Walker 242-1420 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for OE-Style Engine Control

Walker 242-1420 is an OE replacement ignition knock sensor built to monitor engine vibration and report detonation events to the ECU. It supports real-time ignition timing correction to help prevent spark knock, drivability concerns, and internal engine damage.

Walker Sensor Only products focus on direct-fit sensor replacement for vehicles that need accurate signal output and factory-style electrical connection. This Walker knock sensor is engineered for gasoline applications that require precise knock detection and OE-style performance.

Key Features

• OE replacement ignition knock (detonation) sensor
• Matched for frequency range, sensitivity, and electrical output
• Pin terminal design with 1 female connector and 2 male terminals
• Oblong connector shape for factory-style fitment
• Heat- and oil-resistant construction for engine bay conditions
• Direct installation into original threaded sensor locations

Detailed Description

Walker 242-1420 is designed to detect the resonant vibration pattern associated with engine knock so the ECU can adjust ignition timing as needed. That signal control is important on modern Ford and Lincoln engines where accurate detonation feedback helps maintain smooth operation and protect internal components. This part number is used in applications such as the Ford Bronco, Ford Bronco Sport, Ford Escape, Ford Explorer, Ford F-150, Ford Mustang, Ford Ranger, Lincoln Corsair, and Lincoln Nautilus.

The Sensor Only line is focused on replacement sensors that match OE specifications and connect using factory-style terminals. For buyers searching for a Ford F-150 knock sensor, Ford Mustang knock sensor, or Lincoln Corsair knock sensor, Walker 242-1420 provides the correct sensor-only solution for the listed applications.

This part cross-references no listed interchange numbers for the same application.

Common Issues This Sensor Can Help Resolve

• Knock sensor fault codes such as P0325 or P0330
• Erratic ignition timing caused by a failed knock signal
• Spark knock or detonation-related drivability problems
• Reduced fuel economy from incorrect timing correction
• Engine control issues caused by inaccurate vibration sensing

Installation Notes

• Install into the original threaded sensor location on the engine block or cylinder head, as equipped.
• Use the factory-style electrical connector with the correct pin and terminal orientation.
• Verify the connector shape and terminal count before installation.
• Clear diagnostic trouble codes after replacement and confirm proper ECU response.

Quality Assurance

Walker Products builds this knock sensor to OE specifications for fit, frequency response, sensitivity, and electrical output. The heat- and oil-resistant materials are selected for the demanding environment around the engine, supporting reliable knock detection in the listed Ford and Lincoln applications.
