What causes code p0325 on Nissan Quest?

Answer 1

Code P0325 in a Nissan Quest indicates a problem with the knock sensor circuit, specifically related to the knock sensor's performance or voltage. This can be caused by a faulty knock sensor, damaged wiring or connectors in the circuit, or issues with the engine control unit (ECU). The knock sensor is responsible for detecting engine knock or pre-ignition, and if it fails, it can affect engine performance and efficiency. Diagnosing the issue often requires checking the sensor, wiring, and connectors for faults.
