Hi - its a new sensor and bearing (had fault before these were replaced. I reckon there is a wiring problem from the sensor connection to the ABS unit. There isn't a reactor ring on this model.
Does anyone know if the wiring from the sensor goes in to the vehicle via a hole/grommet in the bulkhead or does it go straight to the ABS unit?
 
New does not necessarily mean working. I've seen a few bad parts from new in various categories.
 
Yeah I agree but its the second new one and I've swapped it with the osf sensor and that reads fine - still poor reading on the NSF.
 
My car has an earlier ABS system, but have replaced both front wheel speed sensors, one reluctor ring and the G-sensor. Hilariously, I am now getting the intermittent two-amigos, which likely means I have a fault on the brake switch...

All this stuff is relatively easy - so long as you have the right kind of diagnostic kit. I am using a pscan.eu (I have other MG Rovers of the same age, so it is absolutely perfect). It has the same functionality as Testbook - the OEM fault code reader - but there are other units available. Not sure what the other guys here prefer?

Hi Rob - thanks for the tip - I haven't replaced the G sensor (yet!). awaiting brake pedal switch and then I will test again. I use an Autel Unit (not sure what model it is but its a fairly good one (£1200 new although I got direct from Autel refurbished at £400). I also have access to a new Snap On Diagnostic machine which cost 3 times that. I believe tho that some of the cheaper ones can be just as good so its not always about money/cost.
 
COVID restrictions permitting, we're planning to be down in Watergate Bay this coming weekend. Would be great to catch up with you, Nodge and everyone else (family permitting!) I could take my pscan and compare notes, but if the fault reader says it is a speed sensor fault, that'll be it I think. From memory, "electrical fault" generally means it thinks the sensor is dead. Which could mean a loom break somewhere?
 
I bought a new cheap sensor and still had the same issue, I bought an expensive sensor and the problem went away and stayed away
