P261E: Coolant Pump B Control Circuit Stuck On
Standardized SAE J2012 code · P26xx — Computer and output circuits
What does P261E mean?
The second coolant pump runs even when no command is active. Driver is stuck on or the wire is shorted to a permanent supply.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High ECU output driver stuck on
- Medium Control wire shorted to a permanent B+ supply
- Low Carbon or debris buildup preventing free movement
