Check the Wiring to Sensor First for Opens , Then Listen for Any "NOISE' that the Sensor Could Be Picking up. Its Purpose is to DETECT Pre Ignition PING so it can Sygnal Computer to Change the Timing Accordingly.

Code p0325


P0325 Knock Sensor 1 Circuit Malfunction
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged.
The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.
Symptoms You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.
Causes A code P0325 most likely means one or more of the following has happened:
  • The knock sensor is faulty and needs to be replaced
  • There is a wiring short/fault in the knock sensor circuit

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.

Check engine light was on. Connected scan tool, got data below and cleared faults. drove car 5 miles, check engine stayed off. p0300 random multiple misfire detected p0325 knock sensor 1 circuit...


If the check engine light stayed off then that means that those errors are not present at this time. It is not un common to have intermittent faults but I would not preced any further until the light comes back on. Then re-scan the code see which are to begin diagnostics.

It does sound like the sensor may be bad, but you also need to check the wiring.
This information comes from:

Causes

A code P0325 most likely means one or more of the following has happened:

Possible Solutions
  • Check the resistance of the knock sensor (compare it to factory specs)
  • Check for broken/frayed wires leading to the sensor
  • Replace the knock sensor

A P0325 refers to the knock sensor electrical circuit, not the sensor itself! So check all wiring & connectors leading to the sensor, back to the PCM. Good luck, I found a good P0325 article here - http://www.obd-codes.com/p0325

The check engien light comes on once in ahwile and when that happenes the car looses power, i had it checked out and it was the knock sen....so i had it replaced, about two years ago ...yet the problem...


It is most likely a bad knock sensor location. You can sometimes find repositioning kits for the sensors because they tend to be too senitive. It is usually on the back under or on intake manifold by fuel rails
