Hello Guys and Girls it's 'Lurgs' here welcome to my channel and today how to
replace an ABS wheel speed sensor, right we best get cracking. The ABS sensor is
also known as the wheel speed sensor, all 4 wheels send information to the
computer and based on this the computer decides which wheels are locking up. The
sensors are also used for anti skid and on older vehicles they're also used for
the TPMS there's a link above now explaining how the TPMS system works.
Now if you've got this ABS light constantly lit on your dashboard it means you've
got a problem with your ABS system, now the first thing to check is the fuse
there should be a fuse for the ABS system, make sure it's not blown, if it's okay
then you need an OBD2 reader which sounds like a droid from Star Wars and
this should be able to read the error code so I've got a problem with my front
left wheel speed sensor and that's the one that we're going to replace out. So
you need to get the front wheel off and then locate the ABS wheel speed sensor
which on this model is here. Now what you're doing is you're basically just
tracking where the cable goes and it should be pretty obvious it should just
go in here just behind the disc. Now you might have a bit of a bit of a job
getting this out as obviously there's a lot of dirt and water going down there
so my advice is just spray some WD-40 on it and leave it for 10 or 15 minutes. So
remove that sensor, Oh hello, remove that sensor
I'm just gonna have a bit of a problem wiggling this one out because
it's probably been in there over 10 years so just get plenty of WD-40 on
there and I've actually got a pair of pliers on here just to give it a bit of
a wiggle just to give it a final force out and here it comes
lovely so it's now out and you can see it's pretty filthy so basically
clean that area up get a nice rag on there give it a good old clean and this
is the dirty old wheel speed sensor that we're gonna get rid of. Now don't take
the whole thing off because then when you go to put the new one on you'll think
ah where did it go what I do which is a good tip is just to replace it
bit by bit. So as you take the old one off you put the new one on. Now that nut
I've just taken out for the wheel speed sensor when I put that in I'm just going
to put a bit of copper grease on the threads oh and I'm just going a quick
cup of tea. If you're gonna be working on the motor
make sure you always have a lovely cup of tea. Okay so this is the ABS wheel
speed sensor that I've ordered I got this from a well-known auction site and
it was a fraction of the cost that I could get at any dealer or any car parts
local dealer in my local area. So at the moment I'm just matching it all that
making sure it is the correct model and it's all looking exactly the same
here. Obviously on your model it might be slightly different but make sure it's
identical to the one that you're replacing before you take it all to
pieces. So the blue connector here should just easily unplug, again that could be
filthy dirty so just give that a squirt and a clean with some WD-40
and get the new plug and plug that in
and then we'll start following the cable right round to just behind the disk so
let's just plug it in here good stuff. Right so now I'm going to start tracking
the cable following the existing cable and just removing the old one bit by bit
and replacing the new one in exactly the same place that way there's no issues of
oh where did this go where did that go, this bits too long not sure where
that plugged in just keeps it all nice and simple.
So let's get the new one into that plug there it goes. As you can see I've got them
side by side here the new one and the old one.
So I'm just tracking it around so you've got the new one there on the left-hand
side and the old one.
So on this particular model it's got a rubber clip there and it actually clips
on to the suspension mount there so I'm just going to pull that off and then tap
the new one in, so it just slots into there it's quite stiff fit so I'm just
going to get a hammer and just gently bang it into the into position and there
it goes. So the final piece of the jigsaw is the actual sensor and I'm going to
plug that directly in which I have there, I've got the nut to go in with the
copper grease on the threads so just tighten that up and just one final check
make sure it's all in place which it is so that's all looking good, and there is the
new wheel speed sensor is now installed. So what you need to do is you need to
replace the wheel, put the wheel back on and then the ABS light is still
alight but now if you go for a drive the computer should understand that it's
been fixed and the ABS light will disappear. If you found that video
