Code P0325 2000 Toyota Echo Description
The P0325 code for a 2000 Toyota Echo indicates a Knock Sensor Circuit Malfunction. The knock sensor is a crucial component in the engine management system that detects abnormal vibrations or knocking in the engine. When the knock sensor detects these vibrations, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage. A malfunctioning knock sensor can lead to poor engine performance, reduced fuel efficiency, and potential long-term damage if left unaddressed.
