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/
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 #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 DTC. This P0327 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0328, P0329, P0330, P0331, P0332, P0333, and P0334.
Check engine light on ? What code ? There are many different (DTC'S) - diagnostic trouble codes that can set for knock sensors ! There all don't mean that you replace the sensor .
DTC P0324: Knock Sensor (KS) Module Performance
DTC P0325: Knock Sensor (KS) Circuit Bank 1
DTC P0326: Knock Sensor (KS) Performance
DTC P0327: Knock Sensor (KS) Circuit Low Bank 1
DTC P0328: Knock Sensor (KS) Circuit High Bank 1
DTC P0330: Knock Sensor (KS) Circuit Bank 2
DTC P0332: Knock Sensor (KS) Circuit Low Bank 2
DTC P0333: Knock Sensor (KS) Circuit High Bank 2
The knock sensor (KS) system enables the control module to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The sensors are located below each cylinder head on the engine block. The KS produces an AC voltage signal that varies depending on the vibration level during engine operation. The control module adjusts the spark timing based on the amplitude and the frequency of the KS signal. The control module receives the KS signal through 2 isolated signal circuits. The control module learns a minimum KS noise level at idle and uses calibrated values for the rest of the RPM range. The control module should monitor a normal KS signal within the noise channel.
Knock Sensor Replacement - Bank 1
Remove the exhaust manifold lower heat shield. Refer to Exhaust Manifold Lower Heat Shield Replacement.
Disconnect the engine wiring harness electrical connector (1) from the bank 1 knock sensor (2).
Loosen the knock sensor bolt and remove the knock sensor.
Knock Sensor Replacement - Bank 2
Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
Remove the engine oil filter. Refer to Engine Oil and Oil Filter Replacement .
Lower the vehicle.
Disconnect the engine wiring harness electrical connector (2) from the bank 2 knock sensor (3).
Loosen the knock sensor bolt and remove the knock sensor.
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

P0333 - Knock Sensor 2 Circuit High Input Bank 2. The knock sensor is attached to the cylinder block. It senses engine
knocking using a piezoelectric element. A knocking vibration from the
cylinder block is sensed as vibrational pressure. This pressure is
converted into a voltage signal and sent to the Powertrain Control
Module or Electronic Control Module.
The code is triggered by an excessively high voltage from the sensor is sent to Powertrain Control Module or Electronic Control Module.
Possible Causes: - Knock sensor circuit short to GND. - Knock sensor circuit short to PWR. - Knock sensor circuit open. - Damaged knock sensor. - Powertrain Control Module
Possible Solutions: - Repair or resecure harness or connector - Replaced knock sensor
code p1111 is system pass code p0333 is knock sensor 2 high input (bank 2) code p1643 is can link engine control module/transmission control modual circuit/ network also see if your car has a fuel pump shut off switch also other safety features on cars to protect against damage trans and oil fluid pressure also ckeck your neutral safety switch
