1 Answers
Abnormal clutch switch signals can be caused by wiring issues or a faulty clutch switch. Below are detailed explanations: Wiring Issues: Clutch switch signal malfunctions are often due to wiring problems. It is recommended to inspect and repair the wiring. The clutch switch is a normally closed switch that supplies 12 volts to the engine control unit. When the clutch is depressed, the switch opens. If the engine control unit does not receive the clutch signal, it interprets this as a command to disconnect the engine, thus reducing the ignition timing advance to decrease fuel injection and power reserve, preventing gear shift shock. Faulty Clutch Switch: If the clutch switch is damaged, symptoms such as jerking or the vehicle not accelerating may occur. In this case, replacing the clutch switch is advisable.
