Description
This is an aftermarket engine oil pressure sensor for Cummins L10, M11, N14, and ISM diesel engines. The 3-pin sensor mounts in the main oil gallery (9/16″-18 thread) and feeds the ECM the analog signal used for low-oil-pressure warnings, derate logic, and oil-pressure gauges. Direct replacement for Cummins 4921487, 3080406, 3071575, 3072491, 3075273, and 3654108.
Signs You Need a New Oil Pressure Sensor
- Check-engine or low-oil-pressure light with no actual loss of pressure
- Erratic or stuck oil-pressure gauge reading
- Engine derate or no-start condition with oil-pressure-circuit fault codes
- Oil leak or weeping at the sensor port

Applications
This oil pressure sensor fits the following Cummins engines:
- Cummins L10 (mechanical and Celect)
- Cummins M11 (Celect, Celect Plus)
- Cummins N14 (Celect, Celect Plus)
- Cummins ISM (1998–2010)
Representative trucks using these engines:
- Kenworth W900 / T800 / T600 with L10, M11, N14, ISM
- Peterbilt 379 / 378 / 357 / 386 with L10, M11, N14, ISM
