Question about Ford Ranger
You will need a ohm meter with resistance setting, there are three wires that go to the tps sensor, one is ground the other is five volts and the last is the signal wire, use the meter to locate the 5volt wire and then the ground wire and the last will be the signal wire, thats the wire to use, it sounds like you have done this already but at idle 1.0 is good and 4.99 to 5.0 is good at full throtle. what you do is check the throtle slowly and check for dead spots as you move the gas pedal, the problem is that the dead spot may be so fast you wont see it, a lab scope would be the ideal tool to use but try the meter, im not sure what your problem is but this is how to test the tps.
