05093112AA Fuel Rail Pressure Sensor for Dodge Ram and GM Diesel

This high-pressure fuel sensor monitors fuel pressure in a compatible diesel injection system. It converts the measured pressure into an electrical signal for the engine control unit, supporting monitoring of fuel delivery and management of rail pressure and injection. The sensor must correspond to the original component reference, electrical connection, threaded fuel-system connection and engine configuration.

Supplied as a new aftermarket replacement single sensor, it is intended for the documented diesel applications when the original sensor identification agrees. The application table retains the vehicle models, engine designations and specific years listed in the manufacturer cross-reference catalogue. Year coverage is shown for each vehicle rather than being extended across the whole brand or engine family. The associated catalogue references are provided for identification and comparison. A one-year warranty is provided.
