No , a knock sensor doesn't make any noise , it listens for knocks and sends a signal to the PCM - engine computer . The PCM will retard ignition timing if the knock sensor picks up a engine knock . You best bet would be to take your vehicle to a qualified repair shop and have it checked out , before you spend money needlessly !

Knock Sensor contains no moving parts and can not make any noise. It only detects noise in the engine block to allow the engine control computer to make adjustments as needed.

SOURCE: knock sensor

The knock sensor threads into the side of the cylinder block.

  1. Disconnect electrical connector from knock sensor.
  2. Use a crow foot socket to remove the knock sensors.
INSTALLATION
The knock sensor threads into the side of the cylinder block in front of the starter.

  1. Install knock sensor. Tighten knock sensor to 10 Nm (7 ft. lbs.) torque. Over or under tightening effects knock sensor performance, possibly causing improper spark control.
  2. Attach electrical connector to knock sensor

What is code p0325 on 98 accord


Code 325 is for a knock sensor failure.
The sensor looks for spark knock and if that happens the engine computer slows down spark timing.
The problem could be the sensor, the wiring, or something other than spark knock the sensor is finding. A bad valve or rod knock can mirror the spark knock traits.

What can cause knock sensor to get bad on 2007 ford edge


Well the knock sensor does not make any noise. It senses the vibration in the engine if there is a spark knock to let the computer know to slow down the spark timing.
You probably have a weak piston or lifter or rod bearing making the noise.

2001 crown vic leaks oil and makes knocking sound when i accelerate, what can this be and please dont say rod knock


Can be several things. I want to say spark knock. Don't remember if your engine came with a Knock sensor.

Also stretched timing chain or weak timing chain tensioner. Another term to look at is "valve rattle". This would give you closer to a machine gun sound than other things.

My dodge stratus knocks when i accelerate what could it be?


Is the knocking coming from inside the engine or does it sound more like something external. Could be a rod knock or as simple as sensor. take a hose the you can hold and pin point where the noise is coming from.

My 01 has a bad knocking noise what does this mean?


it means that you need to research either a different car, or a different engine for this car. A loud knocking noise indicates a connecting rod is loose, and your engine has little to no time left before the rod or endcap breaks, completely messing up your engine, and making it very difficult to change. If you must drive it, drive it slow, and be super gentle with the gas...like you're driving on ice. If it's more of a ticking noise, that could be a lifter, but a loud hollow sounding knock is a rod. You may also have a check engine light showing up on the dash from the knock sensor.

Loud engine knock sounds like theconnecting rods in a 3.5L v-6 2002 trooper


If the engine knock is coming from deep inside the engine, the I agree, the rod is knocking.
If the sound is coming from closer to the top, it could be a valve lifter or push rod you are hearing. This isn't as bad, they last longer and synthetic oil or oil treatment helps.
If this doesn't happen all the time, if it's occasional or you hear a pinging noise, you could just have a bad knock sensor.

Knocking noise


If it is coming from the top of the motor, I would say it is a lifter tapping. If the sound is coming from the lower end of the motor I would say you have a rod knocking. If it is alifter you can replace just that lifter, if it is the rod I would consider a rebuild.
