P00BBFuel Injector Insufficient Flow - Forced Limited Power
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- 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. P00BB: power has been limited because the injectors do not deliver enough fuel, for example due to coking or wear; low rail pressure or missing injector coding after a replacement have a similar effect.
