P2A36: AFCM Power Relay Sense Circuit Low
Standardized SAE J2012 code · P2Axx codes
What does P2A36 mean?
The sense feedback voltage from the AFCM power relay is below the expected window. Indicates the relay output stays low when the relay is commanded on.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Relay contact stays open
- Medium Feedback wire shorted to ground
- Low Connector pins corroded - high contact resistance
