Walker 242-1363 Ignition Knock (Detonation) Sensor

Walker 242-1363 Ignition Knock Sensor

Walker 242-1363 is an OE replacement ignition knock sensor built to monitor engine vibration and detect detonation events. It helps the engine control unit adjust ignition timing in real time, supporting knock control on gasoline applications such as Chevrolet Silverado 1500 and GMC Sierra 1500.

Sensor Only OE Replacement

The Walker Sensor Only line focuses on direct-fit replacement sensors engineered to match OE frequency range, sensitivity, and electrical output. This Walker knock sensor uses a female connector with 1 connector opening, 2 terminals, an oblong connector shape, pin-style terminals, and male terminal gender for factory-style electrical connection.

• OE replacement ignition knock (detonation) sensor
• Engine vibration monitoring for spark knock detection
• Matches OE specifications for frequency range and sensitivity
• Heat- and oil-resistant construction for engine-block environments
• Direct-threaded OE fitment with factory-style terminal layout
• Walker 242-1363 for precise knock detection and timing control

Detailed Application Overview

This sensor is used to detect abnormal combustion noise so the ECU can reduce ignition advance when knock is present. For Silverado 1500 and Sierra 1500 applications, as well as Express 1500 and Savana 1500 platforms, Walker 242-1363 supports accurate detonation sensing where the original sensor has failed or set a fault code such as P0325 or P0330. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

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