P0EE6A/C Refrigerant Distribution Valve B Control Circuit Driver Current/Temperature Too High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0EE6 is reported by the output stage itself: the switch that powers refrigerant valve B has measured too much current or got too hot and has protected itself. Modern smart high-side switches do this on chip; TI's TPS1HB16-Q1, for example, has an adjustable current limit between 4.4 and 49 A, shuts down at about 150 C junction temperature with roughly 20 C hysteresis, and flags the event on its diagnostic output. A coil drawing more current than normal, through shorted turns or a partial short in the wire, is the usual cause; a hot mounting spot of the module can add to it. No manufacturer documents P0EE6 publicly. Unlike P0EE4, the circuit still conducts and is not simply grounded. The same driver fault on valve A is P266F; Audi's A7 PHEV logs a valve B fault in J1024.
