I didnt think the 99-03's had one of those. I thought that was an IDI only thing

Are they coming from the throttle pedal. If so its the TPS

that is an IVS. it tells the computer when the petal is starting to be pressed but before it starts the really tell what percentage its being pressed.

I read on another forum that the 99-01 has a IVS separate from the Accelerator position sensor, and in 2002 they combined both into one unit. I also heard that the sensors have a high failure rate and there is a big shortage of them right now.
