Clutch Pedal Switch A/B Correlation
What it means
P083F means the two clutch-pedal switch signals — "A" and "B" — don't agree with each other. The controller uses both to cross-check whether the clutch is pressed, so when one reads pressed while the other reads released it flags a correlation fault. It's a low-severity electrical issue: the engine and clutch operate normally, but functions like cruise control and shift indicators that depend on a trustworthy clutch signal may not work correctly.
Can I keep driving? Safe to drive; the fault mainly affects cruise control and shift-indicator functions, not the engine or clutch itself.

How to diagnose & fix
Work through it in order
- Read live data and compare the A and B clutch switch states through full pedal travel — they should agree.
- Inspect and adjust both clutch pedal switches.
- Check each switch's wiring and connector for damage or corrosion.
- Replace the switch whose signal disagrees with the other.
- Clear the code and retest by cycling the clutch.
