Code P2103 Toyota Description
The opening angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle with motor body assembly. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to driver inputs.
The ECM monitors the electrical current through the electronic actuator and detects malfunctions and open circuits in the throttle actuator based on this value. If the current is outside the standard range, the ECM determines that there is a malfunction in the throttle actuator. In addition, if the throttle valve does not function properly (for example, stuck on), the ECM determines that there is a malfunction. The ECM then illuminates the MIL and stores a Diagnostic Trouble Code (DTC).

- Dirty throttle body
- Faulty Throttle Actuator
- Throttle Actuator harness is open
- Throttle Actuator circuit poor electrical connection
- Faulty Throttle with Motor Body Assembly
- Faulty Engine Control Module (ECM)

I had this code in my 2004 Camry 2.4L. The car just quit going down the road at ~45mph. I was able to restart the car and limp home at ~1800RPM. Eventually, the car would not go above idel RPM regardless of throttle position. Pulled the throttle body - butterfly valve was ceased closed. Ordered a new one (buyautoparts.com; Throttle Body 47-60110 AN, $222.75). In the mean time, I drilled out the aluminum rivets in the throttle body, which exposed three gears. Re moved three more screws, revealing a small electrical motor. LOTS of corrosion. Cleaned and lubed with WD40. Rotated the electric motor with my drill, then tested with 12v battery. Worked fine, so reassembled all, using machine screws in place of the rivets. Reinstalled assembly, and started her up. Initially ran pretty rough, but quickly smoothed out. Now running as smooth as baby's butt. Hopefully will last until new assembly arrives. Total time for remove/replace about 30 minutes.
