Accelerator pedal position sensor
APP sensor (accelerator pedal position) is built into the pedal assembly. The sensor is a rotary potentiometer with two tracks.
APP sensor (accelerator pedal position) is housed in a plastic housing that is integrated with the accelerator pedal. The housing is injection molded and provides the ability to install the APP sensor. (accelerator pedal position). The sensor is mounted on the body and secured with two Torx-head screws. On the outer body of the sensor there is a six-pin connector for connection to the vehicle's general electrical network.
The sensor is provided with a centering collar which projects into the housing and provides a pivot point for the pedal mechanism. The centering collar has a slot which allows a pin connected to the sensor potentiometers to rotate 90° when the pedal is moved. The pedal is connected by means of a rod to a drum which is engaged with the sensor pin, converting the rectilinear movement of the pedal into rotational movement. Two steel cables are connected to the drum. The cables are attached to two tension springs which are mounted at opposite ends of the housing. The springs register the movement of the pedal and force the driver to apply a force similar to the force of a cable-operated throttle valve. In the front part of the housing there is a locking mechanism which is actuated by a ball located on the drum. Near the end of the accelerator pedal travel, the ball comes into contact with the locking mechanism. The spring in the mechanism is compressed, as a result of which, at the end of the pedal stroke, the driver feels a press on the downshift switch.
Electronically controlled throttle
The electronic throttle body is located in the intake tract before the point where the tract splits into 2 separate intake manifolds. The electronic throttle is driven by a DC motor and regulates the amount of air entering the intake manifold. This is done in accordance with signals from the engine management system.
Directly after the throttle valve are the EGR valve/cooler lines (exhaust gas recirculation systems) are combined into one node.
