P25EE: Vacuum Pump Control Circuit B / Open
Standardized SAE J2012 code · P25xx — Auxiliary inputs
What does P25EE mean?
The controller cannot drive the secondary electric vacuum pump (B). Brake servo or HVAC actuators that depend on engine vacuum may not get enough vacuum during low-load operation or with engine off in stop-start mode.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Open pump motor winding or worn brushes
- Medium Broken control wire between ECU and pump
