TPS is a 5 volt sensor, you can use a sewing needle to pierce wires to test voltages while sensors are hooked up
Key on, the 5v comes from computer
Test upper wire(Grey/red), should be 5v, 4.8-5.1
Test center wire, .69-.99v, under 1volt
Open throttle manually while testing center wire, voltage should ramp up, NO jumps or drops, and get to at least 4.5v when Wide Open Throttle(WOT) is reached
FYI on newer OBD2 vehicles, TPS sensor will show 17% to 19% when throttle is closed, why?
Shouldn't it be 0%, no, its a 5volt range, 0v to 5v, when throttle is closed TPS is just under 1volt, so just under 20%
And WOT won't be 100%, maybe 90%
