Generally the knock sensor would tell the computer to reboot or back off the ignition timing. So you could feel a loss of power even if there was no reason for the computer to change the timing.

This will not be the switch itself it will be the blower motor resistor itself.These vehicles have had a notorious tsb for these resistors doing this.This resistor is located right next to the blower motor on the evaporator box.It's on the pass front side right below the dash.I hope I could help...rate me accordingly

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.

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.

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.

2000 silverado knock sensor issue


I think it not real probable that the cause of your knock sensor code is the result of bad gas. However, I suppose it IS possible. Most knock sensor codes are caused by engine mechanical problems like bad pully bearings, loose timing chains, broken valve springs, collapsed valve lifters, etc. that would cause a "knocking" or "tapping" in the engine.

The next most probable cause would be damaged knock sensor wiring. I have fixed many that have had damage from rodents getting into the engine compartment and chewing on the wires. Depending on which engine your Silverado is equipped with, the knock sensor could be mounted between the cylinder heads in the valley under the intake manifold. Mice like it under there.

Then again, it all depends on WHAT KIND of knock sensor code you are getting. For 2000 Silverado there are 3 possible knock sensor codes: P0325, P0327, P0332. The diagnostics (and possible causes) change depending on which code you have.

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.

Where are the knock sensors located on a 2002 chevy silverado 2500hd 6.0 engine?


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.
