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

Did you reset the system ( clear the codes )? if so check that you are firing and or getting spark at all cyclinders. also check the wire to he knock sensor as they have a tendancy to get brittle and break inside. Good luck

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.

3.3l. Where is the knock sensor located?


this isn't a simple repair job, the knock sensor must be replace, I would also make sure that this IS the knock sensor that is the issue here otherwise if you replace and clear the codes the same issue will appear again, sometimes the engine computer will throw a code that is correct but misinterpreted which I believe might be your case,If you have a knock sensor code on any Nissan (in my experience) replacing the knock sensor will not fix it. The knock sensor detects unwanted engine vibrations, such as miss fires. So if you have a knock sensor code first check your spark plugs, are they in proper condition? (if not replace them). Next quest vans are known for clogging fuel injectors so i would recommend running a can of sea foam injector cleaner.

faulty aftertreatment outlet, ....... knock sensor, and check coolant temp sensor,if it is faulty it will cause a rich condition that can throw misleading codes. knock sensors often fail and throw code when no other fault is present. good luck and happy motoreing!

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.

I have an 02 jeep liberty stalls after warm and is throwing multiple knock sensor codes p0325, p0330 help


P0325, P0330 are both knock sensor codes that are detected by your ECU. Considering that you are showing both codes indicates that your model trim level is either "Limited" or "Renegade" that will have a knock sensor for 2 banks (V6). Knock sensor errors will change the timing of your engine ignition and can lead to a drop in performance or worse, lead to engine stalling in order to save other components of your engine.
The common solution to remove knock sensor codes is to have the sensors replaced by an authorized mechanic; sometimes shorted electrical leads to the sensors are also a cause for the codes. Replacing the knock sensors will remove the prompting of P0325, P0330 and expect to find another fault as engine stalling is not always present with knock sensor error codes.
Hope this helps.

Would knock sensor codes cause my 2000 lexus rx300 to act like it's not getting enough fuel and the overdrive to not work?


knock sensors are significant sensors for timing advance. if the engine is knocking then the computer will retard the timing thinking that it is pinging and you can lose well over 50% power. sometimes the sensor picks up other vibrations and creates timing problems even if the engine itself is not at fault.
