Walker 242-1358 Ignition Knock (Detonation) Sensor

Walker Sensor Only Knock Sensor 242-1358

Walker 242-1358 is an OE replacement ignition knock sensor for gasoline engines that rely on accurate detonation detection and spark timing control. It uses a 2-terminal, female rectangular connector with spade-style male terminals for factory-style electrical connection.

The Sensor Only line from Walker focuses on direct-fit replacement sensors built to OE specifications for frequency range, sensitivity, and electrical output. This helps the engine control unit respond quickly when knock is detected, which is important for Mitsubishi Lancer, Mitsubishi Outlander, and Mitsubishi Outlander Sport applications that use this sensor configuration.

Detailed Description

Walker 242-1358 monitors engine vibration and sends a signal to the ECU when knock or detonation is present. That signal allows ignition timing to be adjusted in real time, helping reduce spark knock that can lead to drivability problems, reduced fuel economy, and internal engine damage. The sensor is tuned to the resonant frequency expected for the application, which supports accurate knock detection on the listed Mitsubishi platforms.

Walker’s Sensor Only product line is built for OE-style replacement service, with electrical output and sensitivity matched to factory requirements. This makes 242-1358 a practical choice when replacing a failed sensor or diagnosing a knock sensor fault on a 2008-2011 Mitsubishi Lancer, 2008-2011 Mitsubishi Outlander, or 2011 Mitsubishi Outlander Sport. 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 inaccurate knock detection
• Spark knock or detonation-related drivability issues
• Reduced fuel economy from timing being held back
• Engine protection concerns tied to failed knock sensing

Installation Notes and Tips

Install Walker 242-1358 in the original threaded sensor location and connect it using the factory-style electrical terminal layout. Confirm connector shape, terminal count, and mounting style before installation. For best results, inspect the harness and mounting surface for corrosion, damage, or contamination before fitting the new sensor. Fits 2008-2011 Mitsubishi Lancer, N/A. Fits 2008-2011 Mitsubishi Outlander, N/A. Fits 2011 Mitsubishi Outlander Sport, N/A.

Quality Assurance

Walker designs this knock sensor to OE specifications for fit, sensitivity, and electrical output, with materials selected to withstand heat and oil exposure in the engine block area.
