Yea there are several ecus over the car
The engine ecu does speed if you dont have abs
If you have abs, the abs ecu provides the info and passes it onto the body computer via canbus

no my car doesn't have the ABS, my speed sensor in on top of the gearbox which i did replace but didn't solve anything. I have checked battery and alternator and on volts side of things they are fine 12.8v with engine off and 14.1v with engine running, i have been told that amps matter as well but that it varies from car to car so need to find out what amps my battery is supposed to be for my car and check that.
Today i plan to go over the circuit as much as i can with a multimeter and try to see if i can find any brakes in wires etc.... thank you to everyone thats helped so far hopefully i will get there soon. any more help, info, tips etc... are all greatly appreciated
