Description

Get a Walker 274-1025 Differential Pressure (DPS) Sensor from XDP and replace the non-functioning DPS sensor in your 2014 GM 6.6L Duramax LGH/LML. The Differential Pressure Sensor monitors the performance of the Diesel Particulate Filter (DPF). The sensor operates by measuring the exhaust gas pressure upstream and downstream of the vehicle's DPF. By monitoring the pressure difference between these two points, the saturation level of the Particle Filter can be determined, and the vehicle's ECU can interpret the data to determine when to inject Diesel Exhaust Fluid (DEF) for regeneration.

Like many engine or exhaust components, the DPS has a limited life and will require periodic replacement. Common causes of Differential Pressure Sensor failure can occur from contamination, clogging, damaged electronics from intense engine heat, or vibration damage from prolonged exposure in the engine compartment. Symptoms of failing Differential Pressure Sensor may include excessive DPF regeneration cycles, engine will not start or starts poorly, detonation or misfire, excessive fuel consumption, lack of engine power, and a check engine light.
