0 QinteQ Posted January 25, 2016 Report Share Posted January 25, 2016 You are right to eliminate the sensor before going further, Its usually one of the x4 wheel sensors http://ecx.images-amazon.com/images/I/417dKYISEnL.jpg - the second and less likely cause could be dirty phonic / tone rings on drive shafts- but usually the magnetic pickup shown below, usually you will not see damage to the black plastic coated sensor even if it is present- the easiest way is to find and test the particular sensor to see if it works. Do you know anyone with a diagnostic scanner capable of reading ABS on your year Chrysler ? I'm assuming your multimeter is auto ranging let us know here and we will tell you how to set the meter up : - you are testing ohms not volts- if you are in the UK start NSF 1st then OSF- you put the probes one on each pin - on the wheel side not the harness side- all x4 wheels should get around a steady read between 800 to 1800- the pins should be agnostic - make no difference which way round they are- if one reading on one wheel goes ever upward [not steady] its the one that needs replacing- if you do the other wheel you should get a similar variance on each wheel you test- flea-bay about £30 main-stealer about £80, both work ok, the Mopar part of course being the best risk Here's a walkthrough mate, best of luck. http://i.ebayimg.com/00/s/MTE4NFgxNjAw/z/h~cAAMXQVT9SzBL1/$_57.JPG Quote Link to comment Share on other sites More sharing options...
0 Semmysonic Posted January 25, 2016 Author Report Share Posted January 25, 2016 Thanks for the reply, very useful. I've had to replace a reluctor ring on my other car, had a quick look at them and they just seem a little corroded but not broken, wire brush got the worst of the debris off. Will break out the meter when the weather improves. Would this cause the traction control to switch off too? Quote Link to comment Share on other sites More sharing options...
0 QinteQ Posted January 25, 2016 Report Share Posted January 25, 2016 ABS monitors the sensors, and the TRAC reduces engine power and / or temporarily applying the brakes to that wheel to help that wheel / the car re-gain control - no ABS info - so it switches TRAK off.

0 bignev Posted January 25, 2016 Report Share Posted January 25, 2016 Yep I've had the ring changed on our 2002 GV, the ABS was kicking in all the ruddy time so had nearly no brakes!!And when my mrs kept driving through puddles in it to amuse the kids the ABS pump drowned,Easy fix, took the fuse out till it dried out.

0 Semmysonic Posted January 27, 2016 Author Report Share Posted January 27, 2016 I had a similar issue so I disconnected the one sensor to stop it temporarily. Rather have no abs than no brakes but MOT is coming around so got to sort it out Quote Link to comment Share on other sites More sharing options...

0 Semmysonic Posted January 27, 2016 Author Report Share Posted January 27, 2016 I will probably back with more questions soon :-D Quote Link to comment Share on other sites More sharing options...
0 Semmysonic Posted February 3, 2016 Author Report Share Posted February 3, 2016 Checked the from sensors, both read the same on the meter. Couldn't find the connector on the back ones but didn't get chance for a proper look as it was getting late and was losing the light Quote Link to comment Share on other sites More sharing options...
0 leeoliver2010 Posted April 9, 2016 Report Share Posted April 9, 2016 Just changed my abs sensor on front right was realy easy as long as bolts don't snap as mine did lots of lube and ebay sell Danso which is on for £25 so I'd change both fronts rather than 1 you could easily do it without taking wheel off I reckon Quote Link to comment Share on other sites More sharing options...
0 Semmysonic Posted April 10, 2016 Author Report Share Posted April 10, 2016 All sorted now, seems someone had tried to codge the offside front sensor in the past. decided to take it to a local diagnostics place to find out where the problem was, saved a lot of time and hassle Quote Link to comment Share on other sites More sharing options...

Question
Semmysonic
My abs light is on and traction control is off.
Want to try to find the problem myself before taking to a garage.
I'm guessing the sensors are the place to start, what's the best way of testing/checking them.
What next if the sensors are OK?
