主副节气门传感器（Main and auxiliary throttle sensor）

主副节气门传感器（Main and auxiliary throttle sensor） LS400 solar term door position sensor - TOYOTA ABS / TRAC anti-skid brake system, throttle position sensor recognition and repair of automobile 2008-04-12 21:56:30 read 254 reviews 0 small subscription number: (1) recognition of TOYOTA ABS / TRAC anti-skid brake system, throttle position sensor ABS / TRAC anti-skid brake system TOYOTA Lexus LS400 car is to turn the engine output torque of the driving antiskid control process in the adjustment of. To this end, the engine body is provided with a solar term door by the acceleration of main throttle pedal control and a stepper motor control of the vice throttle. The stepping motor is not energized, the Deputy keeper solar term in the fully open position, at this time, the air intake of the engine completely through the accelerator pedal manipulation of the main control valve by the pilot section. Main throttle control of engine air-fuel ratio, ignition advance angle and oil cut-off. And in the door body are respectively arranged on the two solar term detection of main and auxiliary throttle position sensor of the solar term door, the detection signal output ECU - ECT control device. ECU - ECT control device and the solar term door opening signal input ABS / TRAC electronic control device. In the ABS / TRAC anti-skid control system without ABS and ASR, brake pressure regulating device and TRAC isolation valve into the total of each electromagnetic are not energized, the brake master cylinder to oil the wheel cylinder in the communication channel, the brake fluid pressure is kept in a certain range, the vice throttle control of stepper motor is not energized, the vice throttle kept open position. In the brake pedal when braking, if in the braking process, the ABS / TRAC electronic control device based on wheel speed signal input to determine the wheel speed sensor wheel to ABS die ABS / TRAC slip prevention control system into the ABS control process. When the wheel speed senso
