Walker 242-1328 Ignition Knock (Detonation) Sensor

Walker Sensor Only Knock Sensor 242-1328

Walker Products 242-1328 is an OE replacement ignition knock sensor for gasoline engines that rely on accurate detonation detection and spark control. It monitors engine vibration and sends a signal to the ECU so ignition timing can be adjusted when knock is detected.

Key Features

• OE replacement knock sensor for engine control systems
• Engineered for OE frequency range, sensitivity, and electrical output
• Pin terminal design with 1 female connector, square connector shape, and 2 male terminals
• Heat- and oil-resistant construction for engine block and cylinder head environments
• Direct-fit replacement for factory threaded mounting locations

Product Details

The Walker Sensor Only line focuses on direct replacement sensors built to match original equipment requirements. Part number 242-1328 is tuned to detect the resonant knock frequency for the supported engine platform, helping the ECU respond with precise spark retard when detonation occurs. That makes it a practical choice for restoring knock detection on Ford applications such as the F-150, F-250 Super Duty, F-350 Super Duty, E-350 Super Duty, and Mustang.

This part cross-references Walker Products 242-1328 for the same application.

Common Issues This Sensor Can Address

• Diagnostic trouble codes related to knock sensor performance, including P0325 and P0330
• Audible spark knock or detonation under load
• Incorrect ignition timing response from the ECU
• Reduced fuel economy caused by timing control issues
• Drivability concerns tied to failed knock detection

Installation Notes

Verify the connector style, terminal count, and threaded mounting location before installation. This sensor uses a square female connector with a pin terminal layout, so the harness connection must match the factory configuration. Clean the mounting surface and follow the vehicle service procedure for torque and electrical connection checks.
