially harm the bung. This Dorman OE FIX remedy directly replaces the sensors and comes with a bung repair kit, just in case. Dorman has a distinguished reputation in the heavy duty truck and trailer aftermarket, manufacturing a variety of parts for a complete repair. Through advanced engineering, Dorman successfully checks into today’s most common failures to figure out the why, ultimately delivering modern solutions that not only match OEM parts, but solve known issues.
