Code P0052 Mitsubishi Description
The P0052 diagnostic trouble code (DTC) for Mitsubishi vehicles specifically indicates an issue with the Cylinder 2-3 Heated Oxygen Sensor (HO2S) Front Heater Control Circuit being detected as high. The HO2S, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases to ensure optimal fuel efficiency and emissions control. The front heater control circuit is responsible for heating the sensor to reach operating temperature quickly, allowing it to function effectively.
Common Causes of P0052 Mitsubishi
- Faulty oxygen sensor
- Damaged wiring or connectors in the heater circuit
- Blown fuse related to the sensor's heater
- ECM malfunction
- Environmental factors such as exposure to excessive heat or moisture
Symptoms of P0052 Mitsubishi
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Illuminated check engine light
- Failed emissions test
How to Fix P0052 Mitsubishi
- Begin by conducting a thorough inspection of the oxygen sensor and its wiring for any visible damage or corrosion.
- Test the sensor's heater circuit using a multimeter to check for proper voltage levels.
- Replace the oxygen sensor if it is found to be faulty, ensuring to use a high-quality replacement part compatible with the vehicle's make and model.
- Repair or replace any damaged wiring or connectors in the heater circuit.
- Clear the DTC using an OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0052 Mitsubishi
The typical repair costs for addressing a P0052 code in a Mitsubishi vehicle can range from $150 to $400, including parts and labor.

Frequently Asked Questions about P0052 Mitsubishi Code
1. What does the OBDII code P0052 mean on a Mitsubishi?
P0052 indicates a problem with the heater control circuit of the front heated oxygen sensor (HO2S) for cylinder bank 2-3. The sensor's heater circuit voltage is higher than expected.
2. What are the common symptoms of code P0052 on a Mitsubishi?
Symptoms include poor fuel efficiency, rough idling, increased emissions, the check engine light turning on, and potentially a failed emissions test.
3. What causes the P0052 code to appear in a Mitsubishi vehicle?
Common causes include a faulty oxygen sensor, damaged wiring or connectors, a short circuit, or a malfunctioning engine control module (ECM).
4. Can I drive my Mitsubishi with a P0052 code?
While the vehicle may still be drivable, it’s not recommended because the issue can lead to poor engine performance, higher emissions, and possible long-term damage.
5. How do I diagnose the P0052 code on my Mitsubishi?
Start by checking the oxygen sensor wiring and connectors for damage, test the heater circuit for continuity, and use a multimeter to verify proper voltage and resistance.
6. How do I fix the P0052 code on a Mitsubishi?
Repairs may include replacing the faulty oxygen sensor, repairing or replacing damaged wiring, or addressing issues with the ECM if needed.
7. How much does it cost to repair the P0052 code on a Mitsubishi?
The repair cost varies, but replacing an oxygen sensor typically ranges from $150 to $500, depending on parts and labor costs.
8. Can a dirty or clogged oxygen sensor trigger the P0052 code?
No, this code is specifically related to the heater control circuit, not sensor contamination. However, a faulty sensor can still cause the code.
9. Does the P0052 code affect fuel economy?
Yes, a malfunctioning oxygen sensor heater can cause improper air-fuel mixture readings, leading to decreased fuel efficiency.
10. Should I clear the P0052 code after making repairs?
Yes, clear the code with an OBDII scanner after completing repairs, then test drive the vehicle to ensure the issue is resolved.
