Hopefully your crank sensor is not located on gearbox as you placed it in your post! VOLVO puts their VSS on the inboard side of an output shaft, usually. You should be looking at the axles, and the holes in the transaxle they extend out of... There will be a sensor reading the inner end of one of these output shafts (axles.) This is your VSS. It operates independently of your ABS, but its accuracy is vital to the ABS's proper function. Its reading is used for many things in the car, not the least of which is speedometer readout. Hope this helps, let me know if you don't see it, I'll get you a more exact location if need be, but if you look carefully, you'll find it. It's reading the speed of one of those axles, but not at the wheel, at the transaxle, get it???

All my dash lights are on and no odometer


car runs? and moves?
headlights work (full bright not dim) all lights work.
you key on, and the warning lights glow, and the CEL lamp too.
that is first.
then the odometer
no OD
means what ( blank, stuck, wont roll if mechancal?)
the odometer must work on all cars if the speedo works
so does speedo work?

ill look up the system now, varies by year.
first off , all answers USA cars on this USA forum.
cant do others. ever.
omg its GM car, in sheep skins...
s10../blazer
what engine, you do know systems vary by ENGINE. in car.
ill guess. now.
4.3L engine
the ECU has a 2 wire connection to the VSS sensor (speed)
so that means the ECU sees all speeds and sends those to the
cluster and odometer.
it uses 2 wires to the cluster to talk.

the first wise step on all cars is to check fuses.
then scan the OBD2 port
if the scan shows VSS dead, it is. P0502 or P0503?
end story, fix VSS, (replace it or clean it)
if no errors with VSS and speedo works (do says so.....?????_)
then the odometer is messed up. (not good that)

the books says if any part of cluster is bad. the whole cluster must be changed out.
but fails to say, (bad) that if MPH and ODOMETER
are dead., the VSS is bad. and the scan tool told you that.
all scan tools sold work here,
why not scan it first like we all do.....(never work blinds)

Does my 1996 honda accord have a vehicle speed sensor


most old cars have a speedo cable.
is the odometer dead too. (we need that answer now)

there are 3 class evolutionary systems.
cable
electric sender to cluster
and sender to PCM and PCM drives cluster.
but honda does this on diffr, dates than most cars. (i learned)

so lets do that. we login to alldata.com and look , so can you at any time,
once a month i do random cars.
what engine, sometimes this varies by engine, and trans.
neither stated so Ill toss coin each time.
a/t trans.
1996
has electronic (hall) speed sensor VSS and runs
engine, cruise. odometer and cluster.

the 96 has no speedo cable, and works in modern mode, very advance for this time
also any scan tool on earth fits the PCM scan port
and if VSS is dead, it tells you that with a DTC , vss dead.
saving all that work wondering why it dont work.
see/?
PCM must see it work
and cluster
and cruise
if only cluster fails, and both speedo and odometer then its bad.
if only speedo fails but not odometer , then speedo meter is bad.
its that easy.

Speedometer quick qorking 2004 usuzu rodeo 3.5


did you connect any OBD2 scan tool and look.
the PCM will tell you if the VSS is dead. flat out tell you.
why no scan the PCM and not work blind./??
the tool is cheap to buy, rent or loan. (or any mech will just do it for free as good will. (no dealers here).

ok, Rodeo, 3.5 2004
3.5L is wrong, dead wrong, 3.2 is my guess.
see here, see country and engines, neither i can guess.
http://en.wikipedia.org/wiki/Isuzu_Wizard
which engine ReALLY ?
Not the Rodeo SPORT , answers below are 3.2L non sport.

Speedo dead. what about Odometer.?????
is replace sensor a statement or a question?
replaced with a "d"
my guess it was a question. and guess.
step 1 and 2 all electrical problems.
1: test the fuses, related. Fuse #11?
2: battery fully charged, at 12.6vdc, not 10v, at 10 electronincs dont work right. fix battery. or charge system.

now how does the 04 work.?
the VSS sensor feed data to many things.
PCM (for fueling data)
Speedometer
Odometer
ABS
supension control unit.
cruise control
etc.

if the odometer works its not the VSS.
see?
the cluster is 100% electronic, ....

VSS is input to Speedo and the odometer is electronic inside
same, so if VSS is bad, both die.
fact.
if only the speedo is bad, then it is bad.

scan the PCM and not guess.
the PCM reports a bad VSS, with 100% assurance.

Speed odometer


LSI 4cylinder or 3cylinder? engine. , all answer USA cars.
all answers now, are 3cylinder

did the odometer quiet too?
key fact
and in USA< connect any scan tool and see if VSS died.

the usa 96, 1.0L 3cyl has the VSS sensor in the speedo
and when the cable snaps, Speedo to transaxle flex drive cable.
snamps
the speed goes dead
the odometer goes dead
and Vss goes dead.
easy huh, if all 3 are dead.
but if speedo ONLY goes dead, that means ITS dead.
vss= veh.speed sensor. or MPH sensor.

Transmission Fault code 17


a real DTC code.
17 , 94 Accord
the means VSS is dead, vehical speed sensor (miles per hour)
so , that begs the question is the speedometer dead or odometer
dead or acting funny IN ANY WAY?
is this an A/T Car or M/T car, both have VSS, so... cant answer.
Auto or stick, ill pretend, AUTO.
VSS moves all over the place, in all cars. all models and all years.
on this car, its odd.
quote FSM:
Accords and Preludes use an external sensor mounted on top of the power steering speed sensor in the engine compartment. The power steering speed sensor is gear-driven and controls the steering boost in relation to the speed of the vehicle. An electric pulser unit is mounted on top of this unit and is coupled to it by a small shaft. The motion from the lower unit is transferred to the upper unit; the resultant electrical signal is sent to the appropriate control units.

most cars old use the speedometer VSS sensor inside
on newer cars 1996 (on avg) the sensor is on the tail shaft. and in speedo.
on very new cars there are 3 VSS.... (dont ask)

on my 96 car, the tranny VSS can fail and then FALL back to the
SPEEDO head. and tranny still shifts but is funky,
the FSM covers all this, i recommend getting one, to understand
how it all works.

your car has and electronic speedometer
the VSS orange wire , sends speed data to the PCM, TCM, cruise.
the PCM then sets the speedo dial, and uses this info to run TCM
controls to the transmission.
your orange wire signal is dead or flaky.

Speed sensor


there are many on some cars 5 or more.
what engine,? what transmission?
1: crank shaft rpm CKP sensor.
2: VSS 1 tranny front sensor Automatics.
3: vss 2 tranny rear. """
4:speedo back up VSS to vss 1.
5: cam speed, or Angle.

why not say the symptoms and why VSS is on your mind.
did you use a scan tool, if not why not?
the scan tool will tell you which sensors readings are wrong
and just because one is, dont mean the sensor is bad.
the PCM /ECU never knows what is bad, ONLY what tests
failed (called monitors) and its the job of the technician
to do the FSM tests. and find TRUE CAUSE.


SCAN it and stop guessing, or go broke.

How To Replace The VSS

The VSS may be the issue. VSS is Vehical Speed Sensor. You can do it yourself , but you will need a torxs bit with the tiny hole in the bit as the bolt has a small stud in the middle of it. also the VSS is not located on the tranny its located on the diff and anybody who is fixing it you do not need to undo the power steering hoses, and make sure you have a T20 socket as you will not get anything done with out it. Also the screws that hold the sensor in a a ***** to get out be carefull of striping them.

Speedo not working is the autotrans on this modle


VSS (vehicle speed sensor) electronic, located on the transaxle. The pic is from a 94 Accord, but it should be close to yours. It's not a great pic, but it should help you find the VSS.

Intermittent Speedometer Operation


Your vehicle has the 4T60E transmission,and there is a speed sensor mounted on the transmission case that the vehicle's computer uses to compute vehicle speed,and relay it to the dash mounted speedometer.The best way to diagnose this problem is to first,hook up a scan tool that is available at automotive repair shops,and scan the vehicle for trouble codes first.Your vehicle probably has a stored trouble code along the lines of a Vehicle Speed Sensor (VSS).After pulling codes,go to the data stream on the scan tool and look at the VSS signal that the computer is seeing,and when the speedo acts up,and stops working,look to see if the computer is seeing,a speed signal.If the vehicle computer is seeing a speed signal,then it's probably the speedo in the dash gone bad.If the vehicle computer is not seeing a speed signal,then it is likely a problem with the speed sensor mounted on the transmission,or the wires right before it.So,to diagnose really requires a scan tool,with a data stream,or you could just have the speed sensor replaced,and hope that fixes it.The speed sensor is located on the passenger side of the transmission,only accessible from under the car,but where the pass side axle actually goes into the transmission,the sensor is directly above that point,and retained in the case with a 10 mm bolt.It has two wires going to it.Good luck.

Abs require service


The code is for the Vehicle Speed Signal (VSS). The VSS is produced by the ABS electronic control unit by averaging wheel speed sensor inputs and sending a digital signal via CAN bus to other modules that use the VSS. To test the ABS, a Volvo-compatible scan tool is necessary. If one is not available, the car should be sent to a Volvo dealer for ABS diagnosis. I can tell you however that most of the cars are fixed by replacing the ABS Control Module.
