My Raum’s speedometer is not working anymore. Why?

Paul, What could have spoilt my Toyota Raum 2002’s speedometer? It stopped suddenly. Can it be rectified? Julius A

Hello Julius, a faulty speedometer can be a big inconvenience, especially when you have to drive on the highway and you can’t keep a track of how fast you are driving or how far you have driven.
On your Toyota Raum a speedometer may fail due to a breakdown of the VSS Vehicle Speed sensor, VSS circuit or the instrument cluster which houses the speedometer.

Many modern car speedometers draw their speed information from a Vehicle Speed Sensor which is attached to the transmission. The same speed sensor helps the operation of the cruise control and will cause a diagnostic fault code or check engine light if it fails. A computer diagnostic reading will quickly confirm if its the culprit.

A break down or interruption of the circuit between the VSS and the engine computer will also lead to failure of your car’s speedometer.

If the two are okay then a good technician needs to investigate the condition of the speedometer in the instrument cluster.

Sometimes a faulty instrument cluster will lead to failure of the speedometer.
