Walker 242-1088 Ignition Knock (Detonation) Sensor
Ignition Knock Sensor for OE-Style Engine Control
Walker 242-1088 is an OE replacement ignition knock sensor built to monitor engine vibration and report detonation events to the ECU. It is engineered for direct replacement on select Hyundai and Kia applications, including Hyundai Elantra, Sonata, Tucson, Kona, Veloster, and Kia Forte, Soul, Optima, Seltos, and Forte5 platforms.
Walker Sensor Only products focus on the sensing element and factory-style electrical connection needed for accurate knock detection. Part number 242-1088 is tuned for the resonant frequency, sensitivity, and electrical output expected by the original engine management system.
Key Features
- OE replacement ignition knock sensor for gasoline engine management systems
- Engineered to detect knock and detonation events in real time
- Matched frequency range, sensitivity, and electrical output
- Heat- and oil-resistant construction for engine block and cylinder head environments
- Direct-fit threaded mounting and factory-style electrical terminal connection
- Sensor Only line for applications requiring the sensing component and harness connection
- Part number 242-1088 for easy catalog and service identification
Detailed Description
Walker 242-1088 is designed to restore accurate knock detection when the original sensor has failed or when the engine control system needs a direct OE-style replacement. The sensor monitors vibration at the engine block or cylinder head and sends a signal that allows the ECU to adjust ignition timing immediately when spark knock is detected. That response helps protect internal engine components and maintain stable drivability.
This part cross-references Standard Ignition KS425 for the same application. It is a direct replacement choice for many Hyundai Elantra, Sonata, Tucson, Kona, and Veloster models, as well as Kia Forte, Soul, Optima, Seltos, and Forte5 vehicles. Use part number 242-1088 when searching for the correct knock sensor for these fitments.
What It Helps Address
- Knock sensor fault codes such as P0325 or P0330
- Retarded or unstable ignition timing caused by a failed sensor signal
- Audible spark knock or detonation under load
- Reduced fuel economy from incorrect timing correction
- Drivability concerns tied to inaccurate engine vibration feedback
