Walker 242-1349 Ignition Knock (Detonation) Sensor - Left
Ignition Knock Sensor for OE Replacement
Walker 242-1349 is an OE replacement ignition knock sensor built to monitor engine vibration and detect detonation events. It helps the engine control unit adjust ignition timing in real time, supporting proper spark control on applications such as Hyundai Santa Fe, Kia Sorento, Kia Sedona, Hyundai Azera, and Kia Cadenza.
Walker Sensor Only products focus on direct-fit sensor replacement for factory-style service. Part number 242-1349 is engineered for the specified frequency range, sensitivity, and electrical output needed for accurate knock detection.
Key Features
- OE replacement ignition knock (detonation) sensor
- Factory-style oblong connector with 1 connector, 2 terminals
- Female connector / male spade terminal design
- Built with heat- and oil-resistant materials for engine-bay conditions
- Direct-threaded fitment for original sensor location
- Calibrated for knock frequency detection and timing correction
Detailed Description
This Walker knock sensor monitors vibration patterns from the engine block or cylinder head and sends the signal needed for the ECU to reduce spark advance when knock is detected. That function helps protect the engine from detonation-related damage while maintaining stable drivability and fuel economy. Part number 242-1349 is a direct replacement for vehicles that use a left-side or N/A sensor position, including Fits 2013-2018 Hyundai Santa Fe, Left; Fits 2011-2018 Kia Sorento, N/A; and Fits 2014-2018 Kia Sedona, Left.
Use this sensor when servicing a fault code, correcting ignition timing behavior, or replacing a failed knock sensor on the listed Hyundai and Kia applications. This part cross-references Walker Products 242-1349 for the same application.
Common Issues This Sensor Can Address
- Knock sensor fault codes such as P0325 or P0330
- Erratic ignition timing response under load
- Audible spark knock or detonation events
- Reduced engine performance caused by inaccurate knock detection
- Drivability concerns tied to a failed engine vibration signal
Installation Notes and Tips
Install the sensor in the original threaded location and connect it using the factory-style terminal layout. Verify the vehicle’s engine code, sensor position, and connector style before installation. For best results, inspect the harness and connector for corrosion, damage, or looseness before replacing the sensor.
Quality Assurance
Walker Products manufactures this sensor as an OE replacement component with specifications matched to the original application for frequency response, sensitivity, and electrical output.
