All you need is an ohm meter to check the TPS and you can do it with the carb on the engine. The manual in the FBC System section describes what to do and the resistance measurements you should get. Besides minimum values you want the ohms to increase gradually and evenly as the throttle is opened and closed through its entire range. Dead spots or erratic changes in measurements are signs of a bad TPS.
