DTC P2100:00 [L3 Turbo]

DTC P2100:00	Throttle valve actuator circuit open
DETECTION CONDITION	• The PCM monitors the electronic throttle valve actuator current. If the PCM detects that the electronic throttle valve actuator current is below the threshold current, the PCM determines that the electronic throttle valve actuator circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA (Mode 2)/Snapshot data is available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE	• Throttle body connector or terminals malfunction • Throttle valve electrical malfunction • Short to ground in wiring harness between the following terminals: ― Throttle body terminal F—PCM terminal 2A ― Throttle body terminal E—PCM terminal 2B • PCM connector or terminals malfunction • Open circuit in wiring harness between the following terminals: ― Throttle body terminal F—PCM terminal 2A ― Throttle body terminal E—PCM terminal 2B • PCM malfunction
