P2102
Throttle Actuator "A" Control Motor Circuit Low
DTC P2102, sometimes indicated as P210200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing throttle actuator "a" control motor circuit low.
This code is set when the PCM detects that the throttle actuator "A" control motor circuit is low.
Possible causes of this code include a defective throttle actuator, a wiring issue, or a problem with the PCM.
If this code is stored, the most likely cause is a defective throttle actuator. If the throttle actuator is not defective, the next most likely cause is a wiring issue. If the PCM is defective, the code will not be cleared.
If this code is stored, the best way to troubleshoot it is to start by checking the wiring and connector at the throttle actuator. If the wiring and connector are OK, then the next step is to test the throttle actuator.

2004 TOYOTA CAMRY with 86365.0 miles
I started my 2004 Toyota Camry le in my driveway. At the time of ignition, the engine chugged then idled as usual, but the check engine light illuminated. I put the vehicle into reserve and rolled back about 20 feet into the street, then put the vehicle into drive. I stepped onto the accelerator pedal and nothing happened. The vehicle continued to idle while in the drive gear, however, it would not accelerate despite me pressing the pedal all the way to the floor. I turned off the vehicle and waited approximately 10 minutes, then restarted the vehicle. The check engine light was no longer illuminated and when the vehicle was put into drive the accelerator worked properly. I took the vehicle to a local repair facility and was told about 2 codes in my computer: P2112 - throttle actuator control system - stuck closed, and P2102 - throttle actuator control motor circuit low (suggesting the throttle body be replaced). I contacted the local dealership in farmington, mi at which they reported throttle body issues were a known and common problem that they get calls about frequently, but there was no recall on the vehicle regarding this issue at this time. I was fortunate that i was on a side street near my home when this occurred, but am concerned that this could happen again while driving (as i have read in many safety complaints on the vehicle safety website).
