Greetings all, I've got a 1993 Olds that recently started
intermittantly showing the Service Engine Soon light, but only after it
warms up.

I pulled the code and it's a 56, transmission input speed sensor
(TISS).

The car has around 164k miles.

I'm thinking either the sensor is bad, or most likely it's a problem
with the wire since it's coming on only after warming up. I don't know,
I guess it could be both.

Anyway...my question is, would it hurt to just leave it alone and run
it as is, or should I get this fixed? It doesn't seem to affect how the
car runs.

Thanks,

Phil

Doubt it is the wire. Wires work in most any temperature in North America,
South America, Europe and Asia. I think the polarity is reversed in
Australia.

If this is a false code not relevant to the input shaft speed, yes you can
drtive it.
