Code P0325 1999 Toyota Camry Description

The P0325 code for a 1999 Toyota Camry indicates a Knock Sensor Circuit Malfunction. The knock sensor is a crucial component of the engine management system, responsible for detecting abnormal combustion in the engine. When the knock sensor detects unusual vibrations or noises that could indicate pre-ignition or detonation, it sends a signal to the engine control module (ECM) to adjust the ignition timing accordingly. A malfunctioning knock sensor can lead to poor engine performance, reduced fuel efficiency, and potential damage to the engine over time.
