E12: Vehicle Speed Sensor?

[proguru]

Hi.

I have an engine fault light lit and the fault code P0500 that translates to vehicle speed sensor.

I understood the sensor is the thing on top of the transmission, but where can I order the spare part, I could not find one on eBay.

What is this sensor? The speedometer works fine. In most cars the speed is measured using abs sensors on wheels.

Hi proguru.

The p0500 error code does relate to the speed sensor that is mounted to the top of the gearbox. It can be failing (but not enough to stop the speedometer from reading) or it could be sending an incorrect signal to the ECU whilst the car is not moving.

This can be caused by a faulty sensor unit, corroded / dirty connection or damaged wiring to the sensor.

Best bet would be to check the wiring and connections first to before splashing out on the sensor.

The speed sensors on the ABS are different in that they monitor rotational speed of the wheels and trigger the ABS system when the wheels rotation slows too quickly. They don't send a signal to the speedometer at all (that I am aware of).

Let us know how you get on.

All the best.

Hi.

I unplugged the connector and spayed the contacts with CRC 5-56. No fault light since, yet...
