    I took my truck offroading and a little mudding last weekend and now my ABS lights are on. I don't want to take in to the shop (I would if I have to....) I just want to know what some of ya'll think the problem is?

    Just try washing the wheels/brakes out. I had this happen on my Ford Ranger once during a snow storm and it turns out it was just snow and crud on the ABS sensor.

    Most probable reason.
    Worst case scenario, broken wire.

    The light turned off for 1/2 a day then it turned back on. I took it to the wash the other day and sprayed it real good but the light stayed one. I hope its a dirty sensor and not the broken wire.....If that's the case what am I looking at to repair that problem?

    I kind of brain farted that the actual sensor may be damaged, as well.

    In your instance, I'd remove the tires and you'll see the sensor with two wires running to it. Possibly use some soapy water in a spray bottle to clean the sensor, but i don't think that'll help. From what I gather from the schematics it a magnetic pickup. If you go 4 wheeling in a soil known to contain iron or any magnetic material, it may do the trick.
    I do not know the senor testing procedure, the FSM may have it, I did not look.
    The wires, if the connectors are still serviceable, is an easy fix. Just re-splice the wires and seal with heat wrap.
    A defective sensor is a replacement you should be able to do yourself with basic knowledge. I do not know the price from Toyota, though. That could be the costly part.
    Check the Factory Service Manual. It's full of testing procedures for this and all the other systems on your truck.


    Hope that helps!
