   DTC Description	OBD STATUS
   P0507 Idle Control System RPM Higher Than Expected

   Does the HDS indicate FAILED?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   If the HDS indicates PASSED, intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot - Refer to: How to Troubleshoot the Fuel and Emissions Systems . If the HDS indicates EXECUTING, keep idling until a result comes on. If the HDS indicates OUT OF CONDITION, recheck with different load conditions (electrical, A/C, gear position, etc.), then go to step 1-4.

2. Vacuum leak check

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Check for vacuum leaks at these parts:

   • PCV valve
   • PCV hose
   • EVAP canister purge valve
   • Throttle body
   • Intake manifold

   Are there any leaks?

   YES 

   Repair or replace the leaking part(s).

   NO 

   Recheck with different load conditions (turn on the headlights, the blower motor, or the A/C, change the gear position, etc.).
