Speedo not working - Phase 2 172 with ABS

[Gavin J]

Hey Guys,

Hit a bit of a dead end with this on the search function.

My speedo has never worked since i've had the car and after searching it appears it works from a sensor related to the ABS as apposed to a non ABS Clio's such a cup with works off a sensor on the gearbox.

Can anyone tell me anymore info on how the speedo the set up works on ABS models? and what i need to look for?

Cheers
Gav

What year is the car? If theres no ABS fault light shown and its an early (Y, 51, 02) car check is hasn't got a speedo sensor fitted. As the early ones hit and miss use speedo sensors instead of the abs and its usually the speedo sensor in the diff that fails to cause lack of speedo.

Hi
There is no speedo sensor although the wiring plug is there. Have brought a sensor but no way will it fit in the gearbox, my brothers 172 cup had his speedo stop working last weekend and fitted it to his no problem, on the cup with the sensor out you could see drive part in the box which on mine there is nothing their just a funny shaped hole, its a 2001

Well sound like it should be using a speedo sensor as otherwise the plug/loom wouldn't be there and they're wouldn't be a hole in the box casing either. Any chance of a pic?

ANy chance this could be a car that needs a speedo sensor thats had a new box, abs type before you bought it?

Thanks for all the responses guys/girls, its my kid brother so will get him to respond properly, from what i know it hasn't had a new box to be honest. its only off the back of mine having issues, and me using his part that he couldn't use to rectify his issue (Thanks gav ) , the only thoughts we had is that any prior repair work may mean the sensor may not be fixed to the abs on the motor.....like he said we have drawn a blank to be honest. Photo's to follow

 

[Gavin J]

Ok here's a photo,

As you can see the wiring/plug is there and it fits a speedo sensor no problem, but there is no way the speed sensor is going to fit in the recess pictured and no drive visible anyway.

The new gearbox theory could be a good one as i have no history with it so i can't verify if its had a box change.....

 

[cjewkes]

Still not managed to get it working?

 

[Hutchie]

that looks suspiciously like a incorrect box replacement prior to you acquiring the vehicle

hi. I think got the same problem with my 172 phase 2, 2001. the sensor must be in that hole?

cheers

 

[jinjur]

Yeah, there is no sensor there at all tbh........yet you have a cable for it.

Check that the hole is not a blank and if not, just get a sensor and hook it up

ok. tnx. will do that when rain stop

i think your car has had a incorrect box fitted as stated above, the wire IS NOT there if the car is ran from the ABS ring

you will see a small square plastic lug in the hole if it will take a speedo sdrive unit, IF NOT its defo wrong box ive seen 53 reg clios with this older type speedo input

I have the same problem, 51plate sport with abs just had new abs sensor fitted an cleaned all the ring an bottoms of the sensor an speedo jumps all over the place an the stops working for a few mins then pop back for like 30 secs then down again, I also have no wire or plug goin to my gear box!! ;/

Sorry to bump and old thread, but it's a decent return on Google and nice to keep the info in one place.

I have a Speedo that's just dead, doesn't even read momentarily. I took this picture last night which I believe is the gearbox sender

So knowing I have the correct box in the correct car, can anyone tell me where to look next? Is it likely a fuse, or the sender and how would I check?

Thanks

There should be a heat shield on the sensor to protect it from the manifold heat. Chances are it's been cooked.

 

[alistairolsen]

Is it a geared system or an inductive pickup?

 

[Vaughan]

Inductive.

 

[alistairolsen]

Found a used heatsheild and a new genuine sensor for £20 so I'll fit those and see if that sorts it.

I'll also try this

To check the gauges sweep
