Walker Products Exhaust Backpressure Sensors are OE Replacement components designed to monitor pressure within the exhaust system and provide critical data to the engine control module (ECM). This sensor plays a key role in managing Exhaust Gas Recirculation (EGR) function, turbocharger performance, diesel aftertreatment, and overall emissions control. The ECM uses this data to adjust boost levels, regulate EGR flow, and determine conditions for Diesel Particulate Filter (DPF) regeneration. A failed or drifting exhaust backpressure sensor can lead to check engine lights, EGR malfunction, loss of power, or increased emissions. Walker sensors are manufactured to meet or exceed OE specifications for pressure range, signal accuracy, electrical compatibility, and environmental durability. Each sensor is built with heat-resistant housings, high-quality diaphragms, and sealed electronics to endure prolonged exposure to soot, vibration, and thermal cycling in both gasoline and diesel applications. Designed for an exact OE fit, Walker Exhaust Backpressure Sensors install directly into the original mounting location and connect to the factory harness with no modifications required. Whether replacing a failed unit or addressing emissions-related drivability concerns, these sensors help restore system accuracy, protect engine components, and ensure compliance with emissions regulations.
Characteristics include:
Exact OE Fit: Designed for 100% compatibility with factory mounting locations and connectors—no wiring or modification required.
OE Replacement Calibration: Matches factory pressure range, voltage output, and signal response for seamless ECU integration.
Monitors Exhaust System Pressure: Provides critical pressure data to the ECU for EGR operation, turbo management, and emissions control.
Restores Emissions & Turbo Efficiency: Helps resolve drivability issues, fault codes, and performance loss caused by inaccurate pressure readings.
Engineered for Harsh Environments: Built to withstand high exhaust heat, soot, and vibration for long-term reliability in diesel and gasoline systems.

I love PartsPioneer. The rear-wheel Positive Plus pads and Genius rotors fit perfectly on my 2019 Subaru Forester. Excellent quality at a fair price. Highly recommended.
Thanks for catching an error in my order and righting it for me, complete with email to say so! This … is what customer service head and shoulders above, looks like !! Well done all !!
Service was great, appreciated the phone call to confirm the vehicle. Parts arrived quick. OEM fit. Will be ordering brakes as you can see by the picture. Very impressed.
I have bought this rotor on part pioneer for my Q3 and installed and used for over a week, they are amazing no squeaks no noises brakes have improved 110%. This rotors are the best so far I’ve always bought rotors and used in all three of my cars and so far these ones are the best that I have ever bought.
Thanks
