As with the brake pedal, a sensor of the same type is installed on the clutch pedal. Simply put, this is a kind of limit switch, or as the people call it a frog, which tracks only two positions: the pedal is pressed (contact is closed) and the pedal is not pressed (contact is open). Due to the information received from the SWAG brand Switch, clutch control (cruise control), the ECU automatically adjusts the engine speed. This is important, especially when the vehicle is equipped with cruise control.

The conditions of the clutch control switch usage

Unfortunately, we will not be able to see a sensor malfunction throw the computer diagnostics, since a non-working sensor will not send any signals, the ECU will see that the clutch pedal has not been depressed and will not consider it an error, throwing out the "check". You have to focus only on the behavior of the car, namely at the time of gear shifting. This is especially noticeable when, during a downshift, for example, from 3rd to 2nd, if the revs are high, engine braking occurs and the car literally "pokes its nose" as if braking hard. To make sure that the sensor is 100% operational, while driving, downshift and drop the clutch abruptly.
