hey guys
i just bought a 1994 pathfinder 4x4 with 180k on it. pretty solid truck. one of the things thats broken on it is the tach.
when the cars off, its at 0 rpm like it should, and when the engines running, the tach stays at about 3000 rpm and barely moves at all when you rev it.
Id like to get it working, but i dont even know where to start... anyone know?
also, it has an electronically controlled transmission... so does this mean that if i fix the tach it will shift better? it shifts decent as is, but i feel like it could be shifting better...
it already has an aftermarket transmission cooler attached to the AC core... not a very big one though, but atleast its not that.
tachometer not working right!

Hey I have a 95 Pathfinder, they have the same gauges.
When I bought mine tach didn't work at all, bounced all over the place, what ever it wanted to do..
It's either:
Get used to it,
or replace the tachometer unit.
I took a chance since I really didn't know either, but I got a tach unit from a junkyard. Usually they only sell the gauge cluster as a whole but I got lucky because someone stole the speedometer out of the cluster, gave it to me for $5. Anyway, to replace the tach you have to literally take apart the whole bottom driver side dash to get to the cluster. Then it's just a take out, replace..
I'm not sure if it was worth it, but I just have to have a tach.. It took about 40 minutes from start to finish, everything back in place. There is a diagram somewhere online, but I just took the logical screws out until I got to the cluster. Be careful though.

i read somwhere that the electronically controlled transmission takes RPM into account when it shifts.
there must be an RPM sensor somewhere... if theres a problem with that sensor, would it screw up the transmissions shift pattern? anyone aver replace this sensor before?
on the other hand, if its just the cluster, that shouldnt affect the shifting...

tachometer
In your case, it is certain that the tachometer is not working. I got a cheap tachometer just last month and I find it satisfactory and reasonable for the price. Just in case you needed one, it's worth it a try.
Tach bounce
This is a known issue with this vintage PF. The only cure I have found is to replace the head unit (in the dash), which is a PITA.
Failing that, you can install an aftermarket tach.

Sounds familiar... haha. I used to just give it a good !wack! on the dash, and it would stabilize, But now its fried i am afraid. I may go hit up a "pick and pull" for a new one. If i get stuck i may ask you a question.95TerranoWA wrote:Hey I have a 95 Pathfinder, they have the same gauges.

Just picked up a 1995 Pathfinder and its been a great little rig. Had a few minor issues but Im stumped on one of them.
The cruise does not work but all of the lights light up and all seems to be in order. However my Tach is messed up as well. It pegs out as soon as I start the engine. Could this be sending a message to the cruise to shut down?
Was in a car this weekend that got close to red line and shut off the cruise by design. Made me think that maybe my cruise issue is related to the tach issue.
Any ideas?

Where is this resistor located on the truck and do you remember the part number and where you got it from? Mine is doing the same thing, sometimes it will work just fine, sometimes it wont work at all and other times it will just go all over the place.95XE_PATHFINDER wrote:No don't replace the TACH are you nuts?! there is a resistor on the pathys there like 16$ thats what my problem was I bought the resister and it worked like a charm
