P0A95High Voltage Fuse A
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- P0A95 means the battery management detects that a fuse in the high-voltage circuit has opened, usually by comparing the voltage before and after the fuse. Several makers document it: Jaguar for the I-PACE battery energy control module, where a shorted high-voltage auxiliary component blows fuses in the junction box and battery module; Porsche for the Taycan as the main high-voltage fuse with a vehicle that will not become ready to drive; Volvo, whose procedure compares the voltage after the fuses with pack voltage; and Audi, which found an intermittent false entry in hard cornering fixed by software. P0E2F and P0E30 cover fuses B and C. Mostly the car cannot be driven until the cause is found.
