Code P0327 2004 Infiniti G35 Description
The P0327 code in a 2004 Infiniti G35 indicates a Knock Sensor Circuit Low Input Bank 1 error. This means that the engine control module (ECM) has detected a lower than normal voltage signal from the knock sensor in Bank 1 of the vehicle's engine. The knock sensor is a crucial component that detects abnormal vibrations or knocking in the engine, which can be a sign of pre-ignition or detonation. When the knock sensor detects these vibrations, it sends a signal to the ECM to adjust the ignition timing to prevent engine damage.
Common Causes of P0327 2004 Infiniti G35
- Faulty knock sensor
- Wiring or connector issues in the knock sensor circuit
- Corrosion or damage to the knock sensor
- Engine overheating causing sensor malfunction
