Walker 242-1355 Ignition Knock (Detonation) Sensor
Walker Knock Sensor OE Replacement
Walker 242-1355 is an OE replacement ignition knock sensor for gasoline engines that need accurate detonation detection and factory-style signal output. It monitors engine vibration so the ECU can adjust ignition timing in real time, helping reduce spark knock and related drivability concerns.
Compatible With Hyundai Elantra N, Kona N, Veloster N, Santa Fe, Santa Fe Sport, Sonata and Kia Sportage, Optima, Sorento applications that use this sensor style. The Sensor Only line from Walker focuses on direct-fit replacement parts built to match OE specifications.
Key Features
- Terminal type: pin
- Connector quantity: 1
- Connector shape: oblong
- Terminal quantity: 2
- Connector gender: female
- Terminal gender: male
- OE-style frequency range, sensitivity, and electrical output
- Heat- and oil-resistant construction for engine-block and cylinder-head environments
- Direct replacement for factory threaded sensor locations
Detailed Description
Walker Products part number 242-1355 is engineered to detect the resonant frequency associated with knock in the specific engine platform it serves. That precise signal allows the engine control unit to retard timing when detonation is detected, helping protect internal engine components and maintain stable ignition performance. This Walker Sensor Only replacement is built for direct installation using factory-style electrical terminals and OE fitment dimensions.
This part cross-references no listed aftermarket part numbers for the same application.
What It Helps Address
- Diagnostic trouble codes such as P0325 or P0330
- Audible spark knock or detonation under load
- Timing control issues caused by a failed knock sensor
- Reduced fuel economy related to incorrect ignition timing
- Drivability problems tied to inaccurate knock detection
Installation Notes
Install Walker 242-1355 in the original threaded sensor location and connect it with the factory-style plug. Verify connector shape, terminal count, and engine application before installation. Clear any stored fault codes after replacement and confirm proper operation with a scan tool if needed.
Fits 2022-2026 Hyundai Elantra N, N/A; 2022-2023 Hyundai Kona N, N/A; 2019-2022 Hyundai Veloster N, N/A; 2019-2020 Hyundai Santa Fe, N/A; 2011-2019 Hyundai Sonata, N/A; 2013-2018 Hyundai Santa Fe Sport, N/A; 2011-2022 Kia Sportage, N/A; 2011-2020 Kia Optima, N/A; 2016-2018 Kia Sorento, N/A.
Quality Assurance
Walker knock sensors are built to OE replacement standards for signal accuracy, fitment, and durability in demanding engine environments. Part number 242-1355 is designed to restore proper knock detection across the listed Hyundai and Kia applications.
