Nissan terrano 11 techometer not working
run a new line to the distributor.
It depends on what is wrong with it.The tachometer takes input from the revolutions of the engine, so can you identify if the connection in the engine is okay, or if the connection to the actual guage(tachometer) on the dash is okay.A test would be to get a working instrument panel,replace yours and see if the rev-counter(tachometer) works. If it does then it might be cheaper to replace the whole instrument panel. If it does not then the problem might be in the engine, you might want an auto-electrician to trace the cables etc.
you have to replace it
That means that the bearings of the mechanism have failed. It is not economically practical to repair the tach. You'll need to replace it.
Check the speed sensor
if you try to start it and it wont turn over it could be the timing belt. goodluck finding someone to fix it...
check your idle control valve located behind the engine
for the check engine light go to autozone and they will diagnose your engine for free as for the speedometer you will proobably have to replace the speed sensor
The tachometer on a 1991 Acura Integra is wired through the dash. To reach the wiring remove the dash console and pull out the tachometer. There the wiring can be worked on using a spark tester to find the bad wire and solder unit to replace the wire.
I don't have the answer to your question, but I have a similar problem and have tried a number of things. My Accord V6 is a 1996 and the same tachometer problems have been appearing and disappearing for about one year. Even the Honda dealership couldn't fix the problem. They have changed the plugs and rotors and the ignition kit. Unfortunately, whenever I try to bring the car in, it runs fine. Let me know if you get a fix.
