DTC P2100:00 [L5]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSES

DTC P2100:00	Throttle valve actuator circuit open
DETECTION CONDITION	The PCM monitors the electronic throttle valve actuator current. If the PCM detects 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) The MIL illuminates 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	Throttle body connector or terminal malfunction Throttle valve actuator malfunction PCM connector or terminal malfunction Open circuit in wiring harness between throttle body terminal F and PCM terminal 2BE Open circuit in wiring harness between throttle body terminal E and PCM terminal 2BF PCM malfunction
