Through circuit A of the Clutch Pedal Switch, the PCM (Powertrain Control Module) can control the position of the clutch pedal by reading the output voltage from the Clutch Position Sensor. The design of the Clutch Position Sensor Switch varies by manufacturer but is generally a basic on/off switch located near the clutch pedal. Voltage from the switch is usually present on one side of the switch and the contacts are closed when the clutch pedal is activated which transfers voltage to the starter motor or starter solenoid. The basic function of this switch and its circuitry is to prevent the engine from starting before clutch engagement.
When the diagnostic code P0830 OBDII is stored, it is because a malfunction was detected in circuit A of the Clutch Pedal Switch. It is important to note that although this code is of moderate severity, starting the vehicle with the clutch disengaged creates a safety problem.
