Your 2021 Rogue sits at a stoplight and the engine seems to hunt, surge, or vibrate more than normal. The P0507 code indicates the idle speed is higher than expected, and the engine computer is struggling to control it. This points to air bypassing the throttle or a confused idle control system.
Understanding P0507
The P0507 code means "Idle Control System RPM Higher Than Expected." Modern Rogues use electronic throttle control—there's no separate idle air control valve. The code triggers when the engine is idling faster than the computer commands, often with accompanying roughness as the system tries to compensate.
Symptoms You're Experiencing
- Idle RPM fluctuating or hunting
- Engine feels rough or vibrates at stops
- RPM may hang high when coming to a stop
- Possible surging while in Park
- May stall occasionally after the surge
- Check engine light with P0507
What Causes High Idle
- Vacuum leak: Unmetered air entering after the throttle body
- Dirty throttle body: Carbon buildup preventing proper throttle closure
- Intake manifold leak: Air entering around the gasket or plenum
- Faulty throttle body: Electronic throttle not positioning correctly
- Air filter or intake issue: Restricted or damaged intake system
- EVAP system leak: Purge valve stuck open
Diagnostic Steps
- Check for vacuum leaks around the intake manifold
- Inspect the throttle body for carbon deposits
- Verify the throttle plate closes completely
- Check for a stuck-open purge valve
- Monitor idle air volume learning values with scan tool
Throttle Body Cleaning
On many Rogues, throttle body cleaning resolves P0507. Carbon builds up on the throttle plate and bore, preventing complete closure. This is a common maintenance item on direct injection engines.
Repair Costs
- Throttle body cleaning: $100-$200 (or DIY for $10)
- Vacuum leak repair: $100-$300
- Intake manifold gasket: $300-$600
- Throttle body replacement: $400-$800
- Purge valve replacement: $100-$250
