Electronic Throttle Controls

Our range of ETCs (Electronic Throttle Control systems) are suitable for light, medium, and heavy commercial vehicle applications for both on- and off-highway use. These include medium- and heavy-duty trucks, buses and motor coaches, construction and agricultural vehicles, material handling, and other specialty vehicles.

Three distinct styles are available: floor-mounted electronic pedals, suspended electronic pedals and thumb-operated electronic throttle controller.

These products incorporate the latest non-contact hall-effect sensing technology to provide a durable, rugged, and reliable drive-by-wire signal for the vehicle’s electronic fuel management system or the motor controller for battery-powered vehicles. The sensors are compatible with all the major engine manufacturers and provide a combination of APS and IVS signals which can be factory configured to suit individual applications.

Electronic Throttle Controller Purpose

An electronic throttle control system is an automobile technology that electronically connects the accelerator pedal to the throttle. The electronic throttle control system usually includes three components: a throttle valve that can be opened and closed by an electric motor, an accelerator pedal module, and a powertrain or engine control module. The embedded system uses software to determine the required throttle position by calculations from data measured by other sensors.  

Electronic Throttle Controller Benefits

Although benefits are primarily unnoticed by most drivers, there are plenty of benefits that ensure operators can use the vehicle without application. 
  • Works behind the scenes
  • Ensures seamless & consistent use
  • Works through high engine temperature, altitude changes, and accessory loads. 
  • Fuel consumption reduction
  • Air-fuel ratio control
  • Exhaust emissions
  • Less maintenance

Signs of Electronic Throttle Control Failure

  • Decreased Fuel Mileage
  • Acceleration Issues
  • Flashing Indicator light
  • Sporadic Idling
If your electronic throttle controller shows signs of failure, the most likely issue is that it’s dirty. Thankfully, cleaning an electronic throttle body is pretty simple.


What does an electronic throttle control do?

An electronic throttle controller helps the engine to respond to inputs from the gas pedal more quickly. It recognizes the input from the gas pedal, tunes it, and sends it to the electronic throttle control system. It allows the throttle plate to open or close more quickly and means the car feels more responsive, and gives the driver greater control on the timing of acceleration or deceleration. Electronic throttle control systems also facilitate the integration of features such as cruise control, traction control, stability control, precrash systems, and others that require torque management.

Does a throttle controller increase speed? 

An electronic throttle control system boosts the response of many components when used in a vehicle. It has the potential to channel power to the accelerator due to it minimizing lag or hesitation. Meaning it makes the accelerator pedal control, respond, and accelerate faster. It is known for changing the way a driver operates the vehicle too.
