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:
Detects Engine Knock: Monitors vibration frequencies to detect detonation and prevent pre-ignition engine damage.
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.
Restores Ignition Timing Accuracy: Supports optimal fuel efficiency, performance, and emissions by correcting spark advance during knock conditions.
OE Replacement Sensitivity: Calibrated to match factory frequency response and output for seamless ECU integration and spark control.
Excellent quality and fast shipping!
I’m very happy with my purchase from Pioneer Parts. The brake rotors arrived quickly, were well packaged, and the quality looks excellent. The fit and finish are great, and everything matched the description for VW Jetta 2013 TDI,Great service, fast delivery, and good-quality parts. I would definitely order from Pioneer Parts again!
Highly recommended! 🚗🔧⭐⭐⭐⭐⭐
The rotors and pads were perfect. A little disappointed the the front pads didn't come with new hardware, but the rear ones did. Would have been 5 star had the front hardware been included. Delivery was fast, and parts were exact.
Looks and feels great once installed. Sliders were loose but the pads were so tight in them even with lube I had to push/work them in. So that being said they did not slide. I would have had to grind down the tabs, which I didn't want to do. Eventually I made them fit. Wear gloves with these semi metallic pads as the will leave slivers in your skin. A great product so far, no rattles or stickiness....recommended for volts and other like gm vehicles.
Quality product from a quality supplier! I have ordered plenty of parts online in my life. This is the first time ever I had an actual person connect with me and confirm that the parts I was ordering were indeed the correct ones I needed for my vehicle. Was actually very impressed that they didn't want to ship until it was all verified to be correct, top notch! Will definitely be ordering through them for any of my future parts needs!
After a couple months these "coated" rotors developed so much rust in the drilled holes and slots. Not really impressed with the quality but they do stop the car I guess.
The service great and the parts are also great the people contacts you if you made wrong selection of the wrong part and that's what the people need less returns and les hassle every body wins thumps up
The shipping is super fast, the rotors and pads are packaged well, the customer service is helpful, everything looks good. Parts Pioneer is doing a great job.
Parts came on time and were correct. I have the brakes installed already and they are working good. Sway bar end links not installed yet, but appear good.
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.
Terrible customer service and misleading shipping information. I ordered brake calipers to be delivered to Newfoundland. When checking out it said it would arrive by Sept 3rd. When I got my tracking code it has changed to Sept 8th and said it was shipped from Alberta. I purchased these parts from an Ontario company! I had to reschedule my service appointment to the 9th. They still have not arrived so I have to purchase the calipers locally for twice the price and Parts Pioneer only offered me a 15% refund. No option to return them without having to pay the shipping myself. Unbelievable! Do not trust their shipping times if the parts are for a time sensitive repair.
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 !!
