      Symptoms of a malfunctioning Knock Sensor: CHECK ENGINE LIGHT: Usually a faulty knock sensor will trigger the check engine light to flash on your vehicle's dashboard. Sometimes, using cheap gasoline causes detonation and triggers the power train module the engine's main control board to wrongly diagnose the knock sensor and send a false malfunction message through check engine light. Try filling your vehicle with a higher grade of gasoline, and if the light is still flashing, consult with a mechanic., NOISES: If the knock sensor is not working properly, you will likely hear sounds emitting from the engine. You may hear loud thumping noises that become louder over time. The noise is a result of fuel and air igniting inside the cylinder, instead of reaching the point of combustion., OTHER SYMPTOMS: There are several other symptoms indicative of a knock sensor problem. The vehicle will often shake or vibrate and misfire when the engine is started. The engine may emit strong exhaust and burning smells due to the detonation in the cylinders. Fuel economy is often affected, causing the vehicle to burn more gas than usual and requiring frequent fuel replenishment. Also, your vehicle may display acceleration problems, such as dragging, hesitation or jerking from the engine during speed increases.
