    Possible. Work on some P/U's at times. Hand with a scanner can push buttons and read vehicle speed off of each individual ABS wheel sensor. Post the last 6 of your vin and someone can likely help you more. Sometimes that takes some time.
     
    Laureano Thanks this.

    If no sensor in tailhousing and a manual trans , good chance vehicle speed is datalinked from ABS controller. So, the answer is yes your Wheel speed sensors could be your main source of vehicle speed.

    I think the main question is- whats not working or what are you trying to fix?
