P0507 Idle Control System RPM - Higher Than Expected

DESCRIPTION

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P0507 Idle Control System RPM - Higher Than Expected

DTC Detection Condition


    Enable Criteria (1)

  • Battery voltage between 10 V and 16 V

  • Idle closed loop control active


    Enable Criteria (2)

  • Vehicle speed 0 km/h

  • Accelerator pedal position less than 0.195%


    Malfunction Criteria (1)

  • Engine speed - target engine speed 200 rpm or more


    Malfunction Criteria (2)

  • Engine speed - target engine speed 496 rpm or more


    Diagnostic Mask

  • The MIL will be illuminated if a fault is present for 2 consecutive trips


    Monitor

  • Continuous


    Potential failure modes

  • Induction system air leak

  • Excessive engine load from front end accessory drive system, water pump, power steering, alternator

  • Electronic Throttle Control

  • Electronic throttle control system

  • Intake system

  • PCV hose connections

  • ECM

 Comes on DTC stored

MONITOR DESCRIPTION

The ECM controls the engine idle speed using a combination of spark advance and throttle blade adjustment. If this control cannot attain the desired idle speed a fault is diagnosed.

CAUTION / NOTICE / HINT

Tech Tips


  • The following conditions may also cause DTC P0506 to be stored:


    1. The floor carpet overlapping slightly onto the accelerator pedal, causing the accelerator pedal to be slightly depressed and therefore the throttle valve position to be slightly open.

    2. The accelerator pedal being not fully released.

  • Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

  • Refer to "Data List / Active Test" [Engine Speed, ISC Feedback Value and ISC Learning Value].

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0507)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Read the DTCs.

      Result Proceed to
      DTC P507 is output A
      DTC P507 and other DTCs are output B

      Tech Tips

      If any DTCs other than P507 are output, troubleshoot those DTCs first.

  2. READ FREEZE FRAME DATA


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Using the GTS, check "ISC Learning Value" in the freeze frame data.

  3. REMOVE FOREIGN MATTER (CLEAN THROTTLE BODY WITH MOTOR ASSEMBLY)


    1. Clean off any deposits from the inside of the throttle body assembly.

      *e Deposits - -

      1. Push open the throttle valve and wipe off any carbon from the valve and bore using a piece of cloth soaked in non-residue solvent.

      Note


      • Make sure that the cloth or your fingers do not get caught in the valve.

      • Make sure that foreign matter does not enter the throttle valve.

      • Do not directly apply non-residue solvent to the throttle body with motor assembly or wash the throttle body with motor assembly. Cleaning solvent may leak into the motor from the shaft and cause problems such as rust or valve movement problems.

      • If there is coating material on the edge of the valve, be careful not to remove it.

      • Push the throttle valve open gently with your finger and check that the throttle valve moves smoothly.

      Tech Tips


      • If the throttle valve does not move smoothly, replace the throttle body with motor assembly.

      • Perform "Inspection After Repair" after cleaning the throttle body with motor assembly.

  4. CHECK WHETHER DTC OUTPUT RECURS


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTCs.

    5. Turn the engine switch off and wait for at least 30 seconds.

    6. Turn the engine switch on (IG).

    7. Turn the GTS on.

    8. Start the engine.

    9. Warm up the engine.

    10. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

    11. Input the DTC: P0507.

    12. Check the DTC judgment result.

      Tech Tips

      Perform "Inspection After Repair" after replacing the throttle body with motor assembly.
