The Hyundai/Kia 39250-2E000 Knock Sensor is a critical engine component designed to detect pre-ignition or "knocking," allowing the Engine Control Unit (ECU) to adjust timing and prevent engine damage. [1]
For the 2018–2021 Hyundai Kona and Tucson, using a genuine OEM part is highly recommended to ensure the sensor communicates correctly with the vehicle's Knock Sensor Detection System (KSDS) software
Key ConsiderationsCompatibility: This part is primarily for the 2.0L Nu engine. If you have a 1.6L turbo model, you may require the 39250-2B000 variant instead. Always verify your VIN at a site like Genuine Hyundai Parts before buying.Installation: The sensor is typically located under the intake manifold. Due to the labor involved in reaching it, many mechanics recommend sticking with the Genuine OEM version
