SOURCE: 2002 ford focus 1.4l ,73000mls,speedometer problem.

it is the vss (vehicle speed sensor). i had the same problem, cost £35 for sensor and clip. its behind the gearbox. very awkward job but can be done yourself. the hardest part is getting the pin out, you need a very good pair of molegrips and a lot of patience.

SOURCE: '99 Beetle cruise control surge and speedometer

I would take a blind guess and sat the speedo sensor has an issue. 99' beetle should have an 01M auto, and the speed sensor is also the dipstick for the final differental drive. search around this area of the trans for the cable and snoop around. loose at the trans ? bad connection somewhere??

SOURCE: speedometer drops to zero while moving and then

The Vehicle Speed Sensor located on the Transmission is malfunctioning or the connection is malfunctioning.
It is very easily removed and replaced.
The Vehicle Speed Sensor sends vital information for the Transmission to properly Shift. Because yours is malfunctioning, this lack of information is causing shifting problems.
I do not know if you have a Mechanical or Electrical (Gauges or Digital) Instrument Display. I also do not know if you have a 17 or 19 bolt transmission pan, nor what type of transmission you have (AX4N or AX4S) Nor if you have a Speedometer Cable (Mechanical Instrument will have Gauges=Cable).
The best thing to do is to check the connections of the Vehicle Speed Sensor. Unplug and check both sides of the connection for corrosion/oxidation. You can also take this sensor out of the transmission and clean the interior end; reinstall and recheck operation.
If this does not fix the problem, then remove and replace this snsor.
Take the Sensor with you to the auto parts store to compare the part you receive. You should know what tansmission you have and the number of bolts on the transmission pan, and whether you have an Electronic (Digital) Instrument Panel or Mechanical (Gauges) Instrument Panel on your dash.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Honda accord speedometer drop to zero


You may have a problem with your IPC (Instrument Panel Cluster) which often can be exchanged for a serviced and warrantied replacement unit.

First thing I would try...disconnect the battery for 10 minutes which will allow the on board computers to re-start.

If this doesn't help... I would retrieve any stored codes the on-board computer has logged which may provide a starting point to diagnose your trouble.

Replacing speedometer cable


I do not believe there is a speedometer cable in a 1992 Olds. I think that you have a speed sensor that transmits to the speedometer via two wires. The speed sensor is mounted near the drive shaft where two magnets transmit rotation speed to the sensor.
