FORD TAURUS (2003)

Investigation Summary

20130626 Speed control cable damage On June 21, 2013, Ford initiated Customer Satisfaction Program 13B04 to address a concern with Speed Control Cable damage in certain model year (MY) 2000 through 2003 Taurus and Sable vehicles equipped with 3.0L 4V Duratec engines and built at the Chicago assembly plant.In the dealer letter for the program, Ford indicates that the Speed Control Cables on affected vehicles may be susceptible to damage or becoming partially disconnected during under hood vehicle maintenance (e.g., replacing a battery or changing the air filter) and that a damaged Speed Control Cable could interfere with the throttle's full return to idle when the accelerator pedal is released.Ford's program instructs dealers to inspect the Speed Control Cables and replace any with any portion of either collar retention tab missing.Dealers will install a Collar Reinforcement Clip at the Speed Control Cable collar in all vehicles. Figure 1 shows the location of the Speed Control Cable in the engine compartment and the proximity of the battery and air filter.The failure mode of the cable assembly is associated with the plastic collar used to secure the cable to a bracket near the throttle body (Figure 2).Damage to one or both retention tabs used to secure the cable ferrule within the collar may allow the ferrule to become disconnected from the collar when the throttle is opened during accelerator pedal application.Additional examples of Speed Control Cables with damaged collar retention tabs and partial ferrule displacement are shown in Figures 3 through 5.If the displacement pulls the ferrule completely out of the collar, the ferrule end may contact the face of the collar when the accelerator pedal is released and the throttle is returning to idle (Figure 6).This results in a throttle stuck at approximately 26-29% open.Testing conducted at NHTSA's Vehicle Research and Test Center found that brake booster vacuum may become depleted, resulting in reduced brake effectiv
