Reported risk: On certain vehicles equipped with an INTERNATIONAL® VT365 engine, the engine calibration normally responds to a failed open accelerator position sensor circuit fault by returning the engine to low idle speed of 800 rpm and disabling the driver's ability to increase the engine speed. However, If the open circuit condition corrects itself within 30 seconds of its initiation the engine calibration misinterprets this event by going into a "limp home mode" where the engine speed is increased from low idle speed to the high idle speed of 1200 rpm. This increase to high idle speed may occur without warning causing a sudden and unexpected shift in vehicle position possibly resulting in property damage, personal injury or death. Correction: Dealers will install an updated engine calibration.
