With balloon-ometer.
use an ometer
cable the ometer in its self nose not work
it's ether your meter cable is twisted or it's stripped out.
The vehicle speed sensor in the transmission may be bad.
the speed ometer cable is connected to transmission,unless its a4 wheel drive,then its connected to the transfer case.
abs sensors needs replacement I doubt this is true. I have same problem and abs works well on icey roads.
Yes it will send the wrong speed signals to the computer, you can change the gears to the speed ometer signal generator to correct that though. Check with a good auto tire shop , they should be able to tell you what you need to do.
using a high resistance-ometer ANSWER: Some commercial voltmeter have an input impedance of 11 mega ohms So instead of measuring across the resistance you may put the meter in series that will give you a voltage drop due to current that can be calculated to find the other resistance
on my 85 nissan,the dial indicator is cracked,i was told i would have to buy a whole new speed ometer,so i use my tacometer to tell me my speed.,no speeding ticket so far,upp i need to knock on wood.
fill up your tank, , keep track of how many gallons it took to fill up, re-set you trip ometer, then drive your car until the gas light come on, take total miles traveled and divide the by the number of gallons you put in your car and that's your MPG EX 375 miles on 13.5 gallons =27.7 MPG
I have already had to do this... There is a cable that runs from inside(underneath) the speedometer to the front wheel. Make sure both ends are connected properly, also check to see if the cable within the tube is not broken on the ends and reaches both ports. if it does not it will read your speed sporadically or not at all, which was my problem. Its an easy fix and not an expensive part to buy. Only difficulty I had was feeding the new cable through, so be careful.
