I have a 95 maxima GLE manual and my speedo is 15 off. If goes back to zero when I turn it off, but as soon as I turn it back on it jumps back up. I have no idea how to fix it? When I brought it it had 18's on it, I thought that might be doing it, so I put stock 15's back on and it is still doing it. Any suggestions would be appreciated

 

So when you turn the key on, it goes straight to 15 mph? Has it always been like this, or did it just start happening?

Are there aftermarket gauge faces in your cluster? Chances are, the needle wasn't correctly reinstalled when reassembled.

 

This is hella confusing. Is this electrical related or....nvrmnd

 

In no way trying to thread jack, but I have the same problem with my tach. Recently removed it from the cluster to do LEDs, and upon reinstall as soon as I turn the key to the ON position, the tach jumps to ~5-700 RPM No needles were removed.

 

No, as weird as it is, everything is stock. I bought the car off someone and he mentioned that at tos but I figured just size of tires. But it goes to zero when I turn the car off and jumps right back up again. It's easy to get used to lol, but I'd like to actually hit 110, not 95. I'm thinking possibly the speed sensor. Thinking will take it off and have Autozone take a look. Any other suggestions?

 

Nope, all gauges and everything is stock. Puzzles the he'll outta me, but it is a constant 15 and doesn't fluctuate.

 

Auto parts stores don't have any real diagnostic ability, especially with components off the car. Are you throwing any codes for the VSS?

Have you checked the screws in the back of the cluster, see if they've loosened up at all?

I'd probably start off with a scan tool (or at least a code reader that can do live data) to see what the ECU is seeing for a speed input. This will narrow the possibilities down quite a bit.

 

Well Autozone said that they could do a check on it and I'm not throwin any codes for anything. I can see if I can find a live scanner. The bolts don't matter but I'll check that too. I really believe it's electrical, but I have no idea where to begin. Since it's a 95 it's an obd1 so I don't believe it saves previous codes.

 

The bolts DO matter as some provide ground...

And its OBDII. Has been discussed several times. All 4th gen maxis are OBDII

 

The machine screws dont just provide ground, they are the contact point for the gauges to the circuitry.

Sounds to me like its getting a constant voltage. Not sure what the ecm or cluster to with the signal from the hall effect sensor, but if it is converted to DC, something isn't right.

 

well ****, you learn something new everyday then. I coulda swore it was a OBDI. so then pull the cluster and check bolts is on checklist as well

 

Wonder if the ODO was rolled prior to sale?

I'm not sure either, i was told but o riley's that it is most likely my speedometer, but i didnt understand how it would work perfect but be off. So then it may be a contact point on the back of the cluster or something. More things to check lol im going to figure this thing out as soon as i get out of work. I would say it was related to the 3 15's i currently have in my trunk, but it was like this when i bought it.

 

I would go to a junkyard and pick up another speedo, or get one off ebay. I've seen them for $30 on there. It would mess up the mileage on the car reports and title, but it's not that hard to change out, and it might be an easy fix.

Other than that, It might be a short from another live wire between the VSS and the speedo. If I'm not mistaken, the speedo is based off an electrical current coming from the VSS, and if the wire was touching another live wire with low voltage, it might always make it sit at the 15 mph.

 

makes sense ill take a look and i can test the wires with a volt meter, shouldn't be too hard. so there is no way to adjust miles on the speedo if i get a diff one?

 

I'm parting out my car, still got my cluster, lemme know if you're interested.
Dr J

 

how many miles your cluster reading?

 

I think 223k. Don't think it matters, as stated in previous post, you're gonna hafta re-register w/ DMV anyways, especially if you guys have emissions testing. Do you?

Dr J

 

nope no emissions for me my exhaust has like 10 holes in it lol it wouldnt pass anywhere mine only has 123,XXX on it lol it sat for about 7 years until 2008 when some guy bought it then i bought it off him lol

 

Here is a vid of my speedo im gonna do an ecu scan on it this weekend( as soon as i find somewhere that will do live scanning too)

I don't know...would their be any way to find out?

 

Ok...now I understand. It would almost seem like its connected to the fuel gauge like how some cars operate, but ours don't do that, so this is a tough one.

 

yeah thats what i was thinking, it has to be electrical so im gonna check with a live scan from my OBD and see if i cant catch my ecu mis-reading or some BS. I acnt figure it out lol. prolly gonna check my speed sensor while im there.

 

Just curious, how's your cruise control?
Dr J

 

Well, in a huuuuge stretch, You could leave a deposit with me, I'll ship my cluster out to you to try out. If you keep the cluster, I keep your deposit. If you ship my cluster back to me, You'll get your deposit back, less fees.

Dr J

 

cruise works perfect i use it 12 miles to and 12 miles from work every day never an issue and as far as the cluster, if i cant figure it out i will more then likely take you up on that

 

See my car has been sitting for nearly 2 hours now and the needle is fully at 0 now

Here is my OBDII reading for the maxima. I found out that mine isn't fully OBDII compliant but here is the vid

Bump

 

Don't worry about those sensor thing at the beginning, not related and no biggie.
P1400 and P0433, neither related to speed sensor or the speedometer, but worth looking into.
This's really weird. Let's google some other stuff. brb

Dr J

 

Back. Well, good and bad news. Good news, there's a TSB about your codes. Bad news, you gotta do just 1 more step for confirmation of diagnosis. PM me your email address, I'll send some pdf's to you. I think it's best you run a continuity check for the speedometer. I don't have the FSM so can't help you there. Ask someone else for those.

Dr J

 

Dr J

 

And that should take about 15 mins to pull out and about 30 mins to put back in lol...i also have to check my speedometer this weekend as well. I notice when im driving over bumpy roads(backroads in iowa blow), my cluster rattles and if i put my hand on it then it then it stops? curious. how long you think it will take to pull my cluster and check screw continuity and grounding?

 

PM'd

 

I just pulled mine out this weekend, literally took a few minutes. Get yourself a philips screwdriver. Under the steering wheel, there are 4 or 5 screws. Then pop the plastic top off the steering column (you can leave the bottom hanging). You'll need to put the steering column in the lowest position.

Look under the cluster shroud, you'll find 2 more screws. Pull the shroud out. Unhook electrical harnesses to any switches still attached to the shroud. Pulling the lower portion of the shroud out was scary, I thought I was gonna break it. Just take your time.

Then remove the 2 (or was it 4?) 10mm bolts holding the cluster in place. When you take the cluster out, be careful of the delicate ribbon wiring attached to the back of the cluster.

On the back of the cluster are a bunch of little screws. I loosened mine, then tightened them again. Also clean the ribbon contact surfaces with dielectric cleaner.

I got your email, but I think I deleted the tsb pdf. Lemme rummage through my recycle bin. BRB.

Dr J

 

dude i have crawled the web nothing on home depot, walmart, lowes, menards, autozone, advance on dielectric cleaner...WTF where do i find it...is it like the holy grail of cleaners...im lucky to find a can after every lunar eclipse type thing lol

 

You need to replace you vss sensor...my 95 gxe was doin the same thing...needle was jumping around frequently too though, replaced the vss 30 bucks new at parts store...and 15 minutes of time....and BAM speedo worked great after that....too bad i dont even drive the car anymore LOL

 

Let us know what fixed it. Mine had no speedo function when I bought it, but luckily, it was just disconnected from the VSS. Yours wouldn't be that tho since it works, just not as intended. Good luck!

 

lol im hoping it is just a loose screw in my cluster, but wont find out till this weekend. Im nervous to screw with it cause i dont want it off anymore then it is already lol so im gonna multimeter test my VSS first then check cluster if that doesnt fix it. I still cant find dielectric cleaner i even called a speciality store since it is mostly used for like cleaning electric points and stuff and they thought i was retarded or something lol

 

i shall and hopefully post vid as well
