Swap out the faulty barometric pressure sensor in your 2001-2005 GM 6.6L Duramax LB7/LLY with a Walker 225-1219 from XDP. The barometric pressure sensor measures barometric pressure through changing voltage and sends this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered.

Barometric pressure sensors can fail over time as the sensor can clogged by contaminants. The repetition of extreme heat and cold, known as "heat cycling", also breaks down internal circuitry. Issues typically arise from high mileage along with faulty wiring or damaged connectors. Normally your vehicle's check engine light will illuminate on your dash telling you there is a code in the computer that you need to read by a repair shop. You can also tell if your vehicle symptoms such as poor acceleration, engine ping or misfire, bad fuel economy, car surges or dies, or your vehicle won't start at all. Walker Products sensors are 100% programmed and tested. Walker Products works continuously to stay current on all OE design changes, TSBs, and improvements to the OE design to make the best part for your vehicle.
