P00BB Fuel Injector Insufficient Flow - Forced Limited Power
One or more injectors deliver less fuel than commanded — ECU has activated forced power reduction. A flow-deviating injector throws off cylinder balance — adjacent cylinders run leaner/richer to compensate, often masking the root cause until the trim limit is hit.
Is it safe to drive with P00BB?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
