Tachometer stopped working. Is it some sensor that I can fix myself?


Year/make/model?

If it has an ignition control module there will be a "tach out" wire it is usually white in color, you can check that wire for tach signal. If no signal replace Ignition control module. If it has proper signal it is likely a bad gauge in the instrument cluster.

Tachometer not working on my 95 Toyota pickup 4x4 jumping up and down


bad tach, seems .
bad tach, or bad wires to it or power to it bad.
i dont know what engine option you have
but most use the ignitor signal to do this.
later about 1996 the ECU uses CKP sensor to run the tach directly
in that case bad tach, bad wires to tach or bad power feed to it.
it only has 3 wires.
power
ground
sig
one is bad, or its bad.

I have an 89camaro irocz 28 with 5.0, with a rebuilt tranny about 3 yes ago. While driving on overdrive at about 40-50 mph it will shift into od geer then back to 3rd then od again what could be causing...


Yes it can be what it is doing is called hunting, As for your RPM tach it has nothing to do with it, Now your transmission is a 4L60 and YES it does need a tach signal or the RPM signal it doesnt matter if your Tach gauge doest work but it need the tach signal for the transmission to work. And NO there is NO VSS it needs TACH. or it will hunt for a shift that is why its doing this.Youll need to restor the TACH to the transmission so it can shift properly, Now youll either have a 4pin connection,1 wire or youll have a 4 pin 2 wire connection or youll have a 4 pin 3 wire connection This transmission need tach signal so bear with me i am going to some how draw it pretend your looking at the switch. connection

I need to know where to wire the green wire to read RPM's for an aftermarket tachometer install on a 1999 chevy s10 with a 2.2l 4cyl.


It is usually to the positive side of the coil - also depends on what type of distributor cap you have, if there is a 3-4 wire plug that goes to the cap, one of them should be marked TACH
