Hi,

I have read some postings but I'm not sure what the problem is since I
haven't seen anybody with this particular behaviour.

After some radiator/timing belt job, the car's speedometer started
acting weird. It shows 0 MPH until I reach 40 - 50 MPH. When I reach
40-50 MPH, it goes to 65 MPH instantly (even though I'm not that fast)
When I slow down, needle goes down dead to 0 MPH again. It is automatic
transmission but there is NO shifting problem at all.

I mentioned to the mechanic who did the timing belt job, and he said it
must be the sensor since these models don't use a wired system.

Any opinions?

Thanks.

If it's a mechanical speedometer, check to see if it's catching. We had an
old speedometer in our Corvair do almost exactly the same thing.

speedometer) on my 93 prizm. how do i check to see if it is catching? i

I had a 92 Tercel that done this. It gets much worse in colder weather. Mine
would emit a horrendous buzzing noise at the critical point of 45mph. I
could hardly hear the radio. Apparently there is a set of gears or teeth
somewhere on the cable behind the instrument cluster that requires
lubrication, otherwise it will "catch" at about 45mph for some reason. The
shop I took the tercel to told me this and they lubricated the problem but
this was only a temporary fix. They had to take the instrument cluster out
to get to it I beleive, I'm not sure. The more permanent fix of course would
be to replace the part(s). Sorry I don't know that much about it, I'm only
going by what the guy told me.
