Rear ABS Sensor question

[Karl68s]

Just wondering if it is possible to fit a new sensor to the nearside rear without having to drop the tank.
Maybe tying a bit of string to the old cable and pulling it through attaching new and pulling back again.

I dont want to have to go buy another jack, axle stands, and drop the tank if I can avoid it.

Depends, if you want to do it properly and replace the whole part, then no. But if you are willing to fiddle a bit, then yes, simple:

-cut the wires in different lengths, so that when they cannot touch eachother
-put on some small diameter shrink wrap tubing on both wires and larger diameter on both sides of the cables
-solder the wires together
-pull up the shrink wrap tubes onto wires, heat them up to seal them
-pull up one of the larger tube wraps over the whole area where wires are joint and heat it up to seal
-do the same with remaining longer part of shrink wrap tube to ensure good seal

i drew a small diagram so you can exactly know what i meant. as a sidenote, make sure you put on the shrink wrap tubes before you solder the wires together. and another very important thing to consider is that wires colors might be messed up, so even if you connect red to red, black to black sensor will end up being connected in reverse, so test the wires first to make sure it is what it appears to be.

that happened to me, i connected red to red and in the end the abs sensor warning stayed, so i had to cut the cable again to reverse the wirese. to test the polarity, just get multimeter and set it to measure ohms, it will measure either 3.5 or 5.5 megaohms depending on polarity.

All that needs to be done is.

1. Remove the two 13mm bolts holding up the tank, they are located front and back of the tank.

2. On the right there is a 16mm stud, loosen off a couple of threads.

3. Next fit a socket or similar between the back tank strap and the back tank strap 13mm stud mounting and the chassis to keep the tank down enough so you can remove the sensor.

4. Just pull it out after disconnecting it.

5. Max a twenty minute job.

Think I'll be going with the cut n solder method, don't really want to be laying under the car messing with the tank, when I dont have any axle stands and only a scissor jack and a few bricks.

Cut and solder? Don't do it. Don't listen to anyone who tells you that. Firstly you're destroying a good sensor and then you're messing with something that can save your life.
As they say, its up to you.

david, with all due respect, butt soldering when done properly is as good and safe as any other connection method. if you will, many experienced repairman will tell you that it is even better than the wire nuts or barrel crimps, and yet there is at least a milion crimped wires on 407.

only bad thing about it that i ever heard was that it just takes too damn long to make, compared to other connecting methods. it cannot be vibrated apart, it wont get pulled apart, it wont short if protected properly.

and even if its a shoddy work and does go apart, only thing that will happen is you would end up in same situation as if your abs sensor failed, so yeah, you will know something happened and that you should look into it. just my 2c.

BUT it seems like alot of work compared with, undo a couple of bolts and unclip from under the seat.

Well I could do it right, but only if someone want to lend me axle stands and a couple of trolly jacks.
The cost of these I and the sensor and I might as well take it down to the main stealer to get it done

But as in a bit of soldering, I'm a dab hand with a soldering iron. I've spent many an afternoon soldering broken laptop circuit boards, hard drives ect to get vital information off them as a data recovery specialist in my spare time.

Personally I would rather butt solder then put some crimp connecters on or do an unsafe job and get under the car without the correct equipment.

Stealers will charge you about an hours labour to do a rear sensor
