yeah they're bolted to the wheel bearing/caliper carriers, follow any wires to the wheel area and you';ll spot em. sometimes can get away with cleaning the sensor and the trigger wheel, sometimes one or both need replacing. while the wheel is off take a good look at the trigger wheel, if it looks ropey then advisable to change it. in an ideal world they're swapped whenever discs are changed, but this doesn't always happen

just had the wheels off found the sensors the prob looked obvious apart from needing new discs soon a load of chunks of rust was spinning round in the disc and getting trapped in the sensor wheel holes.
got them out erased the codes and all seems ok so far.
thanks
