Walker 242-1418 Ignition Knock (Detonation) Sensor

Walker 242-1418 Ignition Knock Sensor

Walker 242-1418 is a Sensor Only ignition knock sensor built for OE-style replacement on select Ford and Lincoln applications. It monitors engine vibration so the ECU can adjust ignition timing when knock or detonation is detected, helping protect the engine and maintain smooth drivability.

Sensor Line Details

Walker Products Sensor Only components are focused on direct-fit sensor replacement without unnecessary extras. This knock sensor is engineered to match OE frequency range, sensitivity, and electrical output, with a factory-style square connector and spade terminals for a direct connection at the original mounting location.

• Part number: 242-1418
• Ignition knock (detonation) sensor for engine vibration monitoring
• OE replacement design with matched frequency range and sensitivity
• Square connector shape with 1 connector, male gender
• 2 terminals, spade terminal type, female terminal gender
• Heat- and oil-resistant construction for engine-block and cylinder-head environments
• Direct-fit sensor-only replacement for factory-style installation

Detailed Description

Walker 242-1418 is designed for gasoline engines that rely on accurate knock detection to control spark timing. When the sensor detects detonation, the ECU can reduce timing advance to help prevent spark knock, reduce drivability complaints, and limit internal engine stress. This part number is a practical OE-style replacement for Ford Escape, Ford Bronco, Ford Bronco Sport, Ford Edge, Ford Explorer, Ford Ranger, Ford Transit Connect, Lincoln Corsair, and Lincoln Nautilus applications listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Sensor Can Address

• Knock sensor fault codes such as P0325 or P0330
• Erratic ignition timing caused by inaccurate detonation feedback
• Spark knock or pinging under load
• Reduced fuel economy related to timing correction issues
• Drivability concerns tied to a failed engine knock sensor
