P266FA/C Refrigerant Distribution Valve A Control Circuit Driver Current/Temperature Too High
- Generic OBD-II code · Powertrain
- How the car detects it
- Refrigerant distribution valve A is a solenoid that opens or closes one branch of the A/C circuit, for instance a rear evaporator or a battery chiller. Its driver stage in the control module protects itself: when the output current rises above its limit or the chip overheats, it switches off and reports P266F. That usually means the load draws too much, through a shorted coil, a short in the harness or a valve that is mechanically stuck. No manufacturer documents P266F publicly; Ford lists only the open-circuit code P2611 for the same valve, and suppliers such as Egelhof build these shut-off valves as simple on/off solenoids. Unlike P2611 to P2613, which flag open and shorted wiring, P266F concerns the protection of the driver itself. The affected branch then stays closed.
- What you may notice
- One A/C zone or the battery cooling stays inactive
- Fault may return after cooling down
- Likely causes
- LikelyValve coil with shorted turns drawing excessive current
- PossibleShort in the valve harness or connector
- RareValve mechanically stuck so the coil stays loaded
- RareOverheated or defective driver stage in the control module
- Repair
