No a knock sensor can not make a misfire. Check the coils, plugs and fuel pressure .The random misfires are cause the knock sensor to throw the code.

Hi, the indication is that your computer is not receiving a good signal from the knock sensor. Recommend you check the connector on the sensor and the wire. Also make sure the sensor isn't loose in the block. If those look good, you may want to just replace the sensor. A new one is $30 at autozone. Without the knock sensor signal, the computer will default the ignition timing toward a less fuel efficient value. The sensor looks like the picture below and is mounted in the engine block. You may have 2 knock sensors--one on each side of the engine. Sorry, but I could not find a good picture of the location. I will keep looking for one, though.

This condition may be the result of corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity. This condition is more apparent on vehicles in which customers frequently wash the engine compartment. Replace the rear bank knock sensor and build a dam (wall) around the sensor using RTV to divert water away from the sensor. Also, check for corrosion on the connector plug. Visually inspect the wiring going to the Rear Bank Knock Sensor for damage. After you have replaced the sensor, and checked for damages, have the code reset and see if it comes back.

You have two knock sensor's, both sit under the in-take magifold on top of the engine, you will have to remove injector rail and in-take.

knock senso is at the rear of the engine near the bell housing

Did they replace the knock sensor?Check the wire going to the sensor(knock).Look for a bare place hiting up against something ,grounding it out.Make sure the plug to knock sensor is good.And make sure it is making a good connection,Knock sensors also ground a part of the computer to feed back imformation.This connection is a must,the truck will not perform at all,stumble,miss,and carry on.Sometimes even backfire.If they did not replace the knock sensor,replace it with high quality sensor from NAPA,or oem from dealer.This sensor has to be made perfect,no room for inperfection.The knock sensor is easy to replace,they just screw in a hole in the block.When removing the sensors,nothing will come out such as oil or water,this is a dry threaded hole.It is a bell shaped sensor.If you don`t know which sensor is bad,purchase one.replace one,and if there is no change,replace the other side with the old sensor you just took out,it will be a good one.I hope this helps you,Let us know if it does.

If you have someone scan it with a scan tool that gives you data stream they can tell you exactly what cylinder is doing it. You might have a bad coil or wire.

Check out the Knox sensor & or the Blue wire going to it if it is Grounded , the timing will not Advance, Knox sensor is there to detect knock then it grounds if it catches a Knock to Prevent
