You will have a PM from me shortly

What should the reading be on a normal working sensor?

aT LAST !!! Sorted!

Following Keiths advice to get it on a T4, ABS fault log cleared and everythings back to normal, including my Sat Nav... thanx as usual to everyone

Depends on the type of sensor, ie passive or active.

Older sensors are passive: they are a coil of wire round a magnet. The ring or teeth on the hub cause a signal. They can be tested with the resistance setting of a multimeter. Problem is they don't work well at low speeds as the signal level gets really low.

Active sensors have a hall effect sensor with a magnet that moves. The sensor is supplied with voltage by the ECU and changes the current it draws as the magnet passes the sensor. The signal doesn't drop at low speeds. They are difficult to test with a meter, as measuring a resistance doesn't mean they are actually working.

Unfortunately for testing, the 75 uses the active type, so is harder to test! Most reliable test is swapping sensors.

Hi

my 2.5 v6 conny 1999 nad a intermitant fault from new that rover could not sort out it was the same fault as yours and was cured by a bosch dealer who replaced the twisted pairs wiring from the sensor to the modulator with a sheilded cable .

Thanks Mars - I have logged your solution, should the problem re-occur *-)

i too have abs fault,reading this thread im i right in thinking that the fault codes stored have to be cleared using T4 and will not auto clear once fault/sensor is replaced or repaired.

The codes on mine were cleared down and then ABS fault cleared.

Its worth a try but again the joys of electronics - it seems to work for some and not for others?

Good Luck
