P0EE5A/C Refrigerant Distribution Valve B Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0EE5 means the control line of refrigerant valve B carries more voltage than its commanded state allows. If the driver switches the coil to ground, a short to a 12 V feed is the classic reason; with some driver types an open coil can also float the line high. The practical effect depends on whether valve B is normally open or normally closed: either it cannot be energised any more, or it is energised when it should rest. No manufacturer documents P0EE5 publicly. Audi's A7 PHEV shows that valve B is watched by its own thermal management unit (J1024), and automotive shut-off valves of this kind run on 12 V or 24 V coils, according to Egelhof. CARB requires electrical checks of such battery thermal management outputs. P0EE4 is the low counterpart, P2613 the valve A code.
