Throttle Valve Actuator Jammed DetectionThe throttle valve has a component level diagnostic to make sure that the valve is not stuck or sticking in a mannersuch that it cannot reach the desired position. The monitor runs if a jammed valve is not already detected, positioncontrol is in closed-loop control, and adaptive learning is not active. A minimum engine speed is used as an entrycondition.If the position governor deviation is above a maximum calibrated threshold then an output ramp for the detection ofa permanent positive control fault begins. It the output ramp reaches a calibrated threshold then a jammed valvemalfunction is detected. Similarly, if the position governor deviation is below a minimum calibrated threshold thenan output ramp for the detection of permanent negative control deviation begins. If the output ramp reaches acalibration threshold then a jammed valve is detected.Actuator Jammed Valve Check Operation:DTCsMonitor executionMonitor SequenceMonitoring DurationP02EC – Diesel Intake Air Flow Control High Air Flow Detected,P02ED – Diesel Intake Air Flow Control Low Air Flow DetectedContinuousNone10 seconds to register a malfunctionTypical Actuator Jammed Valve Entry Conditions:Entry Condition Minimum MaximumGovernor Active (closed-loop position control)Adaptive Learning Not ActiveJammed Valve Fault Not Present on ActuatorRPM700 rpmTypical Throttle Jammed Valve Check (P02EC/P02ED) Malfunction Thresholds:ThrVlv_rGovDvt > 29.8FORD MOTOR COMPANY REVISION DATE: FEBRUARY 9, 2012 09.01.00.02-PAGE 115 OF 157
