P0EBFA/C Refrigerant Temperature Sensor A Range/Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
How the car detects it
P0EBF reports that sensor A gives an electrically valid but implausible refrigerant temperature. Three makers name it. Audi stores P0EBF00 as passive or sporadic in the Climatronic module of the 2016 A3 e-tron; bulletin 2047037 blames a miscalculation in the refrigerant self-check and points to TSB 2046942. VW's 2021 ID.4 links it to the G395 sender, which is replaced. Volvo logs P0EBF24 in the engine module of its 2017 to 2019 S90, V60, XC60 and XC90, lighting the check engine lamp: when the car had been pre-heated or pre-cooled, or started remotely, while the traction battery was charged, the software misjudged the sensor, and Technical Journal 34446 ends with a software update. Circuit faults are P0EBC to P0EBE.
What you may notice
  • Check engine lamp on (Volvo) or MIL requested by the climate module (Audi)
  • Fault stored as intermittent or sporadic
  • A/C may cool poorly or not at all
Likely causes
  • LikelySoftware misjudgement after preconditioning or self-check (Volvo, Audi; update available)
  • PossibleDeviating pressure/temperature sender (VW G395)
  • RareWrong refrigerant charge distorting the comparison values
