P0EB6 code meaning
A/C Compressor Motor Phase V Current Sensor Circuit Low
What P0EB6 means
P0EB6 reports that the phase V current signal reads below its permissible minimum. The compressor's power module cannot regulate phase V without it and stops the motor. Candidates are a sensing path pulled to ground, a sensor that has lost its supply or a defect on the inverter board; a problem in the refrigerant circuit cannot produce this code. No manufacturer documents P0EB6 publicly. In the first-generation Chevrolet Volt, GM treated minus 68 A or lower on phase V with the motor at rest as a sensor fault (older code P0D7D, 30 of 60 samples, Type B). Because the sensor is built in, replacing the compressor unit is the normal fix. High range: P0EB5; general V circuit: P0EBB; the phase U and W equivalents are P0EB3 and P0EB9.
P0EB6 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EB6
- No air conditioning
- Fault stored in the compressor control module
Common causes of P0EB6
- PossiblePhase V sensing path pulled to ground
- PossiblePhase V sensor has lost its supply
- PossibleDefect in the V channel of the inverter board
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EB6 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| B6 | The exact fault in that area. |
What to do next
- Note P0EB6 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 P0EB6
What does P0EB6 mean?
P0EB6 means "A/C Compressor Motor Phase V Current Sensor Circuit Low". P0EB6 reports that the phase V current signal reads below its permissible minimum. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EB6?
P0EB6 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0EB6 fail an emissions test?
P0EB6 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 P0EB6 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0EB6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
