Customer Question

Traction control light is on and the cruise control light flashes but does not work also error code 66 is on. What could be the cause?

This error is for a speed sensor signal malfunction meaning one or more of the wheel speed sensors are not reporting speed to the abs module.Disconnect negative battery cable for 5 minuets and reconnect to see if code returns sometimes this code can be produced if wheels are spinning fast in a situation like being stuck. Thanks for your time.

Answer was totally useless ! Of course I had already reset the computer . Also error code 66 is a lean condition in bank one and two not for speed control sensor. Waste of time !!!!
