Abs Problem

[Masked Marauder]

The ABS will work fine without the fault codes being re-set but next time the car is hooked up to the computer the fault will show as a stored error.

Linkgreen, Is is possible to explain in detail how you tested abs wheel sensor.

 

What pins/connections and multimeter settings, also did you test sensor in situ

 

Thanks

Hi Dieselalhambra

 

To test the sensors I traced back from each sensor to the electrical connector, disconnected the small connectors, (in the wheelarch for the front wheels and underneath the Gal for the rear wheels). Each sensor only has 2 pins, so I did a continuity check (resistance) check with the multimeter on the 2K range. Previous posts here had suggested the resistance should be around 1Kohm.

 

Results were:

3 X 1.076 Kohm

1 X open circuit - I did check for resistance up into the Megohms range but it still showed open cct.

 

So my logic says that I must have a duff sensor!!

 

It meant a bit of crawling about under the Gal for the rear ones, but once you get under there, its fairly strightforward to find everything. The 2 rear sensor connectors are almost next to each other, tucked away about 4 ft from the back along the centreline of the vehicle, in the region where the handbrake cable splits.

 

Hope this helps!!
