156/147 Abs sensor same ?

Are the 156/147 Abs sensor same ?
I broken my original sensor by jamming the gaiter jubilee clip between the hub n shaft so have replaced with a 2nd hand sensor from a 156 but it works untill i drive the car ... !?
Ive checked to see it the ring is damaged but its good
I fit the sensor and the abs dash light goes out, i manually rotate the disc and there's still no dash light, i put on the wheel and back 12 1 metres out the driver then go 2 yards forward and then the abs light comes on the dash, this has happened 3 times now and I've the MOT tomorrow ...
I thought i might be the connection so ive wired that but it's still the same ...
Any ideas ?

There are different types of sensors but basically same types fit to 147 and 156. There are however differences between front and rear sensors (one being longer than other) and of course left and right.

I'm still having trouble ..
If the car is parked and i unplug / replug the connections where the sensor plugs into the loom (under the bonnet) the abs lights on the dash goes out , Then i drive the car 5 metres it comes back on again so is it the plug or the sensor ?
It's a new sensor and I've checked the ring but there's no damage ..
I even cut off both connections and soldered the sensor to the loom but then the ABS light is on constant so Ive reattached the connections ..

Help ...

Have you had the fault code read?

It is possible that you've either got a dud replacement sensor or that the ABS ECU could actually be the cause of your problem. So before you do anything else, get yourself a diagnostic cable and MES and check the code! Just make sure the diagnostic cable you get can connect to the ABS ECU. Then report back here with the code(s) and we can go from there. I had to replace the ABS ECU in my GTV last year so I know the frustration!

Bought a proper Brand new Sensor with the correct part number and eveything is A ok, There's a difference in length between the 2 sensors so the 2nd hand 1 bought was propbably for the rear ...
