Fuel Cutoff Mode

In order to prevent possible engine damage from over-speed, the Control Module cuts OFF fuel from the fuel injectors when the engine speed is above approximately 5500 RPM with the vehicle in any forward gear or reverse. In order to prevent tire damage, the Control Module also has a fuel cutoff in excess of 108 mph (173 km/h) based on the speed rating of the tires.

Fuel is also Cutoff during rapid deceleration. See Deceleration Mode.
