Where is the tach sensor 1994 pontiac trans sport 3100

Its definitly a bad reading, you would know if your vehicle is overheating, you can usually smell it right away.I would say its your temperature gauge sending unit is defective, check the wires to see if they are well connected or broken. ask a backyard mechanic for assistance.

It sounds as though your Crankshaft Position Sensor has gone out. They are pretty easy to change. You will have to remove your harmonic balancer/crank pully to get to it, as it is on the inside of the pully. Also, if you have a 3.1 engine, you have a second Crankshaft Position Sensor on the side of the engine closest to your firewall. (it is below the number 1 and 3 spark plug). It could be that one or the one behind the balancer. I would suggest replacing both of them at the same time. As for removeing the harmonic balancer, you should use a puller to do so. When reinstalling it, do not use a hammer or anything to tap it back on, as this can damage the balance and also the crankshaft. You should use a harmonic balancer installer to put it back on. Both the puller and installer can be borrowed from Autozone (with a deposit that will be returned once you return the tools).

I have the same problem.. i installed a toggle switch for the fuse so at least I can reset it while driving.. its still a pain so Im thinking my next step will be to drill a hole through the plastic and put in a small metal post to stop the tach from going past 7

has anyone taken theirs into a shop?
