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 is 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
