What NHTSA is examining

The subject vehicles for this investigation include model year 2002 and 2003 excursion and f super duty trucks equipped with 7.3l diesel engines and an optional power adjustable pedal (pap) feature.the subject vehicles utilize an electronic throttle control (etc) system to control engine speed and power.the accelerator pedal position sensor of the etc system was replaced under ford's field service action (fsa) 03b03 (announced in february 2003) due to concerns that it may not operate as designed and as a result, may cause the vehicle to continue to idle or unexpectedly slow when the accelerator is applied.certain complaint and warranty information related to the vehicles involved in fsa 03b03 has not been provided by ford, as discussed in detail in ford's response letter (dated december 2, 2003) to odi's preliminary evaluation information request.this additional information, which is required to adequately assess the safety implications of the alleged defect, will be obtained and analyzed during the engineering analysis phase of the investigation.the manufacturer failure report counts will be determined at that time.
