Code P0333 2009 Toyota Camry Description
A knock sensor is fitted onto the engine block to detect engine knocking. The knock sensor contains a piezoelectric element which generates a voltage when it becomes deformed. The voltage is generated when the engine block vibrates due to knocking. Any occurrence of engine knocking can be suppressed by delaying the ignition timing.
