There's no need to set you TPS, the computer will baseline the TPS reading when you start the car. So if your TPS reads .94, the computer will treat that as "0" and do all the math from there.
Now, if you want to test if your TPS is working right, then you should test it. Your average DMM (digital multimeter) will do fine, as long as it has a setting for 12v. You stick a pin through the wire you want to test; touch the positive wire to the pin and the other end to a good ground. You can use the green bolt next to the hood prop rod.
