★ Top Answer
In a 2014 Kia Optima, the knock sensor is situated on the side of the engine block beneath the hood. Its role is to identify any unusual knocking sounds within the engine and notify the driver. The sensor transmits data on each engine vibration to the car's main ECU. The ECU is programmed to distinguish between normal bumps and potentially problematic vibrations. If the vibrations fall within the specified range, the ECU will detect knocking and warn the driver. Replacing a defective knock sensor typically costs between $180 and $210.
