P0EE3 A/C Refrigerant Distribution Valve B Control Circuit/Open

P0EE3 concerns the wiring between the controlling module and refrigerant valve B, most often an interrupted path. With the output switched off, the driver normally sees a defined voltage through the coil; with it switched on, current flows. If neither picture appears, for instance because a pin has backed out of the connector or the coil winding is broken, the circuit is declared open. No manufacturer documents P0EE3 publicly. That valve B exists as a separately monitored part is shown by Audi's A7 PHEV, whose thermal management unit J1024 reports its mechanical fault as P0EE200. Typical hardware is a 12 V solenoid like Egelhof's shut-off valves. CARB requires every electronic output used for battery thermal management to be checked for open circuits. The matching valve A code is P2611.

Likely causes

Loose, corroded or pushed-back pin at the valve connector
Broken coil winding in valve B
Broken wire in the harness to the valve

Symptoms

  • Warning lamp on
  • Valve B no longer switches, affected refrigerant branch stays as it is
