P0EBB code meaning
A/C Compressor Motor Phase V Current Sensor Circuit
What P0EBB means
P0EBB is the general circuit code for the compressor's phase V current sensor, numbered after the W-phase codes instead of at the start of the V series. The module receives no usable V-phase value at all and does not classify it further as high, low or implausible. Without that value the field-oriented control of the three-phase motor cannot work, so the drive stops. No manufacturer documents P0EBB publicly. GM's 2011 Volt monitored the phase sensors of its compressor at standstill under older codes (P0D7C and P0D7D for phase V, plus or minus 68 A, Type B). Causes are an open sensing path, a loose internal plug or a failed sensor or board. Detailed V-phase faults are P0EB5 to P0EB7; the general U and W circuit codes are P0EB1 and P0EC0.
P0EBB 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 P0EBB
- Compressor does not run
- Air conditioning and possibly battery cooling unavailable
Common causes of P0EBB
- Most likelyFailed phase V sensor or inverter board
- PossibleOpen phase V sensing path
- Less likelyLoose internal plug between sensor and board
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EBB means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| BB | The exact fault in that area. |
What to do next
- Note P0EBB 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 P0EBB
What does P0EBB mean?
P0EBB means "A/C Compressor Motor Phase V Current Sensor Circuit". P0EBB is the general circuit code for the compressor's phase V current sensor, numbered after the W-phase codes instead of at the start of the V series. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EBB?
P0EBB does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0EBB fail an emissions test?
P0EBB 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 P0EBB to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0EBB clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
