Alfa Romeo Accelerator cable replacement

Alfa Romeo Accelerator Cable Replacement

Most modern Alfa Romeo’s now use drive-by-wire technology instead of mechanical systems. This includes the accelerator cable, with vehicles now utilising electronic throttle controls to replace mechanical linkages. However, the accelerator cable is not completely dead just yet, and there are still plenty of Alfa Romeo’s on the road with this venerable mechanical component.

The accelerator cable is a braided, flexible, metal cable that can get damaged or fail over time. If it does fail, you may notice a change in acceleration and there may be a delay when you push the accelerator pedal down on your Alfa Romeo. If the cable breaks for any reason you won’t be able to accelerate at all.

An accelerator cable is a fairly simple device. A cable runs from the accelerator pedal to a spring-loaded linkage on the throttle body. When a driver pushes the accelerator pedal down, the cable moves the linkage on the throttle body. This opens the valve on the throttle body to allow more air to flow into the Alfa Romeo’s engine. The position of the foot on the accelerator pedal determines the airflow and the amount of fuel going through the injectors to provide the optimal air/fuel mixture for engine combustion.

It may not seem like a big inconvenience but making sure you can accelerate when required can become an important part of getting out of trouble quickly, you never know how much you rely on that accelerator working on the Alfa Romeo, until you really need it.

Ensuring you can accelerate when required is actually a pretty important safety issue - you may need to move quickly to avoid an accident - and if the accelerator cable on your Alfa Romeo breaks, you could find yourself in trouble. If it does break, at the very least you’ll find yourself stuck at the side of the road summoning a tow truck.
