P0330 ? How two clear this flat - Cars & Trucks

egr IS DEAD FIX EGR VALVE FIRST.
EGR DEAD CAUSES PING, HEARD OR NOT IT IS THERE.

MOST CARS THIS OLD THE VALVE IS BAD, OR JAMMED
OR IS PACKED UP FULL IN CARBON OR WORSE THE WHOLE
EGR PATH IS CARBON BLOCKED.

KNOCK 2 SENSOR LOSE? OR WIRES TO IT WRECKED.

When the engine "knocks" there is an excessive amount of NOx that is released. When trouble code P0330 is set, this means that the knock sensor 2 in Bank 2 is not operating properly.

I use this website all the time:
https://www.obd-codes.com/p0320
https://www.obd-codes.com/p0330
https://www.obd-codes.com/p0420
https://www.obd-codes.com/p0430

Now the art is knowing how to interpret, the P0320 and P0330 can set off your P0420 and P0430 oxygen sensor codes. I would address the P0320 and P0330 first and probably the O2 sensor stuff will probably go away. If your car is knocking, rough idle, loses power, etc. then the 300 codes make sense and you have issues. It could also be two separate issues were damaged wiring on the knock sensors and then a damaged catalytic converter. I've got a car that constantly throws up 420 and 430 codes because the catalytic converter got dinged up from running something other.

I wonder if these two codes are related. P0330 could be due to a bad Knock Sensor which might affect the timing thereby causing issues with air/fuel ratio i.e. P1130

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

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.

Have the same problem on my 2001 Sienna with 184k miles. Knock sensor is the p0330 or p0325 code. Here is a walkthrough of the fix:
