Product Description
The CUMMINS 3930318 OEM THROTTLE POSITION SENSOR (TPS) is a genuine Cummins replacement sensor designed for 1994-1998 Dodge Ram 5.9L Cummins 12-valve diesel engines. This sensor monitors throttle position input and communicates accelerator demand to the engine and transmission control systems for proper drivability and shifting performance.
A failing TPS or APPS sensor can cause erratic throttle response, dead pedal symptoms, poor automatic transmission shifting, surging, inconsistent idle behavior, and diagnostic trouble codes. Replacing worn or malfunctioning sensors with genuine Cummins OEM components helps restore accurate throttle signal operation and dependable drivability.
Cummins OEM sensors are engineered to factory specifications for proper calibration, connector fitment, and long-term reliability in towing, daily driving, and heavy-duty diesel applications.
