A knock sensor is often located bolted on the center of the wall of the cylinder block Find the electric harness above the thermostat (usually located near the area where the radiator hoses meet the engine). It is usually a gray/black connector with two wires and a red cap.

2. Unplug this connector and fix a voltmeter that can measure more than 10 M ohms to the male connector.

3. Check the foremost terminal and ground the negative point out.

4. Check the voltmeter for continuity after turning the vehicle on. If there is a problem with this, you will need to replace the knock sensor.

5. Also, if your vehicle has run over 100,000 miles without replacing the knock sensor, it is best to get it changed.

6. You will also need to check for frayed wires to confirm a faulty sensor.

7. Another way to test the knock sensor is by striking the intake manifold above the knock sensor with a wrench, while the engine is running. Be careful not to strike the sensor. Hitting the intake manifold should result in a small change in the sound of the engine. If this does not occur your knock sensor is probably dead.

It will be easiest to find by getting under the truck and looking up at the engine. It will be a round sensor that screws into the side of the engine block. It will only have one or two wires going to it, usually just one. It is round and about 1 1/4 inches across. Not sure if it is on the driver or passenger side, but it should be pretty easy to find.

Under intake manifold on top of block,you need to remove intake to access sensors there are two of them you can't miss them when intake is off. After replacing sensors you need a new intake gasket.

Unfortunately, the knock sensor is located UNDER the intake. You have to pull the intake off. I had a mechanic do mine. He said its best to replace both because they both corrode. (2 sensors, intake gasket, labor ($250)
