DTC P2101:00 [MZR-CD (RF Turbo)]

id0102f1707700

DTC P2101:00

Intake shutter valve position sensor circuit high input
DETECTION CONDITION
•  PCM monitors the intake shutter valve position sensor circuit current. If the PCM detects that the intake shutter valve position sensor circuit current is excessively high, the PCM determines that the electronic intake shutter valve actuator circuit has a malfunction.
Diagnostic support note
•  The MIL 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 the first drive cycle.
•  FREEZE FRAME DATA is available.
•  DTCs are stored in the PCM memory.
POSSIBLE CAUSE
•  Short to the power supply between intake shutter valve terminal F and PCM terminal 86
•  Intake shutter valve actuator malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to available Service Information.
•  If vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT CONTROL CIRCUIT OF INTAKE SHUTTER VALVE ACTUATOR FOR SHORT TO POWER SUPPLY
•  Switch the ignition to off.
•  Disconnect the intake shutter valve and PCM connectors.
•  Switch the ignition to ON (Engine off).
•  Measure the voltage between intake shutter valve terminal F (harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a short to power supply, then go to Step 5.
No
Go to the next step.
4
INSPECT INTAKE SHUTTER VALVE ACTUATOR
•  Inspect the intake shutter valve actuator.
•  Is it normal?
Yes
Go to the next step.
No
Replace the intake shutter valve, then go to the next step.

5
VERIFY TROUBLESHOOTING OF DTC P2101:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Switch the ignition to ON (Engine off).
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and warm it up completely.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No
Go to the next step.
6
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 (RF Turbo)].)
No
Troubleshooting completed.
