Walker Products Ignition Knock (Detonation) Sensors are OE Replacement components that monitor engine vibrations to detect knocking or detonation events. These sensors are a critical part of the engine control system, allowing the ECU to adjust ignition timing in real time to prevent spark knock—a condition that can cause internal engine damage, reduced fuel economy, and drivability issues. Walker Knock Sensors are engineered to match OE specifications for frequency range, sensitivity, and electrical output. Each unit is tuned to detect the specific resonant frequency of knock in a given engine platform, enabling precise spark retard when knock is detected. Built from high-quality, heat- and oil-resistant materials, these sensors are designed to endure the harsh conditions of the engine block and cylinder head. With exact OE fitment, Walker Knock Sensors install directly into the original threaded locations and connect using factory-style electrical terminals. Whether addressing a fault code (e.g., P0325, P0330), correcting timing issues, or replacing a failed sensor, Walker Knock Sensors restore proper knock detection, improve engine safety, and support optimal ignition performance across a wide range of gasoline applications.
Characteristics include:
Exact OE Fit: Installs directly into original mounting locations using factory connectors and threads—no modifications required.
OE Replacement Sensitivity: Calibrated to match factory frequency response and output for seamless ECU integration and spark control.
Restores Ignition Timing Accuracy: Supports optimal fuel efficiency, performance, and emissions by correcting spark advance during knock conditions.
Built for Harsh Environments: Engineered to resist heat, vibration, and oil exposure for long-lasting signal reliability.
Detects Engine Knock: Monitors vibration frequencies to detect detonation and prevent pre-ignition engine damage.

Customer Reviews
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
Awesome parts, for a great deal, and the customer service is second to none, always willing to help, and they double check fitment to ensure you always get the right parts! Will definitely be ordering again.
