- Generic OBD-II code · Powertrain

- Can trigger limp mode
- How the car detects it
- "Forced limited power" is a term for a protective strategy in which the engine control module deliberately limits engine power. Regulations require the check engine light to come on within seconds when such an emissions-relevant limp-home mode is active. These codes report the reason for the limitation; usually further codes point to the actual cause. No manufacturer description naming this exact code was found. P00BA: power has been limited because fuel pressure is too low, which protects the engine and the pump against running lean or losing rail pressure.
