Throttle valve wire

The throttle valve wire, often called a throttle cable, is a mechanical or semi-electronic link between the accelerator pedal and the throttle body. In older vehicles, it’s a physical cable that opens the throttle when the pedal is pressed, controlling the amount of air entering the engine. In newer cars, the system may be assisted or replaced by electronic throttle control (drive-by-wire).

If the cable is damaged, symptoms may include poor acceleration response, irregular engine behavior, a sticking pedal, or complete throttle failure. Common issues include cable stretch, breakage, fraying, or mechanical binding. These problems can severely affect drivability and safety.

Replacement can be done using new car parts or used car parts, found at an auto parts shop or online car spare parts store. Comparing options via a car parts catalog or online listings helps find affordable components. In urgent situations, a 24-hour auto parts service may be needed. For full reliability, components from the original parts catalog are recommended. It’s also wise to inspect related electrical equipment and engine parts during replacement.
