The P0333 is a fairly straight forward code pointing to a problem with the Knock Sensor for Bank2. The sensor is located on the passenger's side of the engine, towards the bottom, at about the center of the engine block. For an image location view, click here: https://goo.gl/11Eccq . For the best access, remove the passenger's side front wheel and work through the wheel well. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the inspection check ok, replace the sensor. To replace, unplug the electrical connector and remove the mounting bolt from the center of the sensor. Turn-and-pull the sensor out of the engine.
