Acceleration Control

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

On gasoline engines the throttle is controlled by an accelerator cable attached to the accelerator pedal and shaft. The accelerator pedal and shaft should travel smoothly from the idle to the wide open throttle positions. Hesitation on return or prevention of return to the idle position must not occur. Surrounding components such as wiring, hoses, sound insulator and floor carpet must not contact the sliding inner member of the accelerator cable or the accelerator pedal and shaft. The throttle assembly is not adjustable.

The diesel engine does not use an accelerator cable. Instead, the diesel engine uses an accelerator sensor assembly located on the accelerator pedal assembly. This drive-by-wire system is entirely electronic and, except for the accelerator pedal assembly, does not use mechanically moving parts. The accelerator sensor assembly is not adjustable.

The adjustable accelerator pedal is driven by a cable connected to a motor mounted on the brake pedal assembly. The driver adjusts the pedal position by operating a switch mounted in the instrument panel.
