Gas pedal

nounStandard termAutomotive

The foot-operated control that regulates the engine's power output and vehicle speed.

The floor-mounted pedal on the right side of the driver's footwell that controls the engine's throttle. In older vehicles, it uses a mechanical cable to pull the throttle body open. In drive-by-wire systems, it uses electronic position sensors to signal the engine control unit, which then adjusts fuel and air delivery to increase speed.

Heard on the job

The gas pedal feels sticky, so check the throttle cable routing near the firewall.
