What P0EE6 means
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.
P0EE6 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EE6
- Warning lamp on
- Valve B switched off, cooling branch not served
Common causes of P0EE6
- Most likelyShorted turns in the valve B coil raising the current
- PossiblePartial short in the valve wiring
- Less likelyControl module output stage overheating
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EE6 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| E6 | The exact fault in that area. |
What to do next
- Note P0EE6 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0EE6
What does P0EE6 mean?
P0EE6 means "A/C Refrigerant Distribution Valve B Control Circuit Driver Current/Temperature Too High". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EE6?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0EE6 fail an emissions test?
P0EE6 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0EE6 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0EE6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
