Accelerator control......

[Doug627586]

I am re-posting my earlier question, as I only got 1 response. Although their reply was useful, I need a wider response from as many car users as possible, so if you know if this system applies to your car, let me know the make and model.
Many thanks.
I am trying to find out how many cars use an electrical control for the accellerator (or throttle) instead of a cable control.
I understand the bits involved are a potentiometer (variable resistor) on the accellerator pedal, which then sends an electrical signal to a similar device at the fuel supply end, to adjust the amount of fuel issued to the cylinders to control the vehicle speed.
I believe it is only something used on more modern vehicles, but would be interested to know what percentage of newer vehicles use this method.

I imagine most modern cars use a fly-by-wire throttle in order to manage exhaust emissions and modern driver aids. The accelerator position sensor does not go to the throttle, it goes to the engine management unit. It is the emu that decides how much to open the throttle and it makes the decision based on various inputs, not just the accelerator position. So, what are the other inputs? Engine temperature, engine revs, sensors in the air intake and sensors in the exhaust. On my car the EMU also regulates the throttle to provide traction control and stability control.

But, to answer your question, the Mazda RX8 does indeed have a fly-by-wire throttle.

My Transit Connect has one....my neighbour has a 3 litre Vectra and he's got one...my son makes bits for Lewis Hamiltons car, and he assures me he's got one..

There you go ... they are as common as old muck.

Fiesta have had them since 02 i think. They bring up EAC light when there is a fault and the pedals clip on to connectors rather than cables.

My previous 1999 Focus Diesel and present 2005 Focus Diesel both have electrical throttle control.The previous being a 1.8 TDI and the present a1.6 TDCI
