SOURCE: 95 GMC Jimmy 4.3l W vin rough idle

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

How do I replace a knock sensor for a 1992 toyota camry v6 le


First, I would like to mention that most knock sensor codes are not caused by the knock sensors, but a mechanical problem with the engine. The knock sensors cannot differentiate between noises caused by mechanical problems like a bad pulley bearing, bad motor mount, noisy alternator bearings, etc. and spark knock. knock sensor codes are set when the computer has retarded the timing as far as possible to compensate for ignition ping (Spark Knock) and the noise still exists.

With that said, here are the instructions.

Remove the Intake Chamber assembly.
Disconnect Injector connectors.
Disconnect the heater hose from the Intake Manifold.
Remove the 9 bolts. 2 nuts, 2 plate washers and Intake Manifold assembly.
Remove right hand engine mounting stay and water outlet.
Disconnect the following hoses and connectors:
Radiator inlet hose.
Engine coolant reservoir hose.
Engine Coolant Temperature Sensor connector.
Engine Coolant Temperature Switch connector.
Ground strap connector.

Remove the 3 bolts and right hand mounting stay.
Remove the wire band.
Disconnect the water bypass hose from the inlet housing.
Remove the 2 bolts, 2 nuts, 2 plate washers and water outlet.
Remove the 2 gaskets.
Disconnect the Knock Sensor connectors.
Remove the Knock Sensors.

My 1997 nissan pathfinder p0325 code came up on the scanner, and I need to change my knock censor on the car. I do not known were this part is located on the engine


very familiar with this. it is down under the intake manifolds in the valley of the engine. it is a single wire connector. you must remove the manifolds to replace this item. parts will run you about $100 and take about 3-6 hours depending on your compentance. parts needed are 1. knock sensor 2. intake(upper and lower plenum gasket)set 3. coolant. make sure you drain your radiator prior to doing this as to not allow a bunch of coolant to drain into the cylinders and cause hydrolocking. if this happens you must remove the spark plugs and rotate the engine to spray out the liquid out of the cylinders then reinstall.

I can't find the location of the knock sensor on my 2005 chev silverado 1500 4x4 with a 5.3L engine.


Knock sensor replacement requires the removal of the intake manifold as the knock sensors are under it.

Knock sensor location


The knock Sensors are located under the Intake Manifold at the top of your engine. The top will have to be taken off along with the intake manifold. Knock Sensors in past silverados used to have a problem with leaking water that corroded the sensors from washing the engine. Most times when you go to replace the knock sensor you will have to replace both along with the wiring harness that includes the the gaskets the knock sensors are surrounded by. After that you have to check the resistance to make sure you dont have any problems and then reinstall all parts along with a new intake manifold gasket. A good mechanic can do this for you in a day and charge you around $400. If you try to go to some place like a chevy dealer you will pay over $800. This is from experience of just replacing mine 2 weeks ago.
