Genuine Cummins 2870024625 sensor used in diesel engine applications
The part number 2870024625 is a genuine Cummins sensor used in multiple engine and equipment systems. It is designed to measure specific parameters such as temperature or pressure within the engine environment. This component plays a critical role in maintaining engine performance, emissions compliance, and diagnostic reporting.
Understanding the purpose, application, and replacement guidelines for this sensor helps ensure accurate system operation and longevity of your engine.
Function of 2870024625
The 2870024625 sensor works as a real-time feedback device in diesel engines. It provides essential data to the electronic control module which uses the information to adjust engine parameters. The sensor helps optimize combustion, fuel delivery, and emissions control.
It is most often used in medium to heavy-duty engines where precision is required to maintain operational stability.
Common Applications
This sensor is used across multiple Cummins-powered systems. Typical applications include on-road trucks, generator sets, marine engines, industrial pumps, and construction machinery.
Its use varies slightly depending on the model of the engine but the core functionality remains consistent across platforms. Equipment manufacturers install this part to ensure that the engine receives accurate readings for better operational control.
Original Equipment Use
The sensor is an original equipment part. It is not a universal sensor and should only be used in systems that specifically require this part number.
Using the wrong sensor can result in incorrect data transmission to the control system. That may cause poor fuel economy, loss of power, and error codes related to emissions or engine health.
Always match the part number exactly before replacing any sensor in a Cummins engine.
Physical Characteristics
The 2870024625 sensor is compact and robust. It typically includes a sealed electrical connector, corrosion-resistant housing, and a precision sensing tip.
The outer shell is usually built from thermoplastic or steel materials suitable for high-heat environments. The connector features a lock mechanism to avoid disconnection due to vibration or movement inside the engine compartment.
Installation and Replacement
Replacing this sensor requires basic mechanical tools and an understanding of the engine layout. Follow proper service manual procedures. Shut down all power and ensure the engine is cool before handling the sensor.
Locate the old sensor by referencing the engine diagram. Remove the connector and unscrew the sensor. Carefully install the new sensor and ensure the connector is clean before attaching it.
It is recommended to clear fault codes using a compatible diagnostic tool after installation. This ensures that the new sensor is correctly recognized by the control system.
Symptoms of Failure
If the 2870024625 sensor begins to fail, the following symptoms may appear:
-
Inaccurate data readings on diagnostic tools
-
Check engine light or service warnings
-
Engine derating or reduced power mode
-
Fault codes related to emissions or temperature
Always inspect both the sensor and its wiring. Damage to the wiring harness or corrosion at the connector can cause similar issues.
Maintenance Tips
This sensor requires little to no maintenance when installed correctly. However, for best performance:
-
Check the connector for dirt or corrosion during routine inspections
-
Replace the sensor if the engine logs persistent fault codes
-
Avoid using aftermarket or remanufactured sensors unless verified
Sensors should not be cleaned using chemicals or abrasives as they may damage the internal elements.
Where to Purchase
Genuine 2870024625 sensors should be purchased from certified Cummins dealers, OEM suppliers, or trusted online parts distributors. Always verify the part number on the label before purchase.
Avoid buying from unknown sources as counterfeit sensors are common and can damage the engine control systems.
Technical Validation
Before installation, cross-reference the part with your engine’s manual. This confirms that it matches the engine configuration and software. Using unmatched sensors may lead to errors during operation or calibration.
Consult Cummins support or your service provider if any compatibility issues arise.
Final Insight
The 2870024625 sensor is a critical component used in Cummins engines for accurate diagnostics and real-time engine management. Proper installation, part verification, and timely replacement can prevent engine damage and reduce downtime.
