Peugeot 206 Speedo not working everything else works!

[Galee]

Hi can anyone advise I have a 2002 Peugeot 206 petrol here that the speedo does not work on. I have fitted a new gearbox drive but is still the same. I know the speedo works as I have had it working though the Launch X431 doing a actuator test. So I take it must be the wiring I had a quick look on the autodata and it appears the 3 wires that come off the gearbox drive one goes to fuse 1 in the fuse box and one goes to the - and the 3rd wire goes to the ecu. Does anyone know what pin on the ecu the 3rd wire goes to or any common faults or places I should be looking?
Cheers

would guess that the 3 wires are 12volt pos, neg, out to engine ecu and speedo.

probe these wires and then yank like ~~~~ on them and hope it breakes had them go over the bell-end housing

What engine/ecu does it have? Sometimes the road speed comes from ABS and is also shared with engine.

try fitting a second hand fuse box not a bsi
i had a c3 with same fault
the feeds were fine to the speedo drive but the sensor wire went to the fusebox then to electronic steering and clocks

and if it has a speedo drive then no abs intervention abs if it had it then it would have a blanking plate where drive goes in the gearbox
worth a go and fusebox is plug and play

sorry caps lock

Well thanks for the input guys this is where I am at I have traced the wires from the gear box drive and have a grey and red wire which is pulsing when driving this wire comes from the gearbox drive so must be the speed signal. This goes to the engine bay fuse box then goes into the car this is then a white wire. I have traced this to a plug next to the bsi unit on the drivers side. It is a grey plug with one wire going in and a plug on the end with no wires. which has no wires coming out the other connnecter Which makes me think something is missing! I have the white wire up next to the inside fuse box/bsi but the other end goes to nothing and I can't find no broken damaged ripped wires. Yet if I do a actuator test with the Launch it works fine but I don't get any pulsing from the speed sensor wire. How does this sytem work? The car is a 2002 1.4 206 no abs.

Speedo heads were a real problem with these cars

Whoops, meant to tell you that, often say hello to the single wire on it's own.

One of them things you just can't forget, sorry forgot about it.

*THINK*THE speed pulse is pin 20 on the speedo head, just got to
pop out and get another ~~~~ mag, so not got time to look it up.

[Galee]

Right thought I have better get back on this as it has been sitting in the yard since May the last time I looked at it.

Well this is where I am I have traced the speed signal wire grey/red from the speed sensor in the gearbox to the Engine fuse box to the Noir Black Connector Pin 14 from here it seems to come out of the fuse box at the EP1 connector pin 2 White wire this goes into the car and comes out down by the bsi unit to a Grey plug. Mounted next to the bsi with nothing on the end and no wires coming from it. It is just cliped on like all the other plugs down there like for the transponder / air bag connectors and all the others and everything else but this one grey plug has nothing coming from it just the white wire going to it from the engine fuse box.

Racin-snake you say you had the same fault on a C2 did the speed signal wire exit the c2 fuse box at 2 or more locations?
What I mean is that I only have the speed signaL wire coming out of the fuse box on the white wire on connector EP1 Pin 2 and nowhere else could this be the problem?

Meat-Head speed pulse can't be pin 20 as the speedo head plug only has 18 hole connector and 12 wires going to it.

Thanks for any ideas or advice on this guys.

i had a 206, same problem, blown fuse in fusebox

in diag machine, check in live data to see if there is vehicle speed present

if someone has been tryin 2 correct the mileage, they hav most likely damaged the motor (common fault)

[Galee]

Z786 Thanks Okay tryed that and speed reading is 0 kph in the live data, But surely if motor was blown in the speeDo head the launch x431 could not make the speedo work using the actuator in its menus. This makes the speed read on the speedo all the way round when testing so this must mean the speedo head is good?

a) Just to point out you mean drive the car
b) you mean an milage 'incorrection'
c) Thought that counts

[ziggystardust]

thief before the fuse and make a direct wiring to the speedo and se what happens , if it not work make a other thief connection and put 240 volt's of pure energi and claim that the francois has made an self-burning super-duper poff to it self .
try to re-wiring is my advice mate :-)

[z786]

like MH said, was you driving the car when you rea live data?

if needle moves in actaution then speedo is fine

if the reading of 0kph was while driving then i would check speed sensor

did you check the fuses?

DENSE QUESTION:

Does the milage go up? - This question refers to you driving the car

[Galee]

Hi guys when driving the car the trip meter or mileage does not go up and the speedo itself does not go up also the live data test was carryout while driving and no speed output shown on the launch only 0kph.

Was thinking of wiring direct from the pulse wire that I traced to the plug next to the bsi to the speedo but unsure which wire to attach to on the speedo head. And not sure if it needs to come through the bsi to the speedo via can lines does anyone know?

[racin-snake]

the one i had was a digital speedo head and the purple wire in this case went to the fusebox under the bonnet fron speedo drive
then went to the ecu and finaly split to go to power steering module
i scoped the sensor and it was working so went to the fusebox fine there too
live data on planet worked the speedo on actuators in dash module
so checked the wiring from bsi to speedo all ok and it did work fine ( as it did i when actuated with planet )
so got a fusebox (*WHICH IS PLUG AND PLAY )
and fitted ....speedo worked fine after that
maybe same problem ,,maybe not but in theory testing should be similiar ?

[cars]

Dear "Galee" if you post me your VIN number I can give you the wiring diagram right.

[agabna]

hello
some 206 the speed come from the abs through the bsi
first you have to check the configration of the brak system espicaly the brak bads types what type you have because if their is any wrong in the configration for the abs the speed will not work
that happend to me and i had take complet month to do it
so check all the configrations using the PPS

[racin-snake]

dont think this one has abs as in the first post it says its got speed sensor in the gearbox ..
but in config check its gt a manual box specified and not auto .... worth a look anyway ?

Km meter advances? or just speed needle doesnt work?
sometimes this dashboards have 2 conectors, yellow and white i believe.
The problm with this dash are the motors that drive RPM and speed needles.
check them. turn the needle and should move smooth. if it doesnt move smooth you need to replace motors.

Would like to refresh this thread for educational or entertainment purposes please.

Did the Orginal Poster fix this?

[Liteace]

Im sure it would have been the FET's in the dash, common problem with these shite Pugs

No, it's had a previosly enjoyed speedo - IN-corrected by M-H-M
Costomer installed speedo snesor.

Would be nice to know what OP found.

Now have spotted another 206 in the 'long term bay' in the mulit story car park over the road, do tomorow, it's going to go walkies.

[Meat-Head]

Right, would like to RE-bump this thread.

so far, we have only thing we havent tried is coms2000 and basi of the EXCAT number.

any more suggestions?

[sazimam11]

Had the same problem recently. The fault was broken axle of magnetic actuator of the tacho. The part you need looks like this. (http://www.automotoelektronika.cz/files/Mot%20Jaeger%20velky%20plast.JPG?rand=586174205) Hope this helps.

[Meat-Head]

this one has had the head changed AND you can drive with diagnostic computer.

[Meat-Head]

:stupid:CAUTION - HIJACKED THREAD.

Right finally got round to this one.

Right looks like, the speedo sender on the box pulsese to the under bonnet fusebox thing.

this APPEARS to be then

1) come out as a didigital signal

2) Comes out as an analogue signal.

When exiting the underhood fuse box, it goes towards the bulkhead, then theres a joint - not quite in line with the trafficator on the wing, in the loom, then wires splits 3 ways

1) Hangs a left in to a yello into the engine ECU
2) Grey straight inside to a blank connector below steering colon
3) turns into think a gay purple color that *THINK* goes to the airbag module.

It would appear it needs somekind of 'load' from the engine ecu for the speedo to work.

Damm Frogench.

This one the joint was full of wet stuff out the sky and had only just gone, so no signal to engine ecu, but had a pulse when probed, damm frogench. :stupid::stupid:

[borysgo2]

Sppedo drive signal wire is going to bm34 fusebox black 16v connector pin no 14, threw fuseshitbox is going out from 20pin black connector (as far remember pin 2) to ecu, than from ecu speed is transfered over can network.

also check configurations for the right setup there ie gearbox and the wired /abs options

yes, good point, but it was one of them jobs, where we spent a lot of off-line time on it, charged 4 hours labor :roflmao:

[bobby87]

I had a similar problem with a berlingo turned out to be the ecu speedo signal going in and not coming out.
