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:
Restores Ignition Timing Accuracy: Supports optimal fuel efficiency, performance, and emissions by correcting spark advance during knock conditions.
Detects Engine Knock: Monitors vibration frequencies to detect detonation and prevent pre-ignition engine damage.
OE Replacement Sensitivity: Calibrated to match factory frequency response and output for seamless ECU integration and spark control.
Exact OE Fit: Installs directly into original mounting locations using factory connectors and threads—no modifications required.
Built for Harsh Environments: Engineered to resist heat, vibration, and oil exposure for long-lasting signal reliability.
La livraison se fait en un temps record, malheureusement il y a eu un erreur de pièce, par contre un service très professionnel, facile d'accès et dans ma langue natale..... Le retour est accepté sans frais. Tout les professionnels dans le domaines de la mécanique savent que des erreurs survient aléatoirement au niveaux pièces un jour ou l'autre, pas très agréable mais la ou ce joue la qualité du service est le service après vente et je peux confirmé la compétence de l'équipe Parts Pionner... Merci à l'équipe
Toujours en attente du ticket de retour mais j'ai confiance dans leurs bref délais...
LB Mécanique générale vous remercie et aux plaisirs de refaire affaire ensemble....!
This was my first dealing here. Easy to browse the site,the ordering process was quick and straightforward and shipping was fast and flawless. 10 out of 10.
Parts were well packaged, came with all hardware needed for clips, anti rattle clips, as well as mounting hardware. I drove the car to have the car relearn piston positioning, and these are much more grippy than factory honda/acura pads and rotors, so I am really happy with them. I am surprised it only took 3 days for them to arrive after ordering them from Calgary to sw ontario. I have already recommended part pioneer and this brand of pads and rotors to my friends.
Parts came really fast and of good quality as I’ve been a licensed mechanic for over 25 years departure just as good or better than buying in your local parts stores
