2001. What are the probable causes of DTC P0333?

P0333 is a diagnostic trouble code (DTC) for "Knock Sensor 2 Circuit High Input (Bank 2)". and The P2273 diagnostic trouble code is an indication that the Bank 2 Sensor 2 oxygen (O2) sensor signal is stuck on rich. check more here https://toolsbible.com/knock-sensor-code/

If the PCM detects an excessively rich condition, DTC P0172 or P0175 sets.
Possible cause's , leaking fuel injectors , leaking fuel pressure regulator .
Possi GM CPI Leak Part 1 bleed down testing P0172 code

code p 0430 refers to catalytic converter system , bank 2 --efficiency below threshold=== causes --cat converter---wiring---HO2S 2
( that is the sensor in the exhaust manifold or pipe before the cat converter for bank 2--front bank)

That means that the knock sensor on the engine block has failed or the wiring or connections to it have failed.

That means the knock sensor or wires and connections to it are bad.

Hi there,
Code P0333: Knock Sensor 2 Circuit High Input (Bank 2)
Probable Causes:

1. Sensor or solenoid faulty
2. Connector terminal contact is damaged or corroded
3. Wire harness - Check harness for correct voltage, open, short to ground or short to voltage
4. Update control unit software - Check for the latest control unit update
5. Powertrain or Engine Control Module faulty

Note: ECM's rarely fail, so never replace the ECM, unless you are absolutely certain it has failed.


Hope this helps.

ECM has nothing to do those thing's . Probably not A BCM problem either . Did the Garage check for DTC'S - diagnostic trouble code's ?
DTC B3064 or B3069
DTC B3127
DTC B3128, B3133, or B3138
DTC B3132
DTC B3137
DTC B3272

Did they test the electrical circuit's for these componets ? Looking at a wirng diagram to see what if anything these have in common ,power feed , ground etc. maybe . What kind of garage did you take it to . Just to let you know ,replacing any module on your vehicle would need programming , dealer .

P0332 DTC Code - Knock Sensor 1 Circuit Low Input (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 on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.

You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms.

Potential causes for a P0332 DTC include (but are not limited to):
The knock sensor is faulty and needs to be replaced
There is a wiring open/short/fault in the knock sensor circuit
The PCM/ECM has failed
