Possible Solutions to Problems On Electric Vehicle Speedometer

Nov 12,2021

A working electric vehicle speedometer provides the driver with valuable information about the car’s speed. Modern speedometers use a magnet on the rotating shaft and a magnetic sensor to calculate the car’s speed. Older cars use an electric current on the rotating shaft and, by measuring the magnetic force produced, one can get a speed reading. However problem with a cable replacement in older speedometers and speed sensors in newer ones can cause this tool to not function properly. Is your speedometer not working? Read on for information on how to fix this problem.

Finding a cable replacement

  1. Remove the engine cover and doghouse from the car in order to remove the cable.
  2. Remove the bolt from the dashboard and access the old cable.
  3. Remove the nut on rotating shaft and pull the cable through the passage.
  4. Remove the clamp from the transmission and engine compartment.
  5. Tighten the nut on the rotating shaft and fix the square end of the new cable in the adapter.
  6. Using the passage we used to remove the old cable, pass the new one through and tighten the bolt at the rear end of the cable.
  7. Put the clamps and engine cover back on you removed in the first step of the process.

Speed sensor replacement: front wheel drive vehicles

You will find the speed sensor behind the engine and above the trans-axle.

  1. Remove the connecting hose, air cleaner, and electrical connector.
  2. With a 10 mm socket, take out bolts keeping the speed sensor init’s place.
  3. Unscrew the sensor to take it out.
  4. Replace the sensor in place and tighten the bolts we previously removed around it.
  5. Reattach the hose, air cleaner, and the electrical connector to the sensor.

Speed sensor replacement: rear-wheel drive vehicles

You will find the speed sensor on the driver’s side behind the transmission.

  1. Raise the vehicle upon the driver's side and keep it there using a car jack.
  2. Disconnect electrical connectors present on the sensor and take out bolts keeping the sensor in place, using a socket.
  3. Take out the sensor carefully and fix a new one in its place.
  4. Attach the electrical connector to it and tighten it.
