Description of DTC code P0830

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.

Symptoms of fault code P0830

  • Check Engine light comes on.
  • The engine does not start.
  • Engine start occurs without engaging the clutch.

Causes of OBD2 P0830

The P0830 OBD2 fault code is set by the following:

  • Clutch Position Sensor Switch wires could be in poor condition.
  • Connections or a fuse in the circuit may be faulty.
  • The Clutch Position Sensor Switch may be faulty.

Possible solutions of the DTC code P0830

In order to troubleshoot the DTC P0830 OBDII code, consider the following:

  • Consult the TSBs as a first step.
  • Check if the cables and connectors associated with the Clutch Position Sensor Switch are in good condition. If you discover deficiencies created by wear or burns, proceed with the appropriate adjustments.
  • Perform electrical tests on the Clutch Position Sensor Switch circuit. Although these tests are vehicle specific, note that with the clutch disengaged there should be approximately 12 volts on one side of the switch. By the time the clutch engages, the voltage should be present on both sides of the switch. Furthermore, the starter solenoid or starter motor should also have power as indicated by the manufacturer. If you discover power or ground deficiencies, check the continuity of the wiring. Repair it as applicable.
  • Verify the integrity of the Clutch Position Sensor Switch by following the manufacturer's recommendations. If you determine that it does not meet specifications, consider replacing it.
