Most likely, you have a short in the wire to one of your front hubs, or a spot on the wire where it has rubbed through the insulation and is making contact with some metal part of the suspension when the wheel is turned left. Get under the car and trace the wire from the hub as far as you can, pay close attention to anywhere it would flex when the wheel was turned.
This is a reasonably common problem.

I measured the garment over the sensors, both front of 1060 ohm . I moved the wiring, cleaned plugs and now turning the steering wheel to the right, the lights will be lit up.??

You need an oscilliscope or a meter that will graph the wave coming from the wheel speed sensor to properly diagnose a bad sensor, or a TechII.
I still think you have a broken wire because it happens when you turn the wheel. Check continuity between the hub end and the other end of the the wire while someone else turns the wheel.

Thanks.

Going to the diagnose, let them watch it.
I found a mistake, the left wire was broken. Hurray!!!
