P0BFF is the general code for the current flowing through drive motor A, the electric machine the manufacturer labels A. It covers a current fault that is not classed as too low (P0C00) or too high (P0C01). No manufacturer documents this exact code publicly. CARB requires hybrids to monitor electric motor performance. The closest documented check is GM's P0C01, which compares the sensed phase current with a fixed limit, and Stellantis lists P0C01 on the 2026 Wagoneer S with damaged three-phase cabling as the cause. A stored P0BFF means the motor controller no longer trusts the motor current, so it usually reduces electric drive power. Check the three-phase connections, the motor windings and the inverter.

Likely causes

Loose, corroded or damaged three-phase cable joint between inverter and motor A
Fault in the motor A inverter or its current measurement
Damaged stator winding of drive motor A
Motor control software fault

Symptoms

  • Malfunction indicator lamp or hybrid system warning
  • Reduced electric drive power or limp mode
  • Other drive motor A current or phase codes stored
