What Does the P0327 Lexus Code Mean?

A flat-type knock control sensor (non-resonant type) has a structure that can detect vibrations between approximately 5 kHz and 15 kHz. The knock control sensor is fitted onto the engine block to detect engine knocking. The knock control sensor contains a piezoelectric element that 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.
If the output voltage transmitted by the knock control sensor remains low or high for 1 second or more, the Engine Control Module (ECM) interprets this as a malfunction in the sensor circuit and stores a Diagnostic Trouble Code (DTC).
