Detailed Description

Delphi TS30478 is engineered for vehicles that rely on precise exhaust temperature data to manage emission system performance. The sensor uses a threaded nut mounting style, a black oval connector, and a 2-terminal blade interface for a secure electrical connection. Delphi validates and calibrates its sensors to OE standards, helping ensure the signal accuracy needed for dependable exhaust gas temperature monitoring on Ram 2500 and Ram 3500 models.

For buyers searching for a Ram 2500 EGT sensor or Ram 3500 exhaust gas temperature sensor, TS30478 provides a direct replacement option with the fitment coverage listed for 2019-2024 model years. The part number TS30478 is also useful when cross-shopping OE-style replacements for diesel emission control repairs.

What It Helps Address

• Faulty exhaust gas temperature sensor readings
• Emission control warning lights related to EGT monitoring
• Inaccurate exhaust temperature data sent to the engine control system
• Driveability issues caused by sensor signal errors
• Repeat repairs caused by out-of-spec sensor output

Installation Notes and Tips

Confirm the connector style, terminal count, and mounting type before installation. Inspect the harness routing and connector condition during replacement, and verify the sensor location against the vehicle service information for the specific Ram 2500 or Ram 3500 application. After installation, clear diagnostic trouble codes and verify that exhaust temperature readings are stable under operating conditions.

Quality Assurance

Delphi backs its sensor portfolio with OE development and product validation methods. Each sensor is tested and calibrated to OE standards to support accurate readings and reduce comebacks.
