Walker Products Ignition Misfire Sensors are OE Replacement components engineered to detect combustion irregularities by monitoring engine vibrations or crankshaft acceleration. These sensors help the engine control unit (ECU) identify which cylinder is misfiring, allowing for precise diagnostic action and fuel/ignition system adjustments. Accurate misfire detection is essential for maintaining emissions compliance, drivability, and preventing potential catalytic converter damage. Walker Ignition Misfire Sensors are manufactured to meet or exceed OE specifications for sensitivity, signal range, and electrical compatibility. Depending on the application, they may be integrated with crankshaft position sensors or mounted separately on the engine block or cylinder head. Built with vibration-resistant casings, sealed electronics, and durable connectors, these sensors are designed to withstand harsh under-hood environments including thermal cycling, oil contamination, and vibration from engine operation. With exact OE fit and form, each Walker sensor installs directly into the original mounting location and connects with the factory wiring harness—ensuring easy replacement with no reprogramming required. Whether resolving drivability concerns, addressing misfire-related DTCs, or supporting engine diagnostics, Walker Ignition Misfire Sensors help restore precise ignition monitoring and protect downstream emissions components.
Characteristics include:
Restores Emissions & Performance Control: Helps eliminate drivability issues, check engine lights, and power loss caused by misfire detection faults.
Exact OE Fit: Designed for 100% compatibility with factory mounting locations and electrical connectors—no modification required.
Detects Cylinder Misfires: Monitors crankshaft fluctuations or vibration patterns to identify combustion irregularities in real time.
Engineered for Harsh Environments: Built with vibration-dampening housings and sealed electronics to withstand heat, oil, and engine vibration.
OE Replacement Accuracy: Calibrated to match original sensitivity, frequency response, and signal behavior for seamless ECU integration.

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
