P2773: Four Wheel Drive (4WD) Low Switch Circuit Low
Standardized SAE J2012 code · P27xx — Transmission
What does P2773 mean?
Voltage on the 4WD-Low switch line is below the expected window. Usually a short to ground or a stuck-closed switch.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Switch wire shorted to ground
- Medium Switch stuck in closed position
- Low Connector pins corroded - high contact resistance
