Walker 242-1356 Ignition Knock (Detonation) Sensor - Left

Walker 242-1356 Knock Sensor Overview

Walker 242-1356 is an OE replacement ignition knock sensor for gasoline engine management systems. 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, left, and 2016-2017 Kia K900, left, this Sensor Only line is built for direct replacement in the original threaded location. Walker 242-1356 is tuned for the frequency range and electrical output required for accurate knock detection.

Key Features

• OE replacement ignition knock (detonation) sensor
• Matches OE frequency range, sensitivity, and electrical output
• Factory-style fit for direct installation in the engine block or cylinder head location
• Heat- and oil-resistant construction for underhood conditions
• Spade terminal design with 1 oblong female connector and 2 male terminals
• Walker Sensor Only product line for direct-fit sensor replacement

Detailed Description

The Walker Sensor Only line focuses on direct replacement sensors that restore factory-style signal accuracy without changing the vehicle’s engine control strategy. This knock sensor is engineered to detect the resonant frequency associated with spark knock so the ECU can reduce timing advance in real time. For Hyundai Genesis and Kia K900 applications, that signal accuracy matters for protecting the engine and maintaining consistent drivability.

Part number 242-1356 is built with durable materials selected to withstand heat, oil exposure, and the vibration environment around the engine block. The factory-style connector and threaded mounting design support a straightforward replacement where the original sensor was installed. This part cross-references Walker Products 242-1356 for the same application.

What It Helps Address

• Knock sensor fault codes such as P0325 or P0330
• Audible spark knock or detonation under load
• Incorrect ignition timing response from the ECU
• Reduced fuel economy caused by timing retard events
• Drivability concerns tied to failed knock detection

Installation Notes and Tips

Verify the original sensor location before installation and match the left-side fitment for the listed vehicles. Inspect the connector, wiring, and mounting surface for corrosion or damage before connecting the new sensor. Use the factory threaded location and tighten to the vehicle manufacturer’s specification.

Quality Assurance

Walker knock sensors are manufactured as OE replacement components with specifications matched for frequency response, sensitivity, and electrical output. Part number 242-1356 is built to restore proper knock detection in the listed Hyundai Genesis and Kia K900 applications.
