P00BB Fuel Injector Insufficient Flow - Forced Limited Power
Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible
"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.
Likely causes
Injectors coked or worn (flow drift)
Fuel contamination
Rail pressure too low
Injector coding missing after replacement
Symptoms
- Check engine light on
- Marked loss of power, limp mode
- Rough running
