sensor is commonly located on the engine block and essentially listens
for improper combustion when the engine is running. Engine knock, or
spark knock, is the noise created when the combustion process is erratic
or abnormal. Code p0330 indicates that the knock sensor has picked up a
frequency outside of the factory-set frequency range for the combustion
chamber. The computer uses information from the knock sensor to adjust
the engine ignition timing to keep combustion within the safe zone of
operation. In general, when the knock sensor code is set, the computer
will put the engine into limp mode to help prevent engine damage.
