P0D6D A/C Compressor Motor Voltage A Low

P0D6D concerns the high voltage actually reaching the electric A/C compressor motor rather than the sensor circuit: the supply is too low to run it. Mazda documents it for the CX-90 PHEV (2024–2026) and CX-70 PHEV (2025–2026) in bulletin 07-002/26: an overcurrent can short the compressor internally and blow the A/C high-voltage fuse, after which the PCM stores P0D6D, often with U0605. The fix is an updated compressor, followed by a continuity check of the HV circuit including the fuse. Bentley's 2022 Flying Spur Hybrid logs P0D6D00 in thermal management together with an open HV wiring circuit when the HV cable between battery and on-board charger breaks internally; the battery then stops charging as well. The sensor-range code is P0D6B, the high side P0D6E.

Likely causes

Internal short in the compressor that has blown the A/C high-voltage fuse (Mazda)
Broken high-voltage cable in the supply path (Bentley, battery to on-board charger)
Open A/C fuse or poor high-voltage connection without a compressor defect

Symptoms

  • Air conditioning does not cool at all
  • Further codes such as lost communication with the compressor
  • High-voltage battery may not charge (cable fault)
