Walker 242-1354 Ignition Knock (Detonation) Sensor - Right

OE Replacement Knock Sensor

Walker 242-1354 is a Sensor Only ignition knock sensor built for direct OE-style replacement 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 2015-2016 Hyundai Genesis Coupe, right; 2015-2016 Hyundai Genesis, right; and 2016-2017 Kia K900, right. The Walker Sensor Only line focuses on direct-fit electrical and mounting details for straightforward replacement service.

Key Features

• Ignition knock (detonation) sensor for engine vibration monitoring
• OE replacement design with frequency range, sensitivity, and electrical output matched to factory specifications
• Spade terminal type with 1 rectangle female connector and 2 male terminals
• Heat- and oil-resistant construction for engine-block and cylinder-head environments
• Direct threaded fitment and factory-style electrical connection
• Part number 242-1354 for service lookup and ordering

Detailed Description

Walker 242-1354 is engineered to detect the resonant frequency associated with knock in the supported engine platforms, allowing the ECU to respond with precise spark retard when detonation occurs. That control helps maintain proper ignition timing and engine protection in daily driving and under load. This knock sensor is a practical replacement when the original sensor has failed, when a diagnostic trouble code points to knock sensor circuit issues, or when timing control has become inconsistent.

For Hyundai Genesis Coupe, Hyundai Genesis, and Kia K900 applications, this Sensor Only part is built to install in the original threaded location and connect with the factory-style terminal layout. The Walker 242-1354 part number is a direct reference for technicians and parts buyers working on knock sensor service.

What It Helps Address

• Knock sensor fault codes such as P0325 or P0330
• Unstable ignition timing caused by inaccurate knock detection
• Engine pinging or spark knock under load
• Reduced fuel economy related to timing correction issues
• Drivability concerns tied to failed detonation sensing

Installation Notes and Tips

Verify the right-side location before installation and compare the connector shape, terminal count, and terminal gender to the original sensor. Clean the mounting surface and inspect the harness connector for corrosion or damage before connecting the replacement. Because knock sensors are mounted in a high-heat area, confirm the threaded bore and wiring route are in good condition during service.

Quality Assurance

Walker Products builds this knock sensor as an OE replacement component with specifications aligned to factory frequency response and electrical output requirements. The Sensor Only product line is focused on direct-fit replacement parts for emission control and engine management service.
