Speedo not working

The speedo and odometer both use a signal from the speed sensor in the transmission. If both have stopped working, the problem could be the sensor.
If the odometer still works, the problem is inside the speedo head.

In 2.8 Pajero the speedo receive electronic signal from the VSS sensor, but if the speedo for any reason stop working, O/D will stop work because the Trans ECU needs signal from the speedometer electronics to made the gear change into O/D

Car don't usually have fuse's on speedos, it stops people "clocking" cars. If your speedo is not working then is could be either the speedo drive or the speedo itself.

no, because the tach uses a different sensor than the speedo. You probably have a connector issue. Is the clock on the same panel? See if you can reach behind and push on the connector. If you want wiring diagram, let me know and I'll see if I can find it.

then its possible they also have a speed sensor

Speed sensor has failed.

It is basically a magnet sensor that reads the RPMs of the tranny.

It is screwed into the side of the transmission.

Do you have an aftermarket alarm installed, or remote start?
Sometimes those wires can be damaged if not installed properly.

It is $33.00 at autozone.
Part #SU1090

:D

the speed sensor is located in the transmission near the prop shaft. has nothing to do with the clock. you may want to check the fuses first

If you have a speedo convertor/delimiter chip fitted (UK market mph) this is often the cause.

it's most likely the cluster if one function works and the other doesn't. And, you likely have an electronic vehicle speed sensor that sends a signal to your analog cluster that then dispays your speed and odometer.

You will need to replace the speedo head or have it repaired by a factory speedo service center, your Mitsubishi dealer can provide you with a name and phone number.
