DTC P2101:00 [SKYACTIV-D 2.2]

id0102s4707700

DTC P2101:00

Intake shutter valve control circuit overcurrent
DETECTION CONDITION
•  When any of the following conditions is met:
―  The intake shutter valve drive current exceeds the specification for a continuous 2 s.
―  A condition has continued for 2 s in which the temperature of the DC motor drive circuit is 175 °C {347 °F} or more.
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
•  Inhibits the EGR control.
•  Inhibits the diesel particulate filter regeneration control.
•  Inhibits engine-stop by operating the i-stop function.
•  PCM restricts engine-transaxle integration control.
POSSIBLE CAUSE
•  Intake shutter valve/intake shutter valve position sensor connector or terminals malfunction
•  Short to ground in wiring harness between intake shutter valve/intake shutter valve position sensor terminal B and PCM terminal 1AX
•  PCM connector or terminals malfunction
•  Intake shutter valve malfunction
•  PCM malfunction

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
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition off, then ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Are any other PENDING CODEs and/or DTCs present?
Yes
Go to the applicable PENDING CODE or DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
Go to the next step.
4
INSPECT INTAKE SHUTTER VALVE/INTAKE SHUTTER VALVE POSITION SENSOR CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the intake shutter valve/intake shutter valve position sensor 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 INTAKE SHUTTER VALVE CONTROL CIRCUIT FOR SHORT TO GROUND
•  Verify that the intake shutter valve/intake shutter valve position sensor connector is disconnected.
•  Inspect for continuity between intake shutter valve/intake shutter valve position sensor terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
If the short to ground circuit could be detected in the wiring harness:
•  Refer to the wiring diagram and verify whether or not there is a common connector between intake shutter valve/intake shutter valve position sensor terminal B and PCM terminal 1AX.
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 a short to ground.
―  Repair or replace the malfunctioning part.
If there is no common connector:
―  Repair or replace the wiring harness which has a short to ground.
If the short to ground circuit could not be detected in the wiring harness:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 8.
No
Go to the next step.
6
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.
7
INSPECT INTAKE SHUTTER VALVE
•  Inspect the intake shutter valve.
•  Is there any malfunction?
Yes
Replace the intake shutter valve, then go to the next step.
(See INTAKE SHUTTER VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
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.
•  Perform the DTC Reading Procedure.
•  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.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
