P2EBF Battery Charging Mode Switch Stuck

Limp modeNo

P2EBF reports that the control used to select a battery charging mode stays in one state, most likely a button that reads as permanently pressed. On plug-in hybrids such a control makes the engine recharge the traction battery while driving: Mitsubishi's Outlander PHEV had a separate Battery Charge (CHRG) switch that runs the engine until about 80 percent state of charge, and the 2026 model reaches the same mode through its EV button. CARB 13 CCR 1968.2 defines such a driver-chosen mode that raises the state of charge, citing a charge now button as example, and requires distance and fuel used in it to be tracked. No manufacturer documents P2EBF publicly; Mitsubishi's 2023 PHEV code chart lists no such code. A stuck switch can leave the mode on or make it unselectable.

Likely causes

Button mechanically jammed or contact welded in the pressed state
Spilled liquid or dirt in the console switch panel
Short in the switch signal wire imitating a held button

Symptoms

  • Engine keeps running to charge the traction battery
  • Charging mode cannot be switched on or off
  • Higher fuel use and less electric driving
