P2D82Charging Start Switch Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D82 describes a start switch signal that toggles on its own or vanishes for moments. Because a start command is a trigger rather than a stop order, the visible effect is different from P2D7D: a flickering contact may start a charging session nobody asked for, for example ahead of a cheaper overnight tariff set in the timer, or swallow a deliberate press. No manufacturer documents P2D82 publicly; the switch type is known from Honda's and Toyota's patents, where turning the start switch on begins charging. Loose terminals, cracked solder joints, switch bounce on worn contacts and moisture that comes and goes are the usual reasons. The stored level is often in range, so watching the live switch status while moving the harness and pressing the key is the practical test.
