P0D84Battery Charger Input Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D84 stands for an input signal that keeps jumping or dropping out during a charge rather than sitting steadily at a wrong value. There is no public manufacturer description of the code. In practice such patterns come from contacts that make and break: a worn or loose charging plug, a heat-damaged inlet socket, a cable damaged by being driven over, or a loose connector between inlet and charger. A supply that sags under load, such as a long extension lead, can look the same. The Ford P0D80 check with its 30-second debounce shows how short dropouts are filtered before an open circuit is declared; P0D84 catches what remains unstable. Charging may stop and restart repeatedly, take longer than usual or abort without a clear pattern.
