Where is the knock sensor on a 1.3 Hyundai accent?

Answer 1

You can find the knock sensor on the rear side of the engine block (the side facing the firewall not the radiator). It is placed just a little bit below two of the three antifreeze plugs. It is held in place by only one bolt. It might be a little difficult to reach it because of the coolant inlet pipe that connects to the water pump. You have to put your car on ramps or jackstands and look up to see it. If you crawl under the car from the front and look up it is the cable coming down from the second intake on the manifold. In order to gain access to remove it there is a bracket thatsupports the intake that you have to remove, there are two bolts on the intake itself and one on the bottom. The sensor is located just right of center
