Delphi TS30515 Exhaust Gas Temperature (EGT) Sensor - After Particulate Filter, Catalytic Converter Rearward or Middle of Particulate Filter

Delphi TS30515 Exhaust Gas Temperature Sensor

The Delphi TS30515 is an exhaust gas temperature (EGT) sensor built for diesel emission control systems that rely on accurate temperature feedback. It is a direct-fit style sensor for select Chevrolet Silverado HD and GMC Sierra HD applications, including after particulate filter, catalytic converter rearward, and middle of particulate filter locations.

• Exhaust Gas Temperature (EGT) sensor for emission control monitoring
• OE-calibrated for accurate temperature readings
• Maximum temperature rating: 850
• 15.7 in. / 404 mm wiring harness length
• Black oval connector with 1 connector, 2 terminals, male connector and terminal ends
• Threaded nut mounting type for secure installation
• Position-specific fitment for after particulate filter, catalytic converter rearward, or middle of particulate filter applications

This part cross-references Standard Ignition ETS233 for the same application.

What this sensor helps address

• Incorrect exhaust temperature readings from a failing EGT sensor
• Diesel emission system warning lights tied to sensor signal faults
• Aftertreatment monitoring issues in particulate filter and catalytic converter zones
• Driveability problems caused by inaccurate exhaust temperature data
• Diagnostic trouble codes related to exhaust gas temperature monitoring

Installation notes and quality assurance

Verify the sensor position on your vehicle before ordering, since this part is position-specific. Match the connector style, terminal count, and harness length to the original sensor, and confirm the threaded nut mounting location during replacement. Delphi sensors are developed and validated to OE standards and tested for calibration accuracy to support consistent readings in emission control systems.

Part number TS30515 is also referenced as a replacement for OE-style applications where precise exhaust temperature measurement is required. Delphi TS30515 provides a technical replacement option for Silverado HD and Sierra HD diesel exhaust monitoring systems.
