Cummins 2007.5–2025 Ram 6.7L Cummins EGR Temperature Sensor (2872858)
Description
A failing EGR temperature sensor can trigger a Check Engine Light, cause emissions-related diagnostic trouble codes, and affect overall engine performance.
The Cummins 2872858 EGR Temperature Sensor is a genuine OEM replacement designed for 2007.5–2025 Ram 6.7L Cummins engines. Located in the EGR crossover pipe between the EGR cooler and EGR valve, this sensor continuously monitors exhaust gas temperature and sends that information to the ECM so it can properly manage EGR and emissions system operation.
Whether you're replacing a failed sensor, repairing the EGR system, or troubleshooting emissions-related fault codes, installing a genuine Cummins sensor restores factory accuracy and reliability.
Features
- Genuine Cummins OEM sensor
- Cummins Part Number: 2872858
- Fits 2007.5–2025 Ram 6.7L Cummins
- Direct OEM replacement
- Monitors EGR exhaust gas temperature
- Helps maintain proper emissions system operation
- Factory-calibrated sensor
- Plug-and-play installation
- OEM quality and reliability
Why Replace the EGR Temperature Sensor?
The ECM depends on accurate exhaust temperature data to properly control EGR operation and emissions functions.
When the sensor begins to fail, common symptoms may include:
- Check Engine Light
- Emissions-related fault codes
- Reduced engine performance
- Incorrect exhaust temperature readings
- Failed emissions diagnostics
- Intermittent drivability concerns
Replacing the failed sensor restores accurate temperature monitoring and helps the ECM properly manage the emissions system.
Glacier Tech Tip
Before replacing the EGR temperature sensor, inspect the electrical connector and wiring harness.
Heat, vibration, and damaged connector terminals can create symptoms similar to a failed sensor. If the connector is damaged or the terminals have lost tension, replacing only the sensor may not correct the problem. Always inspect the wiring before replacing electronic components.
Apply a small amount of high-temperature anti-seize to the sensor threads (avoiding the sensor tip) if recommended by the service manual to make future removal easier.
Why Choose Genuine Cummins Parts?
Temperature sensors operate in one of the harshest environments on the engine, where they're exposed to extreme heat, soot, vibration, and constant thermal cycling.
Genuine Cummins sensors are engineered to OEM specifications for proper calibration, durability, and long-term reliability. They install directly in the factory location and communicate correctly with the engine control module without the fitment or calibration issues sometimes found with aftermarket sensors.
Applications
Fits:
- 2007.5 Ram 2500 6.7L Cummins
- 2007.5 Ram 3500 6.7L Cummins
- 2008 Ram 2500, 3500, 4500 & 5500 6.7L Cummins
- 2009–2025 Ram 2500, 3500, 4500 & 5500 6.7L Cummins
Kit Contents
Includes:
- (1) Genuine Cummins EGR Temperature Sensor
- Cummins Part Number: 2872858
Important Notes
- Genuine Cummins OEM replacement sensor.
- Fits 2007.5–2025 Ram 6.7L Cummins applications.
- Located in the EGR crossover pipe between the EGR cooler and EGR valve.
- Direct plug-and-play replacement.
- Inspect the wiring harness and connector before replacing the sensor.
- Clear any stored diagnostic trouble codes after installation if necessary.
Common Failure Point
Years of exposure to high exhaust temperatures and thermal cycling can cause the internal electronics of the EGR temperature sensor to degrade. As accuracy decreases or the sensor fails completely, the ECM may no longer receive reliable exhaust temperature information, resulting in emissions-related fault codes and reduced system performance.
Replacing the sensor with a genuine Cummins unit restores accurate temperature monitoring and dependable operation.
