Clutch Pedal Switch "A" Circuit
Severity
low
Lowest on our scale. Fix it when convenient.
Can you drive it
Only if running normally
A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety.
Indicative cost (USD)
$50–$200

Manual-transmission clutch-pedal switch input fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0830 sets when the TCM or PCM cannot read a coherent state from clutch pedal position switch A, the upper or top-of-travel switch used on manual transmissions for cruise-control disengage, starter inhibit, and on hybrids for engine-restart logic.
Start with the cheapest checks
verify the pedal returns fully to its rest stop (worn carpet edges and aftermarket floor mats are routine culprits), then unplug the switch and ohm it across the two signal pins while pressing the pedal slowly. A good A-switch reads open circuit (over 100 kilohms) pedal up and under 1 ohm pedal fully depressed, with a single clean transition; any double-click or chatter during the press is a failed switch. Caveat: many platforms share the A circuit with the brake-light or starter-relay logic, so a complaint of no-crank or cruise drop-out alongside P0830 points to the switch.

- 2008-2013BMW E90/E92 M3 with the rare 6-speed manual sees the upper clutch switch fail at around 60-80k miles, blocking the engine restart on iDrive-equipped cars and tripping P0830.
- 2011-2016Ford Fiesta and 2014-2019 Focus ST manual transmissions have a plastic pedal-bracket tab that cracks and lets the switch float, generating an intermittent P0830 cured by bracket and switch together.
- 2010-2015Chevrolet Camaro SS 6-speed throws P0830 when the switch internal contacts pit from repeated track-day launches.
- 2012-2018VW Golf and GTI manuals (MQB platform) frequently log P0830 from a broken wire at the firewall grommet rather than a bad switch.
Estimated repair$90 to $320.

P0830 — frequently asked
What does a P0830 code mean?
Manual-transmission clutch-pedal switch input fault.
What causes a P0830 code?
Common causes: Failed switch; Mis-adjusted switch; Wiring.
What are the symptoms of a P0830 code?
Typical symptoms: Cannot start (clutch interlock); Check engine light; Cruise control inop.
Is it safe to drive with a P0830 code?
Only if running normally. A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety. Estimated repair: $50-$200.
How do I diagnose a P0830 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
