Hello all,
I have a: (3000GT TT UK car)
It has the following issue:
The speedo needle doesn’t really move, sometimes it flickers.
The odometer (trip) works, but I did a run early and I cculatrd it should have been about a mile but it recorded 0.6miles. So its working just under a bit.
Do both run from the sake source on the car? I.e if the speedo doesn’t work will the odo not work either?
I habe read about the speedo gear, if this wasn’t operating correctly would this impact the odo?
You first need to determine whether you have a mechanical cable fed speedo or a pulse generated speedo. Most cars are pulse which is generated buy a sensor mounted on the gearbox. This is driven by a gear which is inside the gearbox and can wear. This means that the gear will slip and fail to turn the pulse generator. Fewer or no pulse count will make the speedo erratic or show nothing. It is also common for the pulse generator to have dirty contacts which prevent clean pulses going to the speedo. Finally, the speedo itself is starting to become a problem but this can be repaired.
Thats great thanks. Its a 6 speed twin so I presume pulse on these. Can this gear be bought separately i dud some reading with people pulling the sensor out and replacing it.
Mitsubishi should be your first point of call but please don’t start throwing money at random parts. Fault finding should be easy. Which country are you in ?
Yes, it could be the speedo but it is easier to start at the other end.
I had similar issues with my speedo no long ago, some times it was working or the needle was going up and down or all the way to the end of the dial like crazy and the odometer was going too fast adding lots of miles. Joe is right about the possible causes , in my case it was the sensor top not the gear !
Hi yes you can you need to remove a few hoses above it and maybe get under the car but the whole unit can be removed.
Mine has been fixed now, I had the the speedo gear ring (new from mitsi) and also the unit was swapped for a known working one and my speedo works perfectly now.
Mine was done by David Healey in Stoke on trent, good chap knows his was around these cars.
Hi Joe. I’ve learned a lot with my 94 base model but the Speedo gear more than likely is the mechanical one I am assuming. The more I learn with this base model I feel will help me when I finally get a turbo model. The only thing on my car so far that needs attention is this and the srs light.
