P2D84Battery Charger B Input Current Sensor Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D84 is the high-side fault of charger B's input current sensor: its signal climbs above what the measuring range allows. No manufacturer documents P2D84 publicly, so the A-side code P0D3B serves as reference. For the 2022 Outlander PHEV, Mitsubishi counts half a second of sensor output above 4.658 V (around +54 A) as a supply-side short and halts charging. GM's Volt module of 2011 sets its Type A fault once more than 24.78 A of AC is reported in 160 out of 200 ms. Real currents of that size would exceed what the charger draws by design, so the fault almost always lies in the measuring chain. P2D84 differs from P0E89, where the current is judged too high, not the sensor. Low counterpart: P2D83.
