P2D7DCharging Stop Switch Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D7D flags a stop switch signal that jumps between states without a matching button press, or drops out briefly and returns. Since the charging control treats a stop signal as an order to end charging, as both the Toyota and the Honda patents describe, a flickering line can end a session without anyone touching the button. No manufacturer documents P2D7D publicly. Faults that come and go point to a loose terminal, a cracked solder joint in the switch, a chafed wire that touches metal only when the body flexes, or moisture that dries out again. Unlike P2D7A and P2D7B, the measured level is mostly in range, so stored freeze-frame data and a wiggle test are the main tools. Owners typically find that charging stopped overnight for no visible reason.
