Differential Pressure Sensor – Mopar (5149229aa)

Differential Pressure Sensor is an electrically controlled component in the engine or transmission management system. Because the module cross-checks it against other inputs, a fault here often surfaces as a code for a different circuit.

Replace the Differential Pressure Sensor when a value freezes or drops out intermittently, which usually means an internal fault rather than wiring. Wiggle-testing the harness while watching live data separates the two.

Reference number for the Differential Pressure Sensor: 5149229aa. It is filed under Sensors & Switches, and it is the number that has to match the part coming off the vehicle.

Genuine MOPAR part for the Differential Pressure Sensor. Where the manufacturer has superseded a number, the current reference is the one that ships.
