Hiya can anyone tell me how the traction control works on a Calibra V6 auto? im dubfounded as to whether it works through the brakes, gearbox or the spark from the engine (to cut the power) Any help would be much appreciated! :) :beer: :beer:

I have a Cav V6 auto so its all the same. Open up the bonnet and look at the throttle body. You will see a small sandwich plate between the throttle body and the start of the inlet manifold. In this plate is a second throttle butterfly, like your first throttle butterfly that YOU control, this secondary one is controlled by a motor attached to the traction control ECU.

So when the ECU detects wheelspin the secondary throttle cuts power progressivily (but quickly) until the wheels regain traction.

I didn't know you could wheel spin an auto? I'm guessing only when the road is wet, that this is possible?

Depending how much power the auto is running. The old jag v12's are helish to drive be it wet or dry.

The Cav system uses a motorised throttle plate controlled by the TC ECU, and Fuel/ignition cutoff controlled by the engine ECU.
