Description
PAI 730387 engine oil pressure sensor for Paccar MX-11 and MX-13 diesel engines (2008–2018 generations). A direct replacement for Paccar 2127356PE and 2041678PE, this 4-pin circular sensor uses an M14x1.5 thread and reports oil-rail pressure to the engine ECU for low-oil-pressure protection and gauge feedback.
Signs You Need a New Oil Pressure Sensor
- Erratic or sticky oil pressure gauge reading
- Active fault codes for oil pressure circuit (e.g., SPN 100)
- Low-oil-pressure warning lamp with verified-normal pressure on a mechanical gauge
- Oil seepage at the sensor body or connector
