P0EE4 A/C Refrigerant Distribution Valve B Control Circuit Low

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P0EE4 is stored when the control line of refrigerant valve B is pulled to a lower voltage than the driver commands, usually by a short to ground. With a high-side driver the valve would then stay energised or the output would be overloaded; with a low-side driver the coil may be switched on permanently. No manufacturer documents P0EE4 publicly. The closest published case is the valve A sibling P2612, which Ross-Tech describes for Volkswagen models as a short to ground at the N280 compressor regulator valve, a coil of about 10 ohms with a moulded connector that can turn brittle and let the pins corrode. A similar check on the valve B coil and its connector is a sensible start. Open and high faults of valve B are P0EE3 and P0EE5.

Likely causes

Control wire chafed through to ground
Brittle or corroded valve connector
Coil winding shorted to the valve body

Symptoms

  • Warning lamp on
  • Valve B behaves as if permanently energised or not at all
