How many ABS sensors LR2 discovery2002 has?

How many ABS sensors does the LR2 discovery 2002 has.?
how often do they go bad?
 
I got the three lights on, the 3 amigos, HDC, TC, and ABS.
The mechanic checked it and ren the diagnostic.  His result was, the 2 front ABS sensors need to be replaced and that the right axle is missing a teeth, because the the right ABS sensor sits on top of it, it is triggering these thre lights. He said that  the axle also needs to be replaced too. I am not sure if that is the case I am worry becuse he is charging over 1,500. dollars including labor to fix it. Any suggestion? please!!!!

Your mechanic is so full of CRAP, I can't believe he could dream up such a story.
How many miles on your truck? If you break hard, can you still feel the ABS pulsation thru the brake pedal?
By the way, you have one sensor on each wheel.
Don't do anything till we talk some more.

New axles for ABS fault.............. I like that one!!!............lol. You can actually test the ABS sensors yourself, its unlikely 2 sensors are bringing on the lights, more than likely 1 duff sensor, but it could even be the wiring to one of them, a dirty sensor etc or worn hub, or a sensor is "loose" in its mounting.

To test the sensors in a "primitive way", simple disconnect each one in turn, and measure the resistance across them, 3 will be almost the same,and the faulty one (which i supect is your problem) will give a very different reading, ie to high or low resistance. This is basically all the Diagnostic machine and the SLABS ECU does to test them.

The actual resistance of the sensors should be 950-1100 ohms, anything outside that value either higher or lower will fail the SLABS ECU test and illuminate all 3 amigo's

Thanks Mike and Urban I am with you, my trcuk has 50,000 k miles Mike and yes I stll feel pulsation thru the brake pedal. thanks you so much
 
also Urban I will take your advice in consideration too and try to test the sensors
 
thanks guys I feel much better now.

Now the trick will be to get the mechanic to clear the codes. He may not want to do that, makes him look bad when they come on again.

Thanks Mike,
they tried to clear the code, but It comes back again, so I guess I will check the sensors to see it they need to be clean or to measure the resistance to find out which one is making these lights to come on right?
 
what do you think?
 
 

This is starting to get interesting. Let me know what you find.
