Code P0328 2011 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.
What are the Possible Causes of the DTC P0328 2011 Toyota Camry?
- Faulty knock sensor
- Knock sensor circuit poor electrical connection
- Knock sensor harness is open or shorted
- Faulty Engine Control Module (ECM)
