TCS lights on

Have a 2003 Honda Odyssey. Had 2 snow tires put on and alignment. After it was done, my abs and TCS lights were on. Am told I need a front left ABS sensor. Seems odd it happened immediately after repairs. Two different shops, one did tire, first had two snow tires put on, drove it literally across the street to have the alignment done. Alignment shop says ABS lights were on when it got there. Tire place says it was fine when it left their shop. I didn't notice as steering wheel is in direct line of sight between me and lights.
