P0EBCA/C Refrigerant Temperature Sensor A Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EBC is the general circuit fault of the first refrigerant temperature sensor in the air conditioning loop: the control module gets no usable reading from it and does not narrow the fault down to high or low. Volkswagen lists P0EBC00 for the 2021 ID.4 as an electrical fault of refrigerant temperature sensor 1 in the A/C module (address 0008). There the value comes from G395, a combined pressure and temperature sender on the low-pressure line, and bulletin 87-22-01 cures it by replacing that sender, which means draining and recharging the refrigerant. The A/C may stop cooling. Voltage faults of the same sensor are P0EBD and P0EBE, plausibility is P0EBF.
