Product Details

Walker Products Sensor Only line focuses on replacement sensors that match original equipment fitment and signal behavior. Part number 242-1416 is tuned to detect the resonant frequency associated with engine knock so the ECU can adjust ignition timing in real time. That helps the engine management system respond quickly when detonation is detected, supporting smoother operation and reducing the risk of spark knock-related damage.

This sensor is a direct replacement for select 2011-2016 Kia Optima and 2011-2015 Hyundai Sonata models. If you are diagnosing a knock sensor fault on a Kia Optima or Hyundai Sonata, Walker 242-1416 provides the OE-style sensor interface needed for accurate engine control feedback.

Common Issues This Part Can Address

• Knock sensor fault codes such as P0325 or P0330
• Erratic ignition timing caused by inaccurate knock detection
• Engine pinging or spark knock under load
• Reduced fuel economy related to timing correction issues
• Drivability concerns tied to failed detonation sensor input

Installation Notes and Tips

Install the sensor in the original threaded mounting location and connect it using the factory-style electrical terminal. No mounting hardware, gasket or seal, wiring harness, or thread sealer is included. Verify connector shape, terminal style, and engine application before installation. For best results, inspect the mounting surface and surrounding wiring for damage or corrosion before replacing the sensor.

Quality Assurance

Walker knock sensors are built to OE specifications for fit, frequency response, sensitivity, and electrical output. Part number 242-1416 is designed for dependable replacement performance in gasoline engine applications where accurate knock detection is required.
