Modular throttle position sensor

Modular throttle position sensor(A) structural features modular TPS Toyota car uses modular throttle position sensor as shown in Figure 2-35a, the principle of the circuit shown in Figure 2-35b. It mainly consists of a variable resistor and the sliding contacts, throttle shaft, idle contact, shell composition. Variable resistor film resistor formed on Crankshaft Sensor board, the variable resistor wiper rotates together with the throttle shaft, sliding arm connected to the output terminal VTA. (2) Combined Combined TPS TPS output characteristics of the output characteristics shown in Figure 2-36. When the throttle is closed or opening is less than 1.2. When the idle contact is closed, its output terminal IDL output low (0V); when the throttle opening is greater than 1.2. When the idle contact is disconnected, the output terminal IDL output high (5V). When the throttle opening change, the variable resistor wiper will immediately rotate the throttle shaft, will be in sliding contact arm slides on film resistor, the Position Sensor output terminal VTA and E, the signal voltage between the ensuing change, as shown in Figure 2-35, the greater the throttle opening degree, the higher output voltage. The linear sensor output signal after A / D converter into a digital signal and then enter the ECU.
