Intermittently the VSC, ABS and engine warnings all appear together. The code reads left front wheel speed sensor. We’ve replaced the sensor and the related wiring. Still get the same code. Also replaced the ABS module and the yaw module. No luck. Any suggestions?

Good morning,

What was the code number?

Do you have a scan tool that can read live data from the ABS system?

Did you have the replacement module programmed to the car? That is required for it to work.

I attached a wiring diagram for you to view.
