FBC operates in closed-loop control in an engine speed range of 500-1150 RPM, and a commanded injectionquantity of 3.5 – 50 mg/stroke. The maximum allowed correction in fuel quantity for an individual cylinder is givenby the following table.CSER Component Monitor: Cold FBC Control Limits:Injection quantity requested before FBC correction (mg/stroke)3.5 7.5 30Maximum allowable FBC correction(mg/stroke):0.5 5 10When the current correction for a given cylinder exceeds 99% of the allowable correction for the current conditions,a code is set.FORD MOTOR COMPANY REVISION DATE: FEBRUARY 9, 2012 09.01.00.02-PAGE 72 OF 157
