Okay so a few weeks ago me speedo went out. At first i thought it just might be the cluster (like last time), but this is a much newer JDM cluster. I hunted through the junk yard yesterday and found 1 VSS. When i went to install today i found out that it was one of the wires to the VSS that was cut...

So i repaired the wire and **TAAHHH DAAAHHH** speedo works again.

Cause: worn tranny mounts and frequent scrapin probably caused the tranny to move a lot and some how pinched the wire against something.

Everyone with dead speedo's, worn tranny mounts, and low chassis should go check this right now!!!! Good Luck.

speedos are for quitters
if ur speedo isnt pegged, u arent going fast enough.

420sx · 03-14-2007, 06:48 PM

you dont need it. all u need is a tach haha

civilized_drifter · 03-14-2007, 09:09 PM

no speedos are the way to go....but if i was goin fast enugh it would move backwards

DriftSpecial180 · 03-14-2007, 10:19 PM

Thats funny, no speedo=speed cut. it wouldn't be possible for me to go fast without it... : (

No speed sensor (in the trans) = no speed cut.

d*star180 · 03-14-2007, 11:20 PM

not true.
I was missing mine.
Was getting even worse speed cuts. Couldnt give it hardly any throttle.

DriftSpecial180 · 03-15-2007, 12:12 AM

Yeah, i don't know how you wouldn't get speed cut. The ECU doesn't know how fast the car is traveling and there is a 115 mph speed cut. so wouldn't it just be guessing when to cut? (right?)

initial_drifter · 03-15-2007, 12:24 AM

if you really want to get rid of the speed cut just get an auto ecu

5t341tH · 03-15-2007, 12:25 AM

theres a speed cutt?? i had an auto s13 and i took it past 115 on the speedo. like 2 cm below the 115 mark. now its a 5spd but i havent tried maxing out since

Akiros · 03-15-2007, 12:27 AM

no ka 240sx auto ecu has a speed cut

initial_drifter · 03-15-2007, 12:39 AM

You sure? Cuz i've driven with the speedometer's needle stop and my rpm's were only around 4.5-5k ish and I was still going.

btw, it's got a manual tranny if that makes a difference

DriftSpecial180 · 03-15-2007, 12:51 AM

Well i don't know the exact speed, but its somewhere around there. When my speedo is dead sometimes it cuts when i'm going like 60 mph, depends on what gear i'm in.

A Spec Products · 03-15-2007, 02:22 AM

my speedo goes in and out these days

dont matter

gas gauge doesnt work either

dont need the temp gauge

theoretically i dont need the dash cluster at all

GSXRJJordan · 03-15-2007, 02:48 AM

I remember the first time I saw a working tach and HUD on a S13... I flipped out lol, thought something was wrong with his dash. My speedo's never worked, and I'm pretty sure I plugged in the VSS and associated wiring myself on my current SR, and I did wire the dash harness myself. Oh well, no speed cut here, and the rest of the cluster works great ~

420sx · 03-15-2007, 05:59 PM

only gauges a man needs : a tach, water temp, oil press.
bye.

slideways2004 · 03-15-2007, 06:19 PM

my speedo goes to 20 mph and stops. all i look at is rpm.

p.s. on my old koop, my hud, tach, gas gauge worked. don't know about speedo, never drove it

Full-Lock · 03-15-2007, 07:25 PM

tach doesnt work
when it says i have half tank, im out of gas
speedo reads k/m and it is still off target

benefitx · 03-16-2007, 09:51 PM

VSS? speed sensor?? what is a VSS

benefitx · 03-16-2007, 09:57 PM

my speedometer also does not work , it works backwards.

johngriff · 03-16-2007, 10:20 PM

Speed Cut =
Speed Signal into ECU
4th Gear Sensor vs RPM
5th Gear Sensor vs RPM

Subtract = No more Speed Cut.

Dude, this shit is easy to wire up/fix. Dont be LAZY. I had my speedo not working for like 2 months, every girl who got in my car talked shit about it.(some s14 owners talk more shit than others..) F that.

sr20det4mys13 · 03-17-2007, 12:06 AM

iono i love my speedo to go all the way to the first digit on my milage.. bad ass.. latah

ROTTEN EGG · 03-18-2007, 04:44 AM

my chiltons got owned and the online links for a sohc KA are all dead. anyone mind sending me a FSM or the page for the VSS location for an auto?

johngriff · 03-19-2007, 04:01 AM

Crawl under the car, the Speed Sensor (VSS) is at the tail end of the transmission, it looks like a cylinder 3/4"roundx1 1/2" tall, with a wire lead hanging out, bolted in by a 10mm screw, the harness leads up to the lower power harness, where it splits to feed into the ECU, and to the speedo via the "engine room harness" to the SMJ to the Cluster. You can jump the signal directly to the input on the cluster, and forget about the one on the ECU.

***CrimsonRockett*** · 03-19-2007, 10:48 AM

My speedo works when it feels like it.

But, recently, when my speedo doesn't work my odometer doesn't work either.
