DTC P2101:00 [MZR-CD 2.2]

id0102f3707700

DTC P2101:00

Intake shutter valve control circuit range/performance malfunction
DETECTION CONDITION
•  The PCM monitors intake shutter valve control current when the ignition switch is ON position. If the intake shutter valve control current is above threshold, the PCM determines that the intake shutter valve control circuit has a malfunction.
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (mode2) and snapshot data are available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Intake shutter valve connector or terminal malfunction
•  Short to ground between intake shutter valve terminal B and PCM terminal 2BB
•  Intake shutter valve malfunction
•  PCM connector or terminal malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE2)
•  Is DTC P2101:00 on FREEZE FRAME DATA (mode2)?
Yes
Go to the next step.
No
Go to troubleshooting procedures for DTC in FREEZE FRAME DATA (mode2).
(See DTC TABLE [MZR-CD 2.2].)
2
VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED
•  Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (mode2) and snapshot data on repair order, then go to the next step.
3
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.
4
INSPECT INTAKE SHUTTER VALVE CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the intake shutter valve connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace terminal, then go to Step 8.
No
Go to the next step.
5
INSPECT INTAKE SHUTTER VALVE CONTROL CIRCUIT FOR SHORT TO GROUND
•  Disconnect intake shutter valve and PCM connectors.
•  Inspect for continuity between intake shutter valve terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
If the short to ground circuit could be detected:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 8.
No
Go to the next step.
6
INSPECT INTAKE SHUTTER VALVE
•  Inspect the intake shutter valve.
•  Is the intake shutter valve normal?
Yes
Go to the next step.
No
Replace the intake shutter valve, then go to Step 8.
(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD 2.2].)
7
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace terminal, then go to the next step.
No
Go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P2101:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Perform the KOER self test.
•  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 [MZR-CD 2.2].)
No
DTC troubleshooting completed.
