Walker 242-1347 Ignition Knock (Detonation) Sensor - Front

Walker 242-1347 Knock Sensor Overview

Walker 242-1347 is a sensor-only ignition knock sensor built for OE replacement use on select Hyundai and Kia applications. It monitors engine vibration and sends the signal the ECU uses to adjust ignition timing when detonation is detected.

Compatible With 2015-2017 Kia K900, front, and select Hyundai Equus, Genesis, and Kia Borrego applications listed below.

Key Features

• OE replacement ignition knock (detonation) sensor
• Engine vibration monitoring for knock detection and spark timing correction
• Engineered to match OE frequency range, sensitivity, and electrical output
• Heat- and oil-resistant construction for engine-block and cylinder-head environments
• Factory-style electrical connection with 1 oblong female connector and 2 male spade terminals
• Sensor-only design for direct replacement service

Product Details

Walker Sensor Only line focuses on direct-fit replacement sensors that match original electrical and mounting requirements. Part number 242-1347 is tuned for the resonant frequency of knock in the specified engine platforms, helping the ECU respond quickly when detonation is present. That makes it a practical choice for diagnosing knock sensor fault codes, restoring timing control, and maintaining proper engine protection on Hyundai Equus, Hyundai Genesis, Kia K900, and Kia Borrego vehicles.

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 concerns
• Reduced fuel economy tied to timing correction issues
• Engine protection concerns from delayed knock response

Installation Notes

• Install into the original threaded sensor location.
• Use the factory-style connector for the listed applications.
• Verify the engine platform and harness configuration before ordering, especially on Hyundai Genesis and Kia Borrego applications noted with long harness requirements.
• Confirm the connector style and terminal layout match the original sensor before installation.

Quality Assurance

Walker Products builds this knock sensor as an OE replacement component with specifications matched to the original frequency range, sensitivity, and output requirements for the listed vehicles.
