id0102s4214500

DTC P2118:00

Intake shutter valve control duty signal error
DETECTION CONDITION
•  The intake shutter valve control duty value is 90 % for a continuous 2 s.
MONITORING CONDITIONS
―  The following DTCs are not detected:
•  Intake shutter valve position sensor: P0122:00, P0123:00
•  Intake shutter valve: P1589:00, P2101:00
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during 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
•  Intake shutter valve position sensor 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 9.
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 9.
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 9.
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 Step 9.
(See INTAKE SHUTTER VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
8
INSPECT INTAKE SHUTTER VALVE POSITION SENSOR
•  Reconnect all disconnected connectors.
•  Inspect the intake shutter valve position sensor.
•  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.
9
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this 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.
10
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.
