2PE11018 · Idle Instability
Opened May 11, 2011 · Closed Feb 7, 2013
Status: closed (inferred from source dates) · Vehicle Speed Control
On November 29, 2012, Ford Motor Company (Ford) initiated Customer Satisfaction Program 12N03 to extend warranty coverage terms for repair of engine idle RPM surge caused by throttle body deposits in all model year (MY) 2005 through 2007 Ford Freestyle, Five Hundred and Mercury Montego vehicles.The program extends the coverage for up to 10 years of service or 150,000 miles from the warranty start date of the vehicle (all vehicles are eligible for the program through May 31, 2013, regardless of mileage).Dealers will repair vehicles exhibiting the condition by removing and cleaning the throttle body and reprogramming the PCM with software containing an updated idle speed control strategy.According to Ford, some of the affected vehicles may experience momentary, intermittent engine idle RPM surge (idle flare) when stopped or during low speed driving maneuvers such as in a parking lot or driveway.Unstable idle speed control (dips and flares) around the target engine speed (700 rpm) can occur in vehicles with deposit build-up in the throttle body when the system adjusts engine speed in response to changes in engine load, typically from power steering application or air-conditioner compressor cycling.Idle speed control logic is only active at vehicle speeds below 3.5 mph and when the accelerator pedal is not applied.Ford testing of a vehicle with a worst case throttle body measured a maximum idle flare of 1360 RPM lasting approximately 1 second, which Ford indicated was consistent with system design to limit vehicle speed and acceleration in idle control mode.Ford indicated that the test vehicle was held in place with normal brake effort and that vehicle speed remained under 4 mph without the brake pedal applied.In addition to throttle body deposit accumulation, symptoms associated with the condition may include Check Engine lamp illumination and diagnostic trouble codes (DTCs) P0505, P0506 or P061B.Ford attributed the surge condition to changes in idle air flow resulting from the progressive buildup of deposits in the throttle body from normal Positive Crankcase Ventilation (PCV) system operation.This condition was not adequately compensated for in the original Powertrain Control Module (PCM) calibration.Ford issued a technical service bulletin on August 15, 2011 (TSB 11-8-5), releasing an updated powertrain control calibration for vehicles with CVT transmissions.On October 19, 2011, Ford issued a second bulletin (TSB 11-10-21) superseding TSB 11-8-5 and including updated powertrain control calibration for vehicles with 6-speed transmissions.Prior to Ford issuing the TSB?s, owner?s experiencing the alleged defect either received no repairs, if dealers could not duplicate the condition, or had the throttle body cleaned or replaced, which only provided temporary correction until the throttle deposit build-up returned.Ford?s revised powertrain calibrations appear to be effective remedies for the idle instability caused by build-up of throttle body deposits.However, even after the TSB?s were released, many owners experiencing the condition continued to have difficulty with proper diagnosis and repair as dealers were often either unable to duplicate the condition or were unfamiliar with the new repair procedures.Ford's new program addresses those concerns.NHTSA's testing and complaint analysis indicate that the idle speed control issue in the subject vehicles can only occur at very low speeds, are very brief events, are easily controlled by moderate brake pedal forces and result in minor increases in vehicle speed even with no braking.This investigation is closed.The closing of this in

THE SUBJECT VEHICLES EXPERIENCE A LOSS OF PROPER INSTRUMENT CLUSTER OPERATION.TYPICALLY, THE PROBLEM APPEARS AS THE NEEDLE ON THE GAUGE (SPEEDOMETER, TACHOMETER, FUEL, AND/OR TEMPERATURE) SWEEPS AND RESETS INTERMITTENTLY.FORD REPORTS THE PROBLEM AS MOMENTARY POWER INTERRUPTION CAUSES THE GAUGES TO SWEEP AND THEN RECOVER TO NORMAL FUNCTION.IN AUGUST 2006, FORD ISSUED A TECHNICAL SERVICE BULLETIN (TSB 06-17-9) TO PROVIDE GUIDELINES TO SERVICE TECHNICIANS FOR DIAGNOSIS AND REPAIR OF THIS CONDITION.ODI'S REVIEW OF FORD'S RESPONSE TO THE AGENCY'S INFORMATIONREQUEST LETTER REVEALS THAT THE MAJORITY OF THE REPORTS TO FORD (63%) INDICATE THAT THE INSTRUMENT CLUSTER WOULD EXPERIENCE INTERMITTENT LOSS OF POWER.FORD REPORTS THAT THISLASTS FOR ONLY A FEW SECONDS.ALSO FORD STATES, THE VEHICLE'S EXTERIOR LIGHTING WOULD NOT FAIL TO ILLUMINATE EVEN IN THE EVENT OF POWER INTERRUPTION TO THE CLUSTER BECAUSE THE EXTERIOR LIGHTS ARE POWERED SEPARATELY AND DO NOT RELY ON ANY SIGNAL FROM THE CLUSTER.ADDITIONALLY, ODI CONTACTED COMPLAINANTS WHO AFFIRMED THE INTERMITTENT CONDITION AND THAT NONE OF THE EXTERIOR LIGHTS ON THE SUBJECT VEHICLES WOULD BE AFFECTED BY POWER INTERRUPTIONS TO THE INSTRUMENT CLUSTER.ODI LAST RECEIVED A REPORT REGARDING THIS ISSUE IN AUGUST OF 2007.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME.ODI WILL HOWEVER CONTINUE TO MONITOR THE ISSUE AND WILL TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.
