Standardized SAE J2012 code · P2Dxx codes
What does P2D92 mean?
The current sensor for starter/generator phase X reports voltage above the expected window. Indicates short to B+ or sensor offset drifted high.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Signal wire shorted to B+
- Medium Sensor offset drifted high
- Low Connector pins corroded - high contact resistance
