DTC P2112:00

Throttle valve actuator motor current range/performance problem

DETECTION CONDITION

• If the duty ratio is 95 % or more, the PCM determines that there is a throttle valve actuator control system range/performance problem.

Diagnostic support note

• This is a continuous monitor (CCM).

• The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

• DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

• Restricts the upper limit of the engine speed.

• Stops the drive-by-wire control (throttle valve is open at approx. 8 ° by return spring force).

POSSIBLE CAUSE

• Throttle body connector or terminals malfunction

• PCM connector or terminals malfunction

• Open circuit in wiring harness between the following terminals:

• Throttle body terminal E—PCM terminal 1CG

• Throttle body terminal F—PCM terminal 1CC

• Throttle valve malfunction

• Throttle valve actuator malfunction

• PCM malfunction

• Throttle valve actuator control module malfunction (built-into PCM)

STEP

INSPECTION

ACTION

1

• Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?

Yes

Go to the next step.

No

Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.

2

• Verify related Service Bulletins and/or on-line repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

• If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

• Switch the ignition off.

• Disconnect the throttle body connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 8.

No

Go to the next step.

4

• Disconnect the PCM connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 8.

No

Go to the next step.

5

• Verify that the throttle body and PCM connectors are disconnected.

• Inspect for continuity between the following terminals (wiring harness-side):

• Throttle body terminal E—PCM terminal 1CG

• Throttle body terminal F—PCM terminal 1CC

• Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• Throttle body terminal E—PCM terminal 1CG

• Throttle body terminal F—PCM terminal 1CC

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has an open circuit.

Go to Step 8.

6

• Inspect the throttle valve.

  (See THROTTLE BODY INSPECTION [SKYACTIV-G 2.5].)

• Is there any malfunction?

Yes

Replace the throttle body, then go to Step 8.

(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

No

Go to the next step.

7

• Inspect the throttle valve actuator.

  (See THROTTLE BODY INSPECTION [SKYACTIV-G 2.5].)

• Is there any malfunction?

Yes

Replace the throttle body, then go to the next step.

(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

No

Go to the next step.

8

• Always reconnect all disconnected connectors.

• Clear the DTC from the PCM memory using the M-MDS.

  (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.5].)

• Perform the KOER self test.

  (See KOEO/KOER SELF TEST [SKYACTIV-G 2.5].)

• Is the same DTC present?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the PCM.

  (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

Go to the next step.

No

Go to the next step.

9

• Perform the “AFTER REPAIR PROCEDURE”.

  (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.5].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SKYACTIV-G 2.5].)

No

DTC troubleshooting completed.
