P0EBE code meaning
A/C Refrigerant Temperature Sensor A Circuit Low
What P0EBE means
P0EBE is logged when the voltage from refrigerant temperature sensor A falls close to zero. For an NTC element a low voltage stands for high temperature, so the controller sees refrigerant that seems far too hot. Real heat at that level is unlikely; a signal wire chafed through to ground or a thermistor shorted internally is the usual finding. No manufacturer publishes P0EBE. GM's 2012 Volt reacts to its evaporator refrigerant sensor below 2 percent of the reference (about 0.1 V) in 40 of 50 samples as P0537, Type B, which shows how such a check is built. Expect the compressor to be held off as protection. High-voltage fault of this sensor: P0EBD.
P0EBE at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EBE
- A/C compressor switched off as a precaution
- Live data shows an unrealistically hot refrigerant
Common causes of P0EBE
- Most likelySignal wire chafed and shorted to ground
- PossibleThermistor shorted internally
- Less likelyMoisture bridging the connector pins
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EBE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| BE | The exact fault in that area. |
What to do next
- Note P0EBE 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 P0EBE
What does P0EBE mean?
P0EBE means "A/C Refrigerant Temperature Sensor A Circuit Low". P0EBE is logged when the voltage from refrigerant temperature sensor A falls close to zero. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EBE?
P0EBE does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0EBE fail an emissions test?
P0EBE 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 P0EBE to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0EBE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
