P0D6CA/C Compressor Motor Voltage Sensor A Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D6C covers a voltage-sensor signal from the electric A/C compressor that jumps or drops out briefly instead of staying wrong: single readings outside the expected window or abrupt steps that do not last long enough for the low or high code. No manufacturer documents P0D6C publicly. GM (Volt, ELR) and Mitsubishi (Outlander PHEV) monitor the same input but only publish P0D69 (comparison with battery voltage), P0D6A and P0D6B, each with fixed fail counts such as 30 of 60 samples or 2 s. CARB requires the sensor inputs of hybrid thermal-management parts, which include a compressor that also cools the battery, to be checked for circuit and rationality faults. Loose low-voltage plugs, a marginal HV contact or a failing inverter board are typical; cooling may cut in and out.
- What you may notice
