Walker 242-1444 Ignition Knock (Detonation) Sensor

OE Knock Sensor for Hyundai and Kia

Walker 242-1444 is a Sensor Only ignition knock sensor built as an OE replacement for gasoline engines that need accurate detonation detection. It monitors engine vibration so the ECU can adjust ignition timing quickly when knock is present, helping protect the engine and maintain stable drivability.

Compatible With 2020-2026 Hyundai and Kia applications including Santa Cruz, Tucson, Santa Fe, Sonata, Sorento, and Sportage. The Walker Sensor Only line focuses on direct-fit replacement sensors engineered for factory-style electrical connection and OE-style signal output.

Key Features

• Ignition knock (detonation) sensor for engine vibration monitoring
• OE replacement design with frequency range and sensitivity matched to original specifications
• Factory-style fitment for threaded sensor locations
• Blade terminal design with 1 oblong female connector and 2 male terminals
• Built with heat- and oil-resistant materials for engine bay conditions
• Walker 242-1444 supports precise spark timing correction when knock is detected

Product Details

Walker Products 242-1444 is engineered to detect the resonant frequency associated with knock in the specified engine platform, allowing the ECU to respond with real-time spark retard. That makes this sensor a direct replacement choice when diagnosing knock sensor faults, timing irregularities, or drivability concerns tied to detonation control. If you are replacing a failed sensor on a Hyundai Santa Cruz, Hyundai Tucson, Hyundai Santa Fe, Hyundai Sonata, Kia Sorento, or Kia Sportage, this part number provides OE-style electrical output and direct installation into the original threaded location.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Addresses

• Knock sensor fault codes such as P0325 or P0330
• Engine pinging or spark knock under load
• Incorrect ignition timing response from the ECU
• Reduced fuel economy caused by detonation-related timing changes
• Drivability problems linked to a failed knock sensor

Installation Notes and Tips

Verify the connector style, terminal count, and threaded mounting location before installation. Walker 242-1444 uses a blade terminal layout with one oblong female connector and two male terminals, so matching the factory harness is important. Clean the mounting surface and inspect the wiring for heat damage or corrosion before connecting the new sensor.

Quality Assurance

Walker knock sensors are built to OE replacement standards with materials selected for heat and oil resistance in engine-block and cylinder-head environments. The Sensor Only line is tuned for factory-style signal accuracy and direct-fit replacement performance.
