DTC P0507: Idle Control System RPM Higher Than Expected

  1. Turn the ignition switch ON (II).
  2. Clear the DTC with the HDS.
  3. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on, then let it idle.
  4. Monitor the OBD STATUS for DTC P0507 in the DTCs MENU with the HDS.

    Does the screen indicate FAILED? 

    1. YES -  Go to step 5.
    2. NO -  If the screen indicates PASSED, intermittent failure, system is OK at this time. If the screen indicates EXECUTING, let the engine idle until a result comes on. If the screen indicates OUT OF CONDITION, recheck with different load conditions (electrical, A/C, gear position, etc.), then go to step  3.
  5. Check for vacuum leaks at these parts:
    • PCV valve
    • PCV hose
    • EVAP canister purge valve
    • Intake manifold
    • Throttle body
    • Brake booster and hose

    Are there any leaks?

  10. Check for Temporary DTCs or DTCs with the HDS.

    Are any Temporary DTCs or DTCs indicated? 

    1. YES -  If DTC P0507 is indicated, check for poor connections or loose terminals at the throttle body, the throttle actuator control module, and the ECM/PCM, then go to step  1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
    2. NO -  Go to step 11.

If the screen indicates EXECUTING, let the engine idle until a result comes on. If the screen indicates OUT OF CONDITION, recheck with different load conditions (electrical, A/C, gear position, etc.), then go to step  9.
