P0334 Code: Knock Sensor 2 Circuit Intermittent (Bank 2)The knock sensor generates a low amount of electricity while the engine is running. A code P0334 will be stored if the PCM detects an unusual signal from knock sensor 2.
P0324 Code: Knock Control System ErrorThe knock sensor is part of the knock control system that includes its connector, wiring, and the PCM. Most sensors are attached to the engine block, cylinder head, or intake manifold. In most engines, there is a knock sensor for every cylinder bank. There are some engine designs that have
P0333 Code: Knock Sensor 2 Circuit High Bank 2The algorithms in the ECM/PCM are set up in such a way that spurious knocking noises not related to combustion are ignored.

P0326 Code: Knock Sensor 1 Circuit Range / Performance Bank 1A knock sensor is a one-wire or two-wire sensor mounted on a cylinder block, and it detects engine knocking. “Knock sensor 1” in this code refers to the first sensor (if there are two), while “bank 1” refers to the side of the engine with cylinder #1.
P0328 Code: Knock Sensor 1 Circuit High (Bank 1 )Knock sensors are devices that are used to detect engine knock. This sensor is typically a two-wire sensor, though there are some devices that only have one wire. The knock sensor receives a 5-volt reference and returns a signal to the PCM.
