Alphard 3lit auto gearbox speed sensor

[Guest]

Hi all. Had an issue today with the van. First the engine management light came on the a while later the speedo stopped working. Vehicle is driving fine.

Took it to a garage who plugged in into the Diagnostic machine. They said it is the gearbox speed sensor.

My questions are:

What is the best make after market sensor to buy, & where from ?

Going to start with Toyota but I guess they are going to be expensive.

The other thing I have just thought of, could it be the thing that converts to miles ?

If anybody knows the part number for the sensor, that would be much appreciated.

Many thanks in advance to all you knowledgeably people.

Hello Kevin can you pm me your reg no. And I will get the part no. For you regarding  the part that converts the miles is called a ckun09 chip this sits behind the dash there is a possibility it could be that at fault . The speed sensor there is 2 fitted to the gear box as I had mine replaced 18 months ago similar fault to yours .
