Where can I find the ABS sensor?

[carrmrc96]

My speedo has stopped working so I was gonna check the ABS sensor, does anyone know where to find it?

Theres 4, one on each wheel. Mounted on the hub behind the disc, held on by a T-30 torx bolt.

 

[carrmrc96]

Do you know which one the speedo works off?

 

[bmh.01]

No idea i'm afraid, edde might know. Offside front comes to mind but i've got no idea where from, may use a combo of all four.

my mate had a problem with their speedo and was told by a garage that it was caused by the battery being detatched for so long but i dont think this is true! and i dont know how they fixed it either!

There talking rubish.

The system uses the front left wheel sensor but it does take account of the rest of the wheels.

Do the trip computer diagnostic trick first and watch your dials dance to make sure its not the dial unit thats fauty.

Yeh i done that and the instrument panel is working fine.

Check the wire at the back of the dashbaord then. IE remove the dash top etc.

 

[carrmrc96]

Ive removed the dash as well and the wires were all fine. the earth point was all tight.

Check the plug on the ABS unit under the bonet.

 

[carrmrc96]

Checked that but it seems fine. Does anyone know where The ABS sensor is or what it looks like?

Theres one on easy hub.

There only two pipes to the hub one thin one the ABS wire the other the brake line just follow the ABS line.

not poo pooing what your saying edde but how does it work on a cup then as there are no sensors at all for the ABS,

i thought it was a senor in the gear box which reads from a cog in there ?


but then again im not a mechanic but its certainly not the battery thingy.

 

[benji&eka]

cup is different

 

[Big Bob]

cup is different

is it ?


i know that but how.

It doesn't use ABS so has a sensor in the gearbox. All the other Mk2 speedos work off the ABS.

Yep theres a speedo sensor in the gearbox. Hence why you need to make sure its a cup gearbox when you need a new one.

All the Ph2 onwards barring the cup use the ABS. But I think some of the Ph1s that predate multiplexed wiring are using speedo sensors as well.
