Knock Sensor: Detects engine knock and signals ECU to adjust ignition timing
This knock sensor is for Hyundai Veloster, Kia Rio, or Soul owners from 2010-2017 who notice poor acceleration or a check engine light. It's not just a replacement part—it's your engine's early warning system.
When the ceramic piezo crystal detects pre-detonation, it signals your ECU to adjust timing, preventing costly damage. You'll feel smoother performance and save on fuel. The included bracket makes installation straightforward, and it fits 1.6L, 2.0L, and 2.4L engines. Use a multimeter to test voltage output for peace of mind.
