SOURCE: I recently changed both knock sensors and wiring harness on my 99 Lexus rx 300! I purchased the parts on ebay and they state (OEM PARTS) Check engine, P0330,

code p 0330 refers to knock sensor (KS)2 bank 2 ---circuit malfunction===causes wiring--KS---ECM
it is possible that in changing the harness there is a problem connection or the connection to ks2 is not correct ( not on properly)

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

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.

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

92 lexus es300 knock sensor


Need to remove the upper and lower air intake manifold.  There are two knock sensors for the front and rear pistons banks.  If you plan to do this yourself it is about 1 to 2 hours.  While you are at it, there is a short coolant bypass hose sitting in the same spot, replace it.  Another problem with the knock sensor is the wire harness used to connect the two knock sensors into one connection sometimes wears out and contacts the metal on the engine causing false signals to the ECM, so replace this cable also.
Just did this last summer on my 99 ES300.  Pretty easy.
