Cummins X15 Temp Sensor 2024-2027: OEM 5654179

Precise Temperature Monitoring for Cummins X15 Engines (2024–2027)

What is it?
The Cummins X15 Temp Sensor (2024–2027), identified by OEM part number 5654179, is an engine sensor designed for Cummins X15 diesel engines produced from 2024 through 2027. This sensor detects critical temperature data — often from the exhaust or aftertreatment system — and transmits it to the engine control unit (ECU). The ECU uses this data to make informed decisions about combustion parameters, exhaust treatment, and emissions system behavior.

Why choose this Temp Sensor?
Built to Cummins’ original specifications for the X15 platform, this temperature sensor delivers reliable and accurate readings that the engine’s control systems depend on. When a temperature sensor fails or sends incorrect information, it can affect combustion timing, aftertreatment operation, and regeneration strategies, often resulting in system warnings or less efficient emissions handling. Using the correct OEM-specified sensor helps maintain consistent system feedback and improved overall engine coordination.

Key Benefits
✅ Designed for Cummins X15 engines (2024–2027)
✅ Provides accurate temperature feedback to ECU
✅ Helps support optimized combustion and emissions control strategies
✅ Direct replacement — no modifications needed
✅ Engineered for heavy-duty thermal environments

Applications
This temperature sensor is suitable for medium- and heavy-duty trucks, commercial vehicles, and industrial equipment powered by Cummins X15 engines built between 2024 and 2027. It’s ideal for long-haul tractors, regional freight rigs, vocational trucks, and other platforms where accurate thermal data is essential to efficient engine operation.

Installation Notes
Before servicing, ensure the engine and exhaust components have fully cooled to prevent burns or damage. Locate the temperature sensor in the designated port, disconnect its electrical connector, and remove the old sensor. Check the wiring harness and sensor mounting location for contamination or wear before installing the new unit. Install the replacement sensor and torque it to the manufacturer’s specifications, then reconnect the electrical harness. After installation, clear any stored fault codes and verify correct temperature readings using appropriate diagnostic procedures.

Final Thoughts
If your Cummins X15-equipped vehicle shows temperature-related fault codes, uneven combustion behavior, or emissions system irregularities, replacing a worn or failing temperature sensor with the correct OEM unit can help restore accurate thermal monitoring and smoother overall system performance. The Cummins X15 Temp Sensor (OEM 5654179) plays a crucial role in dependable engine and emissions system operation across varied duty cycles.
