Circuit Description
WARNING: This page is about a different car, the 2003 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
The throttle motor is operated by the ECM and it opens and closes the throttle valve. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to make the throttle valve opening angle properly in response to the driving condition.
If this DTC is stored, the throttle valve is locked at a certain opening angle. Also, the whole electronically controlled throttle operation is cancelled until the system returns to normal and the ignition switch is turned OFF. The electrical throttle system does not use throttle cable.
Detecting conditions of DTCs are:
- If the following conditions continue for 2 seconds:
- Throttle control motor output duty is greater than or equal to 80%.
- Throttle control motor current is less than 0.5 A.
- Throttle control motor current is greater than or equal to 10 A.
- If throttle control motor current is greater than or equal to 7 A and continues for 0.6 second.
