Mitsubishi P0507 Error Code: How to Fix It

Q: What causes P0507 code in Mitsubishi vehicles?

The most common causes are vacuum leaks, dirty throttle body, faulty idle air control valve, contaminated mass airflow sensor, or issues with the throttle position sensor. Carbon buildup and worn engine mounts can also contribute to this code.

Q: Can I drive with P0507 code?

You can drive short distances with P0507, but it's not recommended for extended periods. High idle can cause excessive fuel consumption, engine overheating, and premature wear of engine components. Address the issue promptly to avoid further problems.

Q: How much does it cost to fix P0507?

DIY repairs typically cost $20-50 for cleaning supplies and basic parts. Professional repair costs range from $150-400 depending on the root cause, with vacuum leak repairs being less expensive than throttle body or IAC valve replacement.

Q: Will P0507 cause my Mitsubishi to fail emissions?

Yes, P0507 can cause your vehicle to fail emissions testing because the engine is not operating within normal parameters. The high idle affects the air/fuel mixture and can impact catalyst efficiency.

Abstract

The P0507 error code in Mitsubishi vehicles indicates that the engine's idle RPM is running higher than the expected range programmed into the Engine Control Module (ECM). This typically means your engine is idling above 800-1000 RPM when it should be idling around 600-750 RPM when warm.
