Replacement of ABS sensors for a V6!
Hawkmoon hat geschrieben:Hi guys,
Over recent weeks I've posted stuff about wear sensors and ABS sensors and so on, all because I've the wonderful loving glow of the ABS alarm on the dashboard!
Plugging in Vauxsqueeks MDI (tool) reported that the off side (drivers side) sensor was 'open circuit or short'.
An ABS sensor from Vauxhall is £264 each, so thats £528 for the sensors and £90 an hour plus VAT - 2hrs work a side .... !!
Bell testing the wires on that sensor verified the wires were fine and reading this post from 'keefy D' allowed me to test the sensor and verify it was knackered and the best part of the post is it offers a fix that does not cost the Earth!

The MDI sadly also reported the same message for the near side, repeating the same tests confirmed that that sensor was also dead so I needed to replace both the ABS sensors.
So as per 'Keefy D' and what he did I ordered the parts and did the same!!
Total cost, £40 and a few hours with a mate in the sun!!
Here is one of the enemies after cleaning ready for removal!:
To get here, the Hub had to be removed, which thanks to the rubbish metal used some of the screws which need to come off then stripped or rounded and had to be drilled out! (3mm HSS drill bit)
My advise is to buy the screws in advance of this operation so they can be replaced when you put it all together again! :thumbup:
[Part number is - 97810107. (a pack of ten for a little less than £10!!)]
The hole to the left of the sensor is the 'bottom' of a 5mm Allen bolt that is as stiff as hell, and you really REALLY need to drown it in WD-40 to have a hope of having it release, or you will have to drill it out as well!!
Sadly one Allen bolt I had to drill out the other released happily after a good soak!
(I will wish you good luck when/if you do yours!)
The hole is not fully threaded!
Bloody daft I know but its threaded about 3/4 the way not all the way, so any replacement bolt needs to account for that or you thread the whole thing, upto you.
So first things first!
Remove the brackets from the new MAZDA sensor, you don't need them, now ream the fixing point to fit the Vauxhall!
(A home made pillar drill lets you remove some metal to let the holes match up! 5mm HSS drill into a block of wood, held firm and straight!)
The MAZDA sensor when measured is NOT 2.4'ish ohms, its 1.2'ish ohms ...this is OK!
On the car cut the RED & BLACK wires (NOT the Blue and White, these belong the wear sensors)
Connect the new sensor wires to these and test.
(Any way around is fine, the sensor is a coil so like a light bulb it works either way around!)
Then thread the wires along the original ABS wire path and secure with cable ties, now crimp the wires into place and tape up and make sure its water tight!
When fitted you will note this:
(This side came apart great!)
Its also ok, so long as its bolted firm its will not move the sensor will work and report a signal for the ABS ECU to read!
The other side of my v6 looks like this:
(it had to be drilled and a new bolt installed!)
Then new some new grease and put it all back together again!
Start the car, and ta-dah!
