    As for the dealer level tool thing, that might turn on the PMW question.
    There is no question that the 12v side of the sender is PWM; that side of the sender is powered by battery voltage.
    The other side is powered by a 5v reference voltage that is created in the engine control module.
    If the throttle sender needs to be programmed to the vehicle, it will probably make this impossible unless the car only uses one sender, i.e.: my wife gives up her car

    She won't trade?

    For your car, I think you will need a throttle with both 5v ind and 12v PMW probably stock OEM.

    Incidentally I bought the whole bolt in drive by wire gas pedal, throttle for my then new van from Rockauto for the unbelievable price of $25.

    I have had periodic paralysis all my life. I lost my ability to walk in 2011 beginning with a spinal block, which was used for a hip fracture caused by periodic paralysis.

    Somehow I forgot the part that you have two stock senders. I think I got confused because I was thinking of the cool one you made.

    So as for the programming. can you mock it up without programming? I know on my little van when I replaced motors and switches in the sliding door the instructions said it would have to be reprogrammed. I went ahead anyway. It is fine. But those were not gas pedal, so no real safety issue to consider.
