P0507 Code: Idle Control System RPM Higher Than Expected
P0507 means idle speed is higher than the computer expects. Learn the common symptoms, causes, severity, and typical repair costs.
The P0507 code means idle speed is higher than the computer expects. It is stored when the engine computer sees a signal or operating condition outside the expected range.
Vehicle speed, idle, and voltage codes affect drivability systems that depend on stable speed data, idle control, and electrical power. The right fix depends on live data, freeze-frame information, service history, and whether other codes are present.
Symptoms
- High idle RPM
- Vehicle creeps harder at stops
- Check engine light
- Surging idle
- Poor fuel economy
- Harsh engagement into gear
Common Causes
- Vacuum leak
- Dirty throttle body
- Throttle plate sticking
- Idle air control valve issue
- PCV system leak
- ECM idle relearn needed
Severity
Low to moderate. High idle may not stop the vehicle, but it can make low-speed control harder and waste fuel.
Typical Repair Costs
$75 to $600
- The lower end usually covers inspection, cleaning, wiring repair, or a simple sensor replacement.
- The higher end applies when parts are hard to access or when the code is caused by a larger mechanical, emissions, or transmission problem.
- Always diagnose before replacing parts, because one code can be triggered by several related systems.
Frequently Asked Questions
What does code P0507 mean?
P0507 means idle speed is higher than the computer expects. The exact cause should be confirmed with diagnostic data before replacing parts.
Can I drive with a P0507 code?
It depends on symptoms. If the car runs poorly, overheats, stalls, shifts harshly, or the check engine light flashes, limit driving and diagnose it promptly.
What is the most common fix for P0507?
Common fixes include addressing vacuum leak, dirty throttle body, throttle plate sticking, but testing is needed to avoid replacing the wrong part.
