SFI SYSTEM, Diagnostic DTC:P2101 and P2107

DTC Code DTC Name
P2101 Throttle Actuator "A" Control Motor Circuit Range / Performance
P2107 Throttle Actuator "A" Control Module Processor

DESCRIPTION

The throttle actuator is operated by the ECM and opens and closes the throttle valve using gears.

The opening angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle body with motor assembly. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to driver inputs.

DTC No.

  2. CHECK HARNESS AND CONNECTOR (THROTTLE BODY WITH MOTOR ASSEMBLY - ECM)

    1. Disconnect the throttle body with motor assembly connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

  3. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (VISUALLY CHECK THROTTLE VALVE)

    1. Check for contamination between the throttle valve and housing. If necessary, clean the throttle body with motor assembly. Also check that the throttle valve moves smoothly.

      OK

      Throttle valve is not contaminated with foreign matter and moves smoothly.

      Tip:

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

  5. CHECK WHETHER DTC OUTPUT RECURS (DTC P2101 OR P2107)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Clear the DTCs.

      Powertrain > Engine > Clear DTCs

    5. Turn the ignition switch off and wait for a few minutes.

    6. Perform the drive test.

    7. Turn the GTS on.

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

    9. Check for DTCs.
