P2515A/C Refrigerant Pressure Sensor B Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P2515 is the general circuit fault of a second refrigerant pressure sensor, called B. Heat pump systems and vehicles with electric compressors often measure pressure at several points in the circuit; which position is B is up to the maker. Audi bulletin 87 22 35 (November 2022) ties P251500 to refrigerant pressure sensor 2 (G395/G827), read by thermal management module J1024 on 2020–2022 models from A6 to Q8 and e-tron: sensors produced prior to week 31 of 2021 had failing electronics, the cabin stopped cooling, sometimes with P053000 for sensor A as well, and a revised sensor is the cure. Ford's 2014 BOSS 302S engine table lists P2515 without a lamp mark. Low, high and plausibility faults of the same sensor are P2517, P2518 and P2516. Expect weak or absent cooling.
