The throttle position sensor (TPS) is a device that sends a signal to the controller about the position of the throttle valve. The meter also serves to meter fuel and select the fuel delivery mode. Sensors are of two types - contact and non-contact, differing in the principle of operation.

In the design of almost all modern vehicles, wide varieties of electronic devices are provided. Thanks to these details, various functions, control and adjustment of units, assemblies and systems are carried out. One of such devices, simple in design, but critical for a car, is the TOPRAN brand Sensor, throttle position or simply TPS.

The conditions of the throttle position sensor usage

If you find that this sensor is defective, it should be replaced as soon as possible. Otherwise, expensive repairs to an internal combustion engine are just a matter of time.

The key function that the TPS sensor performs is to transmit information about the overflow valve to the electronic control unit of the motor: whether it is open or closed. By design, it can vary significantly if you compare this part from different vehicles.
