Hello Sir;

Car is from 1998; so, so
Far my best option is the phonic wheel.

I think it has 50 teeth, so every revolution of the wheel, i will have 50 pulses.

Knowing that and the tyre circumference I should be able to easily determine the pulses per Km,

Every Km the wheel does 490 revolutions, so 490X50= 24500 Pulses Per Km; correct me if i’m wrong.

Thanks again
