Odometer stuck on zero.

[James Brown]

Hi all,

Looking for advice on which part  needs attention/ replacing.

Engine warning light is on & odometer is not moving from zero. Then whilst driving, revs will drop then surge for split second & warning light goes off & odometer will register for a short period then back to zero with warning light.

Any ideas please.

Hello James have you had the engine codes read by diagnostic this is the first thing that needs to be done .

Hi lee,

Taking to garage, will advise when done.

Initially thought that someone would recognise this fault.

It could be a number of things my best guess would be speed sensor on gear box there is 2 fitted

Hi again Lee,

Looks like you may be right about the speed censors.

The auto electrician needs a wiring diagram as he says the 2 wires do not go straight to the speedo head.

Is one available on the Forum?

Also, part numbers for the 2 speed censors & recommended supplier, Toyota are quoting £168 + vat each.

Thanks in advance for any help.

hello james i have sent you a private message

Many thanks for that advice.

Does the speed sensor wiring go direct to speedo / odometer head or other ?
