>> I would run the TPS resistance measurements at the ETS connector to see if they check out (as is described in the TCS Manual) ... I assume you have verified the correct operation of the TPS safety switch (Pins 3/5) on the throttle. It should read ~27K closed and change to 500 ohms as you open the throttle.
Thanks for the info; I will test both tomorrow.
>> You also need to verify that the TPS motor (pins 1/7) show a continuous reading of less than 200 ohms as you move the throttle through its range.
I confirmed this; the resistance goes quite high between "stops," but never open. When settled, it remains below 200 Ohms. I have since popped the motor out and cleaned the brush area, the brushes have lots of life left!
