Code P0012 Mitsubishi Description
The P0012 code in Mitsubishi vehicles indicates a problem with the camshaft position timing being over-retarded. This means that the engine control module (ECM) has detected that the camshaft timing is not within the specified parameters. The camshaft is responsible for controlling the opening and closing of the engine's intake and exhaust valves, which is crucial for the engine's performance and efficiency. When the camshaft timing is over-retarded, it can lead to poor engine performance, reduced fuel efficiency, and potentially cause damage to the engine over time.
Common Causes of P0012 Mitsubishi
- Faulty camshaft position sensor
- Worn or stretched timing chain or belt
- Malfunctioning VVT solenoid or actuator
- Problem with the oil control valve
Symptoms of P0012 Mitsubishi
- Rough idling or stalling
- Decreased engine performance
- Engine misfires
- Reduced fuel efficiency
- Check Engine Light illuminated on the dashboard
How to Fix P0012 Mitsubishi
- Diagnose the issue using a scan tool to confirm the P0012 code and identify the specific cause of the problem.
- Inspect the camshaft position sensor and replace it if faulty.
- Check the timing chain or belt for wear and tension, replacing it if necessary.
- Test the VVT system components, such as the solenoid and actuator, and replace any faulty parts.
- Verify the oil control valve's operation and replace it if it is the source of the issue.
Cost to Fix P0012 Mitsubishi
The cost of repairing a P0012 code in a Mitsubishi vehicle can vary depending on the specific cause of the issue and the labor rates in your area.

Frequently Asked Questions about P0012 Mitsubishi Code
1. What does the OBDII code P0012 mean on a Mitsubishi?
P0012 indicates "Camshaft Position Timing Over-Retarded" for Bank 1, meaning the intake camshaft timing is delayed beyond the expected range.
2. What are the common symptoms of the P0012 code on a Mitsubishi?
Symptoms may include rough idling, poor acceleration, reduced fuel efficiency, engine misfiring, or the engine failing to start.
3. What causes the P0012 code to appear in a Mitsubishi?
Common causes include a faulty variable valve timing (VVT) solenoid, dirty or low engine oil, timing chain issues, or a malfunctioning camshaft position sensor.
4. Can dirty engine oil trigger the P0012 code in a Mitsubishi?
Yes, dirty or low engine oil can clog the VVT system, impacting camshaft timing and triggering the P0012 code.
5. Is it safe to drive a Mitsubishi with the P0012 code?
Driving with the P0012 code is not recommended, as it can lead to poor performance, increased emissions, and potential engine damage if the issue is not resolved.
6. How do I fix the P0012 code on my Mitsubishi?
Start by checking and replacing dirty or low engine oil. If the issue persists, inspect the VVT solenoid, camshaft position sensor, and timing chain for faults.
7. What tools do I need to diagnose the P0012 code on a Mitsubishi?
You’ll need an OBDII scanner to read the code and possibly a multimeter and oil pressure gauge to test related components.
8. Can a bad VVT solenoid cause the P0012 code on a Mitsubishi?
Yes, a malfunctioning VVT solenoid can prevent proper oil flow to the timing system, causing over-retarded camshaft timing.
9. How much does it cost to repair the P0012 code on a Mitsubishi?
Repair costs vary depending on the root cause, ranging from $50 for an oil change to $1,000+ for timing chain replacement.
10. Can resetting the code fix the P0012 issue on a Mitsubishi?
Resetting the code without addressing the underlying problem is temporary, as the code will likely reappear until the issue is resolved.
