Delphi TS30479 Exhaust Gas Temperature Sensor

Delphi TS30479 is an exhaust gas temperature (EGT) sensor built for diesel emission control monitoring at the end of the particulate filter. It provides OE-calibrated temperature readings to support accurate exhaust system feedback on Ram 2500 and Ram 3500 applications.

Compatible With 2015-2018 Ram 2500 and 2015-2018 Ram 3500, after particulate filter.

  • Exhaust Gas Temperature (EGT) sensor for emission control monitoring
  • OE-standard testing and calibration for accurate temperature readings
  • Maximum temperature rating of 850
  • Black connector with oval shape, female connector and female blade terminals
  • Threaded nut mounting for secure installation at the end of the particulate filter
  • Wiring harness length: 241 mm / 9.3 in

Detailed Product Overview

The Delphi TS30479 is designed for exhaust temperature measurement where precise feedback is needed to manage diesel aftertreatment performance. Delphi validates its sensors to OE standards, helping maintain consistent signal output for the engine control system. This part cross-references Standard Ignition ETS122 for the same application.

Fits 2015-2018 Ram 2500, after particulate filter. Fits 2015-2018 Ram 3500, after particulate filter. Use TS30479 when replacing a failed EGT sensor on Ram diesel applications that monitor exhaust temperature after the particulate filter.

Common Issues This Sensor Can Address

  • Fault codes related to exhaust gas temperature sensor performance
  • Incorrect exhaust temperature readings at the particulate filter outlet
  • Aftertreatment system monitoring errors
  • Diesel emission control warning lights
  • Driveability concerns caused by inaccurate exhaust temperature feedback

Installation Notes and Tips

Install TS30479 at the specified after particulate filter location and verify the connector style, terminal count, and harness length before replacement. Inspect the mating connector and wiring for heat damage or corrosion, since EGT sensors operate in high-temperature exhaust environments. Confirm the sensor position matches the vehicle service location before clearing diagnostic codes.

Quality Assurance

Delphi sensors are developed and validated to OE standards, with calibration checks performed to support accurate readings and reduce repeat repairs. TS30479 is part of Delphi’s sensor portfolio for emission control and engine management applications.
