P0D29Battery Charger Input Current Too Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D29 is set when the on-board charger draws less AC current than expected for the power it was asked to deliver, while voltage and charging permission are present. No manufacturer documents P0D29 publicly. Related tests show how such a check is built: GM's Volt compares the AC input current with fixed limits for the high side (P0D2A), and Mitsubishi first verifies that the input current sensor reads plausibly before trusting it (P0D39). A low current with normal voltage points to a charger that does not ramp up, high resistance at the inlet or cable, an EVSE that limits current, or a measurement fault. CARB requires charger faults that limit the charging rate to be detected. Charging is slower than usual or stops. Too much current is P0D2A, voltage problems P0D27/P0D28.
