I upgraded to 20 inch rims with 20mm spacers and my bas esp light came on and I am lacking power, is there a way to recalibrate the sensors or how can I put this vehicle in dyno mode? I am running 265/50/20 and stock is 285/50/18 the vehicle had 265/60/18 on it so when I did the plus size the coputer said 265/50/20 would work. What are the odds that I have a sensor failure? Brake lights work so I dont think it is the brake switch. Thanks

What do the sensors read? The rim rotation or the rotor, How do they work?

ohh my combined offset is 55mm and within tolerance according to Les Swab
