Have you cleared the stored fault?

They are magnetic if you put a multimeter on them then wave metal across the tip you will get a change in reading. However to get the sensor to work on the system it needs a 5 volt feed from the ECU.
 
iv cleared the fault every time it appears with autologic comp I checked the volts to it before I changed the sensor and I had 5.02 both sides thanks mike
 
both it comes up abs fault and traction failure on start up I drive down the road sometimes it bings up with out me braking etc then other times it bings up if I brake hard
 
yes it was a cheap sensor from ebay I think il swap it side to side and see if it changes the fault to the other side
 
Having just had abs tc errors on my p38 5 mins after just passing its mot, lights and tc came on replaced the accumulator no difference, was 2 dud sensors from ebay only new last year..

Found out they were at fault with a multimeter set to ohms and the sensors still in place un pluged each one to look for a solid reading, back ones where .900 each front ones ebay ones were up and down and in 1.2 then down to .03 and such. Ordered 2 news ones tested on meter before fitting both fixed reading at .900 flat fitted them and abs tc been off since

Hope this can help a little
