Knock Sensor 39250-2G000 for Hyundai Sonata Tucson 2.0L 2.4L 2010-2015
The Knock Sensor 39250-2G000 is a precision-engineered internal engine monitoring component designed to detect abnormal combustion pressure and piston knocking in your Hyundai vehicles. By identifying detonation events early, the sensor sends immediate feedback to your ECU, allowing it to adjust ignition timing and prevent catastrophic internal damage. When this part fails or degrades, drivers frequently encounter hesitation during acceleration, noticeable engine pinging, poor fuel economy, and persistent check engine warnings. Installing this exact OE-equivalent assembly restores factory-calibrated tuning, ensuring reliable cold starts, smooth power delivery, and long-term engine protection.
Benefits & Practical Tips- Bolt-On Compatibility: Designed to match original mounting threads and connector pins, enabling a straight swap without splicing wires or drilling.
- Restored Fuel Mileage: Consistent ignition timing keeps air-fuel mixing efficient, which gradually improves gallons-per-mile once the sensor resumes active monitoring.
- Installation Advice: Disconnect the battery negative terminal before unplugging the sensor harness. Use a torque wrench to avoid stripping the aluminum engine block threads during reassembly.
