Question about 2003 Kia Rio
On 2003 Kia Rio the knock sensor is located under the intake manifold and must be changed from underneath the car. If you remove the oil filter it is directly above it and is in clear view once the oil filter is out of the way. The connector plugs in behind the intake manifold air breather on the top side. If you remove the air breather cover it will help you get to it. I wish I had someone tell me where it was instead of looking for it for over 2 hours. It is simple after you find it.

Take off the air cleaner assy and on the back of the engine by the fire wall under the exhaust manifold you will see a wire coming up going to a connector thats the knock sensor one bolt that holds it on the engine and unplug it your done.

Did you delete the code ? Maybe it wasnt the knock sensor but the wiring to it. When we get a code we check all that is involved, wiring, connector, corroded connector terminals, then we test the sensor. If there is a fault in the wiring and or connector, this will set a code for the sensor indicating the need for a proper dignosis.
