Detailed Description

Delphi TS30323 is a center-mounted EGT sensor used to monitor exhaust temperature in diesel emission control systems. Accurate exhaust gas data is critical for proper system operation, and Delphi calibrates these sensors to OE standards to help maintain correct readings and reduce repeat repairs. This part cross-references Standard Ignition ETS173 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in the emission control system
• Driveability issues tied to faulty EGT sensor input
• Regeneration or aftertreatment monitoring concerns caused by sensor failure
• Repeat repairs from inaccurate sensor calibration

Installation Notes and Tips

Confirm the connector style, terminal configuration, harness length, and center position before installation. Compare the original sensor location and connector layout on your Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, or Sierra 3500 HD to verify a proper match. Always inspect the wiring and exhaust routing for heat damage before replacing the sensor.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for consistent readings.
