P0EBDA/C Refrigerant Temperature Sensor A Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EBD means the signal voltage of refrigerant temperature sensor A sits at the top of its range. With the usual NTC thermistor that equals an extremely cold reading, and in practice it points to an open signal path, a disconnected plug or a short to the reference voltage. No manufacturer documents P0EBD publicly. As a comparison for the same kind of sensor, GM's 2012 Volt flags its evaporator refrigerant sensor above 98 percent of the 5 V reference (about 4.9 V) in 40 of 50 samples, Type B, under P0538. Mitsubishi's Outlander PHEV treats a high input lasting 4 seconds as an open circuit. A wrong cold value can block compressor operation. The low-voltage counterpart is P0EBE.
- What you may notice
- Compressor stays off or A/C output is reduced
- Implausibly low refrigerant temperature in live data
- Likely causes
- LikelyOpen signal or ground wire, or unplugged connector
- PossibleThermistor open internally
- RareSignal wire shorted to the reference or supply voltage
