P0D81Battery Charger Input Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D81 is the plausibility code for the charger's AC input: a signal is present and electrically valid, yet contradicts the stage the charging sequence has reached. No manufacturer documents this code publicly with thresholds. A Ford patent on charger-to-EVSE detection outlines the kind of check meant here: the charger watches for line voltage while its S2 switch is still commanded open, debounces the condition and may only report it after it recurs over several charge cycles. Such a mismatch typically comes from a station that energises its contacts too early. CARB does not require faults caused by the off-board supply to be told apart, so the code often points at the EVSE rather than the car. P0D80 covers missing input, P0D82 and P0D83 electrical out-of-range values, P0D90 a wrong frequency.
- What you may notice
- Charging does not start or stops shortly after plugging in
- Charging fault message
- Likely causes
- LikelyCharging station switches AC on before the vehicle has closed S2 (faulty or welded EVSE relay)
- PossibleCharger's input voltage measurement reports an implausible value
- RareImprovised supply that feeds the inlet directly without a proper EVSE
- Repair
- Medium · Usually a job for a workshop.Typical cost: €0 – €1,800
