ABS light Flashing traction light

[bobapple]

Now I know this has been covered before but never really found a resolve, basically sometime the abs light pops on and the yellow trac light us always flashing. The car got sent to Thor racing they said I had a code 22 and 33, 22 is a open short in solenoid of abs unit and 33 was a rear right wheel sensor. They tested the wheel sensor said it says it's working it pulsing. They also replaced the abs unit. They also checked ecu's throttle sensors and speed delimiters to no avail. So can anyone shed some light can a wheel sensor still pulse but throw up a error code? Please help not so arsed about getting the traction control going again but don't want the abs light popping up when it goes for a MoT .

Many Thanks

I had a problem like this on my car.. after changing the sensor twice I found it to be a faulty ABS ECU. Doesn't mean it'll be the same on yours though dude.

You can test the sensors yourself with a multimeter set to ohms, there`s a plug for each rear sensor behind the rear speaker panel in the back of the car,(you can just about unplug the sensor without removing all of the large panel), it may be an intermitent fault, either a break in the wire or something floating around in the hub, it only needs the smallest amount of metal particles stuck to the sensor to throw up an incorrect reading, it may be worth having a look at the sensor if it will come out of the hub, its common for them to seize in the hub though. Hope this helps.

Thanks for the replys gents apparently all ECU's were checked Thor replaced them with ones they had and no change. My next plan was to try some second hand sensors and I can garuantee mine will be stuck and I will have to destroy them to get them out. Can I just unplug the old sensors and plug the new one in with out removing the old ones from the hub just to see if it resolves the problem before I start hacking at the old sensors?

Thread resurrection, I've had a search but I may have missed something! Mine has started doing this this morning on the way to work. Its a facelift car with the snow mode on traction control. When the TCS light does start flashing, the car is acting like the wheels are actually slipping and there is no power there, it then eventually flicks on to the snow mode and drives normally. The ABS light and red triangle are only coming on for about 5 minutes then they go off. I'll try and check the codes later, but was just wondering if anyone else has encountered the same issue. I presume that temporarily, driving with traction off would stop the intermittant loss of power before snow mode kicks in? Cheers! Dan (Sorry if this is confusing!)
