What causes the clutch switch failure in a Jetta car?
1 Answers
Mainly due to the wear and tear of the normally closed copper piece in the switch, which can easily break and fail to close. The clutch switch is a normally closed switch that provides 12 volts to the engine control unit. When the clutch is depressed, the switch opens. Additional information: 1. Function of the clutch: Ensures smooth starting of the car, enables smooth gear shifting, and prevents overload of the transmission system. 2. Working principle of the clutch: (1) The clutch is installed between the engine and the transmission, serving as the component in the car's transmission system that directly connects with the engine. Typically, the clutch is mounted together with the engine crankshaft's flywheel assembly, acting as the part that cuts off and transmits power between the engine and the car's transmission system. From starting to normal driving, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and the transmission system, thereby cutting off or transmitting the power output from the engine to the transmission system. (2) Its role is to allow gradual engagement between the engine and the transmission, ensuring smooth starting of the car; temporarily cutting off the connection between the engine and the transmission to facilitate gear shifting and reduce impact during shifting; and acting as a separator during emergency braking to prevent overload of the transmission and other drive systems, thus providing a certain protective effect.
