• OE-calibrated and tested to support accurate temperature readings
• Maximum temperature rating: 850
• Threaded nut mounting type for exhaust pipe installation
• Black oval connector with 1 connector, 2 terminals, male connector and terminal ends
• Wiring harness length: 159 mm / 6.2 in
• Fits exhaust pipe position applications

Detailed Description

Delphi TS30518 is engineered for exhaust gas temperature monitoring where precise sensor feedback matters for diesel emission control performance. Delphi validates and calibrates its sensors to OE standards, helping maintain accurate readings in demanding exhaust environments. This part number, TS30518, is listed for 2017-2023 Chevrolet Silverado 2500 HD and Silverado 3500 HD, plus 2017-2023 GMC Sierra 2500 HD and Sierra 3500 HD applications. This part cross-references Standard Ignition TX351 for the same application.

For buyers searching for a 2017-2023 Chevrolet Silverado 2500 HD EGT sensor, 2017-2023 GMC Sierra 3500 HD exhaust gas temperature sensor, or Delphi TS30518 replacement sensor, this unit matches the listed exhaust pipe position and connector configuration.

Vehicle Fitment

• Fits 2017-2023 Chevrolet Silverado 2500 HD, exhaust pipe position.
• Fits 2017-2023 Chevrolet Silverado 3500 HD, exhaust pipe position.
• Fits 2017-2023 GMC Sierra 2500 HD, exhaust pipe position.
• Fits 2017-2023 GMC Sierra 3500 HD, exhaust pipe position.

What It Helps Address

• Faulty exhaust gas temperature sensor readings
• Diesel emission control warning lights related to EGT monitoring
• Incorrect exhaust temperature data sent to the engine control system
• Sensor failure from heat exposure in the exhaust pipe
• Driveability issues tied to inaccurate exhaust temperature feedback

Installation Notes and Tips

Install the sensor at the exhaust pipe location specified by the vehicle application and verify the connector style before replacement. Confirm the harness length, threaded nut mounting, and terminal layout match the original sensor on the vehicle. For best results, inspect the surrounding exhaust components for heat damage, corrosion, or wiring wear before completing the repair.

Quality Assurance

Delphi sensors are developed with OE-focused validation methods and tested and calibrated to OE standards for accurate readings. That process supports consistent performance in emission control applications such as the Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD.
