Can't find knock sensor on chevrolet truck

knock sensor job is to smooth out the engine from knocking or pinging. meaning one of cylinders is not running well

Knock sensors located under the in-take, in-take will have to be remove to replace sensors.

knock sensors are under the intake manifold. Its not as bad as it looks. There is NO oil or antifreeze to mess with when removing the intake

Hello: The knock sensors are under the intake manifold.

There's two knock sensor's, and there under the in-take, on top og the engine, when the knock sensor detects a knock on the engine block, it will send a signal to your compute to adjust the engine timing.

The knock sensors are under the intake manifold, inside the valley cover. You have to remove the intake manifold in order to access them.

If all connections are good "dry, tight, no corrosion" then yes. It should be a defective sensor. These sensors are piezo sensors and create a voltage when sensing a knock. A bank refers to a side on a V style engine, 2 refers to the rear sensor on your bank 2. Bank 1 should be the side with cylinder #1 which should be the cylinder closest to you on one of the sides. So your looking for the rear sensor on the opposite side.

Knock sensors as a rule of thumb are positioned right beside a piston on the the block. It should be on the opposite side of the exhaust system. A knock sensor is actually a sensitive microphone or listening device. It listens to a piston performance under load. If it hears a knocking or pinging sound it will ****** the ignition timing and advance it again when condition changes. It would have a securing bolt in the middle which torqued to a certain spec and a single wire harness.

On the rear of the engine block in the back of the cylinder head.Some were put on the side of the cylinder head below the exhaust manifold.Remember: your vehicle also has a knock sensor module located in the PCM (computer housing)

There are 2 both located in the block..
