Toyota 1kz Throttle Position

The throttle position sensor is mounted in the throttle body and detects the throttle valve opening angle. When the throttle valve is fully closed, the IDL contacts in the throttle position sensor are on, so the voltage at the terminal IDL of the engine ECU becomes 0 V. At this time, a voltage of approximately 0.3 - 0.8 V is applied to terminal VA of the engine ECU. When the throttle valve is opened, the IDL contacts go off and thus the power source voltage of approximately 12 V in the engine ECU is applied to the terminal IDL of the engine ECU. The voltage applied to the terminal VA of the engine ECU increases in proportion to the opening angle of the throttle valve and becomes approximately 3.2 - 4.9 V when the throttle valve is fully opened. The engine ECU judges the vehicle driving conditions from these signals input from terminals VA and IDL, and uses them as one of the conditions for deciding the basic fuel injection volume.
