Delphi TS30521 Exhaust Gas Temperature (EGT) Sensor

Delphi TS30521 Exhaust Gas Temperature Sensor

Delphi TS30521 is an Exhaust Gas Temperature (EGT) sensor built for accurate temperature monitoring in diesel emission control systems. It is a direct-fit style replacement for select Ram and Dodge Ram 2500 and 3500 applications, with OE-calibrated performance to support consistent sensor readings.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• OE-developed and OE-validated sensor design
• Calibrated to OE standards for accurate temperature readings
• Maximum temperature rating: 850
• 15.3 in. / 393 mm wiring harness length
• Black connector with square shape, 1 connector, 2 terminals
• Male connector and male terminal design with pin terminals
• Threaded nut mounting type

Detailed Description

The Delphi TS30521 EGT sensor is engineered for vehicles that rely on precise exhaust temperature feedback to manage emission control performance. This part number TS30521 is built with a threaded nut mount, square black connector, and OE-style electrical interface to match the original sensor layout on select 2007-2010 Dodge Ram 2500 and Dodge Ram 3500 models, plus 2011-2012 Ram 2500 and Ram 3500 trucks. Delphi tests and calibrates its sensors to OE standards, helping maintain accurate readings in demanding exhaust environments.

This part cross-references Standard Ignition ETS67 for the same application.

What It Helps Address

• Incorrect exhaust gas temperature readings
• Emission control warning lights related to EGT sensor faults
• Diesel exhaust monitoring issues on Ram 2500 and Ram 3500 trucks
• Sensor signal problems caused by heat exposure or connector wear
• Driveability concerns tied to faulty exhaust temperature data

Installation Notes and Tips

Verify connector shape, terminal count, and harness length before installation. Confirm the threaded nut mounting location and compare the original sensor routing on your Dodge Ram 2500, Dodge Ram 3500, Ram 2500, or Ram 3500 before replacement. Always inspect the exhaust bung area and wiring for heat damage, corrosion, or contamination that could affect the new 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 performance.
