Symptoms of Failing Accelerator Cable

Generally, most of the new cars use drive-by-wire electronic throttle control, physical accelerator cables are still commonly found on many cars out on the road.

An accelerator cable is a metal braided cable that serves as a mechanical link between the gas pedal and the engine's throttle plate.

As the throttle controls the power of the vehicle, any issues with the cable can quickly translate into problems with the drivability of the vehicle.

The most common problem associated with the accelerator cable is that they break. In the long run, they simply weaken with age and use, until they eventually snap.

It is also not unusual for them to come out of adjustment, to the point where a noticeable effect is produced, which affects the drivability of the vehicle.

There will be few symptoms displayed when the accelerator cable is having a problem. Damage to the outer covering Delayed accelerator response time Issues with cruise control

Damage to the outer covering

The accelerator cable on most cars is covered by an outer rubber sheath that protects the braided metal cable outside.

Sometimes the cable can come in contact with sharp edges or moving engine components that can wear into the sides of the covering.

If you notice any damage or wear on the covering, then there is a possibility that the metal cable inside has received damage.

As the cable is under constant stress any damage to the cable can leave it more susceptible to breaking.

Delayed accelerator response time

When the gas pedal is depressed, the engine should respond immediately and the vehicle should begin to accelerate.

When you press the pedal if there is delayed response or a significant amount of motion before the vehicle responds, then that is the sign of a problem.

Sometimes, a cable can get stretched over time, which not only delays the response of the throttle but can leave the cable more susceptible to breaking.

Delayed response may also be indicative of the need to have the cable slack adjusted.

Issues with cruise control

Most of the cable operated throttles also use a cable for the cruise control, if you experience any issues while using the cruise control, that may be the sign of a problem.

If you notice any sudden changes in tension from the pedal, such as jerking or binding when you activate the cruise control, that is also a sign of a problem with the accelerator cable.

As both the cables are connected to the same throttle body, any problems with the operation of one can affect the other.

Finally

The accelerator cable is the thing that allows the engine to accelerate, any problems with it can greatly affect the performance of the vehicle.

If you suspect that, you may have a problem with your throttle cable, then have it inspected by a professional technician.
