DTC P2112:00

Throttle valve actuator motor current range/performance problem

DETECTION CONDITION
•  The throttle valve actuator control duty ratio is 95 % or more with the ignition switched ON (engine on).
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)

Diagnostic Procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  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 INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT THROTTLE BODY CONNECTOR CONDITION
•  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
INSPECT PCM CONNECTOR CONDITION
•  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
INSPECT THROTTLE VALVE ACTUATOR CIRCUIT FOR OPEN CIRCUIT
•  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 THROTTLE VALVE
•  Perform the Electronic Control Throttle Operation Inspection.
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to Step 8.
No
Go to the next step.
7
INSPECT THROTTLE VALVE ACTUATOR
•  Inspect the throttle valve actuator.
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
No
Go to the next step.
8
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
