The traction control light on a 2007 Chevy TrailBlazer often turns on without any apparent issues, which is usually due to a faulty sensor, like the wheel speed sensor or steering wheel position sensor. When the light comes on, a diagnostic code is typically stored, which can be read using an ABS scan tool. Replacing the wheel speed sensor may cost around $70 to $90 for labor and $500 to $550 for parts, while the steering wheel position sensor replacement could cost $100 to $130 for parts and $270 to $400 for labor. It is also possible to replace the steering wheel position sensor on your own using basic hand tools.
If there are problems with the traction control in a 2007 Chevy Trailblazer, it is possible that the speed sensor is faulty, which can affect the functioning of the all-wheel drive system.
