Details of the Toyota p0325 OBD Code
Fault code P0325 in a Toyota indicates a problem with the knock sensor circuit.
Code P0325 for Toyota vehicles means that there is a Knock Sensor Circuit Malfunction (Bank 1).
This code is triggered by the Engine Control Module (ECM) when it detects a problem with the knock sensor circuit on bank 1 of the engine.
The knock sensor is responsible for detecting abnormal vibrations or knocking in the engine, which can indicate preignition and potential engine damage.
When the ECM receives a signal indicating a malfunction in the knock sensor circuit, it triggers the P0325 fault code.
Mechanic’s Tech Notes
For Toyota code P0325, diagnose faulty knock sensor causing engine performance issues.
To diagnose and fix OBDII code P0325 on a Toyota, start by checking the knock sensor circuit for any faults.
Use a voltmeter to test the sensor’s resistance and ensure it falls within specifications.
Inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Verify the knock sensor signal using a scan tool to see if it matches engine conditions.
If the sensor and wiring check out, the issue may lie with the engine control module (ECM).
Consider reprogramming or replacing the ECM if necessary.
