General consensus is that the actual reading is less important than it has continuity and is not shorted to the housing.
If you have a meter that will measure Hertz at 40 to 45 mph it should produce 60 hertz just like a North American wall outlet in the house.
on the transmission
A low oil pressure reading when idling for a 1986 Fiero is normal. As long as the oil pressure goes back to normal when the car is being driven, there should be no problem. If it is not, then the oil pressure sensor or the oil sending unit should be looked at.
you're not moving?
It depends on what Fiero SE you own. There are two types. The earlier SE models, '84-'86, used a 85 mph speedometer for the four cylinder engine. It would not be until the '87 V6 model that the SE cars received the 120 mph "GT", as it's called, speedometer assembly. If you already have a 120 mph speedometer in your Fiero SE, it will work just fine. If it's the 85 mph speedometer, it will not, and would read incorrectly until you perform the necessary modifications to make it act like a 120 mph speedometer should.
Yes. The THM125C has a governor. The governor is just below the speedometer sensor. 1986 Pontiac fiero service manual section 125C page 22.
Fiero does not use a speedo cable There is an electronic sensor mounted on top of the transmission that both the engine computer and the speedo in the dash read to get the speed.

this should help you out! Brian
You will see it screwed right in there in the top of the tranny with 2 wires coming off. It's a pretty large sensor so it's fairly obvious. Just run into any AdvanceAuto Parts store and check out the Haynes manual for a Fiero. It's in there. You should a manual already if you own a Fiero or you should get one! ;-)

where is the coolant temperature sensor locate
I'm not sure about the speedometer, but if the tach is not working a good bet would be the tach filter. With age, a wire often breaks off on these. Look in one of the service manuals to find location. The speedometer may have a similar sensor, but I'm not certain. Thanks! I will check out the book ASAP. Appreciate your answering.
