Is your 6.4L Powerstroke lacking power, running rough, or throwing EBP-related codes? The Walker Exhaust Backpressure Sensor restores precise exhaust pressure feedback to your ECM, enabling it to manage fueling, turbo operation, and emissions performance properly. When this sensor fails, your truck can experience sluggish acceleration, excessive smoke, and poor regen control. Replacing it with this direct-fit solution restores smooth performance, improved efficiency, and reliable drivability under load. Exhaust backpressure data is critical for engine control, especially in emissions-equipped diesels, making this a key fix for restoring proper operation.

Built to meet or exceed OEM specifications, this sensor uses high-quality metals and ceramic components designed to withstand extreme exhaust heat, vibration, and contamination. Engineered and tested for durability, it delivers stable and accurate signal output even in harsh diesel environments. With an OE-style connector and direct-fit design, installation is quick and hassle-free, restoring proper ECM communication and long-term reliability mile after mile.
