P0703, P0704, P0817 and P0830 to P0835: pedal switches and starter lockout
A clutch pedal switch (A or B), the clutch switch input, the second brake pedal switch (B) or the circuit that blocks the starter has a fault.
SeverityModerateUsually not urgent today, but it can get worse if left.

Small switches on the pedals tell the computers what the driver is doing. On a manual car the clutch pedal usually has to be pressed before the starter will turn, and its switch cancels the cruise control and smooths the engine when the clutch is pressed. The second brake switch, B, confirms the main one: the cruise control, the gear lever lock on automatics and stop start systems rely on it. When a switch fails, the car may refuse to start, the cruise control may not engage or cancel, or the lever may not leave park.
What causes P0830?
- A pedal switch out of adjustment, often after pedal or clutch work
- A failed switch or a broken plastic plunger
- A damaged wire or connector above the pedals
- A starter lockout relay or circuit at fault
What to check first for P0830
- Check whether the car starts with the clutch pressed and whether cruise control works
- Check that the brake lights come on when the pedal is pressed
- Inspect the switches above the pedals for adjustment and broken parts
- Watch each switch's state on a scan tool while pressing the pedals
Can you drive with P0830?
If the brake lights work and the car starts, you can drive to a workshop, but do not use cruise control until it is fixed. If the brake lights do not come on, do not drive until they do.
Since May 2018 an engine warning light that stays on is a major defect at the MOT, so the car fails until the fault is fixed.
