Computer will only detect problem as of no signal or signal out of range, but is will not say whick is the failed component. number of test has to be performed to determine what is causing that signal to not be present or wrong.
it may be sensor/sensor wiring/ combe meter/ ABS sensors/ ABS unit or engine computer. if you give me that code # XXXXX will be able to get more specific information?
What is the standard dealer cost (parts and labor) to replace the speed sensor? What is the standard dealer cost (parts and labor) to replace the combo meter?
Standart replace labour is 0.7 hors speed sensor cost is around $120 but it may be a bit different from state to state.
