How to Replace a Throttle Controller

a throttle controller

Most modern vehicles do not have a traditional throttle cable. Instead, they use what’s referred to as electronic throttle controller or throttle actuator control. This system typically consists of a control module, sensors (such as the throttle position sensor and accelerator position sensor) and the throttle actuator. The control module receives input from these sensors. It then uses this information to determine actuator control to open and close the throttle. Common symptoms of a failed throttle controller include poor performance, rough idle, stalling and an illuminated check engine light.
