How does this replacement sensor affect engine performance and diagnostics?

A functioning knock sensor helps the engine control unit detect abnormal combustion events so ignition timing adjustments can be made. Replacing a defective sensor can clear knock-related fault codes, improve drivability, and help the ECU return to normal timing strategy.

• Restores correct knock detection to help prevent pinging under load
• Allows ECU to resume optimal timing adjustments
• Reduces the chance of misfires or limp-mode triggers tied to sensor faults
