What Does P083F Mean?
The PCM has detected that the signals from clutch pedal switch A and clutch pedal switch B do not agree with each other. These two switches are designed to provide redundant confirmation of clutch pedal position. When one switch indicates the pedal is pressed but the other indicates it is released (or vice versa), this correlation code is set.
Common Causes
40%
One of the two clutch pedal switches has failed or is stuck
25%
Misadjusted clutch pedal switch mounting causing different actuation points
20%
Wiring issue on one switch circuit but not the other
10%
Worn clutch pedal pivot or bushings causing inconsistent travel
5%
PCM internal comparison logic fault
Diagnostic Steps
1
Monitor both clutch pedal switch A and B PIDs simultaneously in live data while slowly pressing and releasing the clutch pedal — identify which switch is not toggling correctly.
2
Check that both switches are properly mounted and contacting the clutch pedal arm at the correct engagement points.
3
Test each switch individually with a multimeter for proper open/close operation as the pedal is actuated.
4
Inspect the connectors and wiring for both switches, comparing for damage on one versus the other.
5
Replace the faulty switch; if both appear to work individually, check for a misadjustment issue where one engages earlier than the other.
6
Clear codes and verify both PIDs toggle in sync during a test drive.

The most common cause of P083F (Clutch Pedal Switch "A"/"B" Correlation) is: One of the two clutch pedal switches has failed or is stuck
Typical repair costs for P083F range from $50 to $300, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cruise control disengage and starter interlock safety functions rely on these switches. If one switch has failed, there is reduced redundancy. Safe to drive but repair soon to maintain safety system integrity.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P083F to identify the root cause.
