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

SOURCE: Chrysler 300 3.5 v6 Slight engine knock - oil always changed

I have a 2006 with a 3.5 (41,000 miles). No oil consumption but had the knock. Started as a slight knock and continued to get louder. My buddy works at the dealer and hooked me up. Chrysler knows about this problem, it's the rocker arm assembly coming apart. They have a new revised part to fix the problem. THEY NEED TO RECAL THIS.

How to prevent engine knock on 92 Ford Thunderbird Lx


The sensor helps to monitor the engine performace, and when it detects knock or pinging. It sends a signal to the PCM which in turn adjusts the timing and fuel ratio to reduce or eliminate it in those situations you have knocking. Low octane, bad gas, carbon deposits and heat will contribute to pinging. It's best to replace the sensor if you know it is faulty to avoid damage to the engine.

Valves clacking changed the oil pump and lifters but still clacking what could be the problem


Do you know what a knock sensor is ?
The knock sensor (KS) system enables the control module to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The control module uses the KS system to test for abnormal engine noise that may indicate detonation, also known as spark knock.
If the control module has determined that knock is present, it will retard the ignition timing to attempt to eliminate the knock. The control module will always try to work back to a zero compensation level, or no spark retard. An abnormal KS signal will stay outside of the noise channel or will not be present. KS diagnostics are calibrated to detect faults with the KS circuitry inside the control module, the KS wiring, or the KS voltage output. Some diagnostics are also calibrated to detect constant noise from an outside influence such as a loose/damaged component or excessive engine mechanical noise
Do you know what spark knock is or pinging ? EGR valve problem ! Is your oil pressure low ? do you have a gauge or a oil light ! If it where an oil pump problem the light would be lit ! Is your check engine light lit ? How many miles on the vehicle ? Timing chain an gears , jumped time !

How can I troubleshoot/resolve engine knock?


Sorry but you have a bad piston rod bearing or main bearing ! You won't have any indicators lit on the dash as this is a engine mechanical fault ! EGR - Knock sensor has nothing to do with this ! Take it to a shop an they will tell you the same thing .

Bad oil pump knock


ionMr. Hugo. what to what you do have is the viscosity of your engine oil. Most probably is either long mileage used engine oil and due to that oil mud built up inside the engine, in the oil pan and most likely close to the oil pressure pump filter reducing the suction and that is why you do have cold lifter knocking,as the engine oil that time is thicker and when it gets hot become thinner and lifters stopped knocking. My persona advise do flush the old engine oil using ( RESTORE MOTOR CLEANER ) pour it into the engine old oil,start the engine in idle and few times reving it for 40 minutes. Then drain it and renew the engine oil with new and recommended engine oil for your engine,by renewing the oil filter as well. Also in the new engine oil put also (RESTORE FRICTION REDUCER ) additive and run the engine.For next oil change please do it every 5000 km ( 3000 miles)

Is it true that a damaged knock sensor can slow down or make the car lose power while going uphill? Toyota Corolla VE 98


Yes it can. The knock sensor retards the timing due to irregular levels of octane in todays gasoline, to eliminate or reduce what is called a spark knock. A malfunction could cause your car to lose power when car is under a load or uphill due to pre detonation or constantly retarded spark to the engine. If not replaced it can cause engine damage or head gasket damage. Hope this helps.

Loud knocking coming from the bottom end and now loss of power sludge build up i have changed oil normal every 2500-3000 miles with synthetic and slick fifty.


the engine probably has a bad bearing in it.oil sludge can be caused by short trip driving,overheating,pluged crank case vent or pcv system not working.the power loss due to the computer retarding ignition timeing due to the knock sensor producing a signal from the engine knock.regardless an ongine ocerhaul or replacement is neede.
but first make sure that the bell housing bolts,torque converter bolts are all tight.
make sure the knock isnt from the catalytic converter
check for dents in the oil pan
check engine accessorys for noise such as water pump.power steering pump,alternator,a/c compressor.and all attachment bolts

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.

Engine knocking and oil lampe illuminated during idle


Change oil and filter. Use a synthetic blend oil, add 1/2 pint of marvel mystery oil, and drive for a short time, 30 minutes or so. If knock continues, the damage is already happened. Use only synthetic blend or synthetic oil in the 2.7 litre engine.
