P083F Clutch Pedal Switch A/B Correlation
Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo
Manual cars often carry two clutch pedal switches: one near the top of the pedal travel for cruise control and start-stop, one near the floor that releases the starter. Pressing the pedal must switch them in a sensible order; P083F means their states contradict each other. Stellantis documents it for the 2025 Jeep Wrangler manual: the engine does not crank and start-stop is blocked, caused by corroded contacts in the clutch interlock switch, which is replaced. Ford checks the same pair over more than 40 pedal applications but reports it as P0704, without MIL.
Likely causes
One clutch switch faulty or corroded
Switch misadjusted or not seated after clutch or pedal work
Open circuit or contact resistance in harness or connector
Pedal does not fully return (stop, hydraulics)
Symptoms
- Start-stop not working
- Engine does not crank although the clutch is pressed
- Cruise control cannot be set
