Abs & Traction sensor fault - stecw12
hi having a problem with my abs light coming on, had my car on a dynostic laptop which said it was my near side rear abs sensor needing to be replaced, but that didnt cure the problem, any ideas, could it be a 'ghost problem'. it comes on when ever it feels like it!!
traction light comes on to, been told they are on the same ciruit...
apart from this little niggle, great car. thanks for any help on this topic, if i go to mazda i could be spending hundreds if not 2 thousand (a faulty ECU)

Abs & Traction sensor fault - Raman
Hi, I have a Mazda 323F on a 2002 plate. The ABS light came on. I found which ABS sensor was faulty by disconnecting each one and measuring the resistance. Can't really remember what the value is suppose to be but have a look at this web site
protege5.ugly.net/#gen.

Mine turned out to be a rear passenger side ABS sensor faulty. Replacing it is not very hard.
Hope this helps

You've fallen into a very common trap. The fault-code would never say that the sensor needed replacement; it would have said that there was an unspecified problem with the left-hand rear sensor circuit or signal.

Fault codes are only a guide; so the next essential step is to physically check the circuit and signal. When you found it acceptable, then checking the others is might have shown a disparity.
