30530P8FA01 Knock Sensor — 1Pcs Keep engine performance safe and precise with a reliable knock sensor. The 30530P8FA01 Knock Sensor detects abnormal combustion (engine knock) and sends a signal to the engine control system so ignition timing can be adjusted. Replacing a faulty sensor restores proper timing control, helps prevent engine damage, and can stop knockrelated diagnostic trouble codes. Key benefits Protects the engine: detects knocking/pinging and enables the ECU to correct timing to avoid damage. Restores drivability: helps eliminate rough idle, hesitation, and loss of power caused by improper timing adjustments. Simple direct replacement: supplied as a single complete sensor (1Pcs) matching the 30530P8FA01 part identification for straightforward swapin service. Main features and attributes Function: Vibration/knock detection sensor that provides feedback to the engine control unit. Model/Part number: 30530P8FA01 (sold as 1Pcs). Form factor: Compact bolton sensor with an electrical connector for direct installation. Performance: Designed to detect engine knock vibrations and deliver prompt electrical signals for timing correction. Construction: Built for automotive engine bay conditions; engineered to withstand heat and vibration typical of combustion engines. Compatibility and fit Intended as a direct fit for applications that specify part number 30530P8FA01. Always verify the required part number for your vehicle or equipment before to ensure correct fit and function. Typical use cases a failed or intermittent knock sensor to clear knockrelated fault codes and restore normal ECU timing behavior. Install during engine maintenance or rebuilds to ensure accurate knock detection and safeguard engine components. Use as a diagnostic replacement when troubleshooting spark knock, pinging under load, or timingrelated drivability issues. Installation and recommendations with the engine cool and follow torque specifications from the vehicle service manual. Inspect wiring and connector for corrosion or damage; any wiring issues to ensure reliable signal transmission. After replacement, clear diagnostic codes and test drive to confirm knockrelated behavior is resolved. What to expect after replacement Reduced or eliminated engine knock/pinging. More consistent ignition timing and smoother performance under load. Resolution of related trouble codes when the sensor was the root cause. Note: This listing is for one (1) 30530P8FA01 Knock Sensor. Verify compatibility by matching the part number to your vehicle's service information before ordering.
