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.
High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
Symptoms
- Malfunction indicator lamp or hybrid system warning
- Reduced electric drive power or limp mode
- Other drive motor A current or phase codes stored
Most 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
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- It can trigger limp mode.
- It affects emissions.
What each character of P0BFF means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- B: Subsystem depends on the code range
- FF: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0BFF?
If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
What causes code P0BFF?
The most common causes are: 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.
