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

The best way is to use a scan tool to clear the codes, that will turn off the light, also disconnecting the battery over night may work, but no completely sure about that, it varies from year to year.

SOURCE: knock sensor code, p0330

The knock sensors either work or they don't. When they do not, the light comes on. All that a knock senor is is a piezo crystal that vibrates at the frequency that is comparable to engine "knock", and sends that yes/no signal to the ECU. There are 2 knock sensors, and both are bolted to each side of the engine interior walls, under each cylinder head. You have to remove both of the intake manifolds to access the knock sensors and their wiring.
Price to pay? My flat rate book suggests 3.7 hrs to change both. 3.7 hrs times your local labour rate, plus the price of the 2 sensors and/or wiring, and the price for the gaskets for the upper & lower manifolds. Depending on your location, you could quickly spend over $500.00.

SOURCE: nissan xterra knock sensor

It's the valley of the engine underneath the intake manifold. It's about an $800 job because the top of the engine has to come off. However, unless you have a supercharged xterra it shouldn't effect performance. Also, the knock sensor will not trip the check engine light, as it does not indicate a primary problem, so if your light is on you should have another code that should be fixed first.

SOURCE: 98 Nissan Maxima - Check Engine Light, Knock Sensor

If the car is pinging you will set a knock sensor code.'
This comes from bad gas and running lean., You really need this professionally inspected to rule out the basics. I have seen alot of nissans with the knock sensor code stored but the light is still off.
Fill up the tank with high octane chevron and some techron injector cleaner and clear the light. If it stays off for a couple days then go get it inspected. Even if the code is stored it will still pass as long as the light is still off and the monitors have run.

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.

Code p0330 knock sensor does this affect the way it shifts if engine light is on


Possible but unlikely. Code p0330 refers to knock sensor(KS) 2 bank 2-circuit malfunction==causes --wiring --KS--ECM. Replace the KS. The engine light is telling you that there is a problem with sensors in the ECM and that is what will be affecting the performance . Shifting is the area of the TCM( transmission control module ) so have that checked out as well

What is ECU


The knock sensor is commonly located on the engine block and essentially listens for improper combustion when the engine is running. Engine knock, or spark knock, is the noise created when the combustion process is erratic or abnormal. Code p0330 indicates that the knock sensor has picked up a frequency outside of the factory-set frequency range for the combustion chamber. The computer uses information from the knock sensor to adjust the engine ignition timing to keep combustion within the safe zone of operation. In general, when the knock sensor code is set, the computer will put the engine into limp mode to help prevent engine damage.

GMC 4.3L DTC P0330 flashing MIL


P0330 - Knock Sensor 2 Circuit Malfunction (Bank 2)
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 P0330 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325.

Symptoms: You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.

Causes: A code P0330 most likely means one or more of the following has happened:
The "B" knock sensor is faulty and needs to be replaced
There is a wiring short/fault in the knock sensor circuit

Possible Solutions:
Check the resistance of the knock sensor on bank 2 (compare it to factory specs)
Check for broken/frayed wires leading to the sensor
Replace the knock sensor on bank 2


Hope helps.
