43 RH Front Speed Sensor ( Resistance & Connections )

What you need to do is follow the sensor back to the connection plug, undo it there, then do the same the other side, and with a multimeter check the resistance across the plug going to the actual sensor. the good side should show you roughly what to expect from the dodgy one, if they're similar you know its a wiring fault from the other connector back to the abs unit(unlikely), if they're not similar or there is nothing at all to the sensor you know you need a new sensor.. I seem to recall that some people have had issues with the wire snapping near the connector, so it could be worth chopping off a couple of inches and testing it ther,e you might get away just putting a new plug on it. but i expect its knackered.
