Code P0325 Mitsubishi Description
The P0325 diagnostic trouble code (DTC) for Mitsubishi vehicles indicates a knock sensor circuit malfunction. The knock sensor is a crucial component in the engine control system that detects abnormal combustion, often referred to as engine knocking or pinging. 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 and optimize performance.
Common Causes of P0325 Mitsubishi
- Faulty knock sensor
- Wiring harness issues or electrical connections
- Engine mechanical problems causing abnormal combustion
- ECM software or hardware issues
- Environmental factors like extreme temperatures or poor fuel quality
Symptoms of P0325 Mitsubishi
- Engine knocking or pinging noises
- Decreased engine performance or acceleration
- Poor fuel economy
- Check Engine Light illuminated
- Engine misfires or rough idle
How to Fix P0325 Mitsubishi
- Diagnose the issue by using a scan tool to read the DTC and perform a visual inspection of the knock sensor and wiring.
- Test the knock sensor using a multimeter to check for proper resistance and continuity.
- Replace the knock sensor if it is faulty, ensuring proper installation and connection to the ECM.
- Inspect and repair any damaged wiring harness or electrical connections.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0325 Mitsubishi
The cost of repairing a knock sensor circuit malfunction (P0325) in a Mitsubishi vehicle can vary depending on several factors, including the make and model of the vehicle, the location of the repair shop, and the specific parts and labor required for the repair. In general, the cost of replacing a knock sensor and addressing related issues can range from $150 to $400, including parts and labor.

- Common symptoms include engine knocking or pinging noises, loss of engine power, poor fuel economy, and illuminated check engine light.
2. What are the possible causes of a P0325 trouble code in a Mitsubishi?
- The code P0325 in a Mitsubishi is often caused by a faulty knock sensor, wiring issues in the knock sensor circuit, or a malfunctioning Engine Control Module (ECM).
3. How does a knock sensor work in a Mitsubishi vehicle?
- A knock sensor in a Mitsubishi detects abnormal combustion noises (knocking or pinging) in the engine. It sends signals to the ECM to adjust ignition timing and prevent engine damage.
4. Can a P0325 code be triggered by a loose or disconnected knock sensor connector?
- Yes, a loose or disconnected knock sensor connector can trigger a P0325 code in a Mitsubishi, as it disrupts the communication between the sensor and the ECM.
5. How can I diagnose a P0325 code in my Mitsubishi?
- Diagnosing a P0325 code involves checking the knock sensor and its wiring for any damage, testing the sensor's resistance, and inspecting the ECM for any faults.
6. What are the repair options for a P0325 code in a Mitsubishi?
- Repair options for a P0325 code include replacing the knock sensor, repairing or replacing damaged wiring, and reprogramming or replacing the ECM if necessary.
7. Is it safe to continue driving with a P0325 code in a Mitsubishi?
- It is not recommended to continue driving with a P0325 code, as it can lead to engine damage and reduced performance. It is best to address the issue promptly.
8. Can a P0325 code in a Mitsubishi be triggered by using low-quality fuel?
- Using low-quality fuel can potentially lead to engine knocking, which may trigger a P0325 code in a Mitsubishi by causing the knock sensor to detect abnormal combustion.
9. How much does it typically cost to repair a P0325 code in a Mitsubishi?
- The cost to repair a P0325 code in a Mitsubishi can vary depending on the exact cause of the issue. It may range from $150 to $500 for parts and labor.
10. Can a P0325 code be intermittent in a Mitsubishi?
- Yes, a P0325 code can be intermittent in a Mitsubishi, meaning it may come and go. It is essential to address the underlying issue to prevent potential engine damage.
