ABS light on 94 E420
 

Guys,
my ABS light comes on intermitently, ABS works fine and I have a feeling I need to replace the sensor. Is anyone familiar with this problem, location of the sensor?

Thanks, YO

Maybe need to just clean the wheel speed sensors? I'd pull the front ones-they're easy to get to, 2 screws hold each in place...look behind your backing plate-follow the wire:)

Very common for an intermittant ABS light to indicate a charging system problem. Too low voltage won't allow the ABS pump to operate properly, so the ABS faults when the charging system is beginning to fail.

Usually, ABS sensor problems are shown as ABS "functioning" at very slow speeds.

Try cleaning the ABS sensors, but unlikely...

I would have the charging system load tested first, as this is usually the problem that causes the symptom you have described.

Along with checking the fuse on top of the Over Voltage Relay.....

Scratch my last post...just noticed you have the 420---- no OVP

Wires leading to the hub...follow 'em.
