Delphi TS30517 Exhaust Gas Temperature (EGT) Sensor - Exhaust Manifold

Exhaust Gas Temperature Sensor Overview

Delphi TS30517 is an exhaust gas temperature (EGT) sensor for the exhaust manifold on select Chevrolet Silverado 2500 HD and Silverado 3500 HD, as well as GMC Sierra 2500 HD and Sierra 3500 HD models. It provides OE-standard calibration and accurate temperature readings for diesel emission control monitoring.

Key Features

• Exhaust Gas Temperature (EGT) sensor for exhaust manifold mounting
• OE-developed and OE-validated sensor design
• Calibrated to OE standards for accurate temperature measurement
• Black oval connector with 2 terminals
• Threaded nut mounting type for secure installation
• Wiring harness length: 15.6 in. (400 mm)
• Maximum temperature rating: 850

Detailed Description

Delphi TS30517 is built for emission control systems that rely on precise exhaust temperature data. This EGT sensor is positioned at the exhaust manifold and uses a male oval connector with a threaded nut mount for a direct OE-style service replacement. Delphi validates and calibrates its sensors to OE standards, helping maintain accurate readings in demanding exhaust environments. This part cross-references Standard Ignition TX350 for the same application.

For 2017-2023 Chevrolet Silverado 2500 HD and 2017-2023 Chevrolet Silverado 3500 HD applications, as well as 2017-2023 GMC Sierra 2500 HD and 2017-2023 GMC Sierra 3500 HD applications, TS30517 supports exhaust temperature monitoring where precise sensor feedback is required. The Delphi TS30517 part number is commonly searched by buyers looking for an exhaust manifold EGT sensor replacement with OE-level fit and calibration.

What It Helps Address

• Faulty exhaust gas temperature sensor readings
• Emission control warning lights related to exhaust temperature monitoring
• Incorrect exhaust manifold temperature feedback to the engine control system
• Driveability issues caused by inaccurate sensor data
• Service replacement needs for worn or damaged EGT sensors

Installation Notes and Tips

• Verify the connector shape, terminal count, and exhaust manifold position before installation.
• Inspect the harness routing and connector condition during replacement.
• Confirm the vehicle application by year, make, and model before ordering Delphi TS30517.
• Use the OE-style mounting location and secure the threaded nut properly during service.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and tested to OE standards for accurate readings. That calibration process supports consistent performance in emission control applications and helps reduce repeat repairs.
