Walker Products Exhaust Gas Differential Pressure Sensors are precision-engineered OE Replacement components designed to measure the pressure differential across the diesel particulate filter (DPF). This critical data is used by the engine control module (ECM) to determine the appropriate timing for regeneration cycles, reduce soot buildup, and maintain compliance with emissions standards. Walker sensors help detect clogging conditions early to prevent drivability issues and protect against costly engine derate events. Built to operate in the harsh exhaust environment, each sensor features a rugged construction that resists high temperatures, vibration, and soot contamination. These units are manufactured to meet or exceed OE specifications for pressure range, signal accuracy, and electrical performance. With exact OE fit and factory-matched connectors, installation is quick and seamless across a wide range of diesel applications. Trusted for light-duty and medium-duty diesel platforms, Walker Exhaust Gas Differential Pressure Sensors deliver accurate, reliable data for clean engine performance and long-term emissions system durability.
Characteristics include:
Supports Emissions Compliance: Helps detect DPF clogging and enables ECM-managed regeneration to avoid engine derate and costly repairs.
Precise DPF Monitoring: Measures pressure differences across the diesel particulate filter to ensure accurate regeneration and emissions control.
Built for Harsh Environments: Engineered with rugged materials that resist extreme exhaust temperatures, vibration, and soot exposure.
OE Replacement Design: Built to meet or exceed OE specifications for signal output, pressure range, and fit for consistent sensor reliability.
Exact OE Fit Installation: Designed for 100% OE fitment using factory-matched connectors and mounting points for quick, trouble-free replacement.

Overall rating: 4.9 / 5 from 594 reviews.
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
Renato
