I was doing some testing on my car and checked the operation of the throttle position sensor by looking at pin 52 of the DME harness and ground. With the throttle closed, my understanding is there should be zero ohms. Mine was open, but if I put a little pressure on the throttle towards the closed position, I see zero ohms. Doing this I can also hear an audible click when the pressure is applied. When I turn the key to the on position, the idle control valve buzzed (without continuity of 52 to ground). Does the DME need to see the throttle position sensor with continuity to turn on?
The car runs fine except does have rare spells where it either dies suddenly (and starts right back up) or will not start easily. It never has left me stranded.
