Walker Products Ignition Knock (Detonation) Sensor P/N:242-1356

Keep your engine's ignition timing dialed in with the Walker Products Ignition Knock (Detonation) Sensor 242-1356. It drops in as a direct-fit replacement for the 2015-2016 Hyundai Genesis and 2016-2017 Kia K900, mounting in the left-side knock sensor location.

A knock sensor listens for the high-frequency vibrations of pre-ignition (detonation) in the engine block and sends that signal to the engine control module, which adjusts ignition timing to protect the engine. If a failed sensor is the cause of your trouble code or timing issues, this unit replaces it.

• Function: Detects abnormal combustion vibration and reports it to the ECM for timing correction.
• Position: Cataloged for the left-side knock sensor location on the listed applications.
• Application: Direct-fit replacement for the listed vehicles.

Signs this sensor may need replacing include a stored knock-sensor trouble code, an illuminated check engine light, or reduced timing performance. Diagnose the cause before replacing, as these symptoms can have other sources.

Interchange: Manufacturer part number 242-1356 (also 2421356).
