Hey all! I'm looking for any ideas on my odometer problem. The speedometer works fine but the odometer is not working now. The car was purchased with an engine with blown head gaskets. I wasn't able to drive it to see if it worked until I fixed the engine. So I swapped out the engine with another but used the same transmission. What happened when I drove it was the ODOMETER INCREASED MILEAGE 10 times or more than the actual mileage driven. So it basically went from 80,000 miles to 300,000 miles in about 5000 miles. You get the point. So now the odometer isn't working at all.

I didn't want to replace anything until I'm sure what caused it. But of course in need to get it inspected and my garage doesn't want to pass it without it working.

Thanks

It's all internal to the cluster.  The drive in the trans is just an electrical signal to the dash.

I'd grab a used dash from a yard and put it in.

Ok but the dash odometer is an analog unit. Not a digital readout. Is it still an electrical signal to it?

Yes, an electrical motor drives it.

Thanks Imdew I'll see if I can locate one

that's hysterical..... sorry it's a pain....but that's nuts how it would rack up miles like that.

 

The clusters are super easy to swap in a few minutes. a few screws for plastic trim and they have like 4 screws to remove the cluster. I feel like some you only need a Phillips head screwdriver, no sockets at all.

 

The car runs and drives without the cluster so if something happens you'll still have a perfectly drivable car. It's just weird driving without seeing anything and a little risky if you're not 100% confident in the cooking system/temperature.

 

Is it possible for the sensor to cause this? I would guess cluster too but just checking.

I would bet the cluster motor uses a pwm to control the odo speed. If that failed, cluster would go ludicrous speed or nothing at all. Likely end up burnt out.
