P2DF5: Coolant Pump E Control Circuit Low
Standardized SAE J2012 code · P2Dxx codes
What does P2DF5 mean?
Coolant pump E reports a control circuit low condition. Coolant circulation through the affected loop cannot be commanded reliably.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Pump motor or driver fault
- Medium Wiring or connector fault
- Low Connector pins corroded - high contact resistance
Likelihood is a general estimate across vehicles; your make and model may differ.
