Walker Manifold Absolute Pressure Sensor With Pigtail 01-02 GM 6.6L Duramax LB7

Is your truck lacking power, surging under load, or throwing boost-related codes? The Walker Manifold Absolute Pressure (MAP) Sensor with Pigtail is a complete solution that fixes both the sensor and the wiring, two of the most common failure points, at the same time. This sensor measures intake manifold pressure and sends that data to your ECM so it can properly calculate fuel delivery, boost, and engine efficiency. When either the sensor or the connector fails, you can experience poor acceleration, misfires, bad fuel economy, or even a no-start condition. Replacing it with this Walker full-service kit restores accurate boost readings, smooth performance, and reliable drivability, whether you're towing or daily driving. Built for durability in harsh engine environments, this Walker MAP sensor is manufactured with high-quality, OE-matched materials that withstand extreme heat, pressure changes, and vibration. The included pigtail harness, butt connectors, and heat shrink allow you to create a secure, weather-tight connection, eliminating issues caused by brittle or corroded factory wiring. Its precision internal components are engineered for accurate pressure measurement and stable signal output over time. Fully tested to meet OE specifications for fit, form, and function, this kit delivers long-lasting reliability and a complete repair solution for demanding diesel applications.
