DTC P2101 [MZR-CD (RF Turbo)]

id0102f1811100

DTC P2101 | 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 • 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 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 REPAIR INFORMATION AVAILABILITY • Check for related Service Bulletins and/or on-line repair information availability. • Is any related repair information available? | Yes | Perform the repair or diagnosis according to the available repair information. • If the 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 • Turn the engine switch to off. • Disconnect the intake shutter valve and PCM connectors. • Turn engine switch to the ON position (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. (See INTAKE SHUTTER VALVE INSPECTION [MZR-CD (RF Turbo)].) • Is it normal? | Yes | Go to the next step.
No | Replace the intake shutter valve, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
5 | VERIFY TROUBLESHOOTING OF DTC P2101 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn engine switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the WDS or equivalent. • 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". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
