I have 5v stuck on my middle signal wire (which references throttle all the way open?) I am trying to calibrate it by using a multimeter. One on earth and one on signal but I cant because It is stuck on 5v. It is the middle wire. The one next to it is a ground and other side is constant 5v. Any suggestions? I have tried another sensor with same result

Disconnect the TPS from the loom and check the resistance from that centre wire to either side with multimeter as you open and close the throttle. If it does not change resistance then it is probably faulty. If it changes resistance it is probably working, and would point to a wiring fault (ie, signal wire & power wire shorted together somewhere in the loom).

Repeat test with spare TPS to reassure yourself.

    • Just cut the bottom of the guard out. It's no longer got a big duct, to a sealed box, or a restriction. It has all the cold air from outside. Also, that cai you showed looks terrible. Bends are NOT good for go gos!
    • Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 🤔
    • If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.
    • And we shall have to presume that Canada is the same?
    • In the US almost everything is E10. It can't exceed 10% by much or fuel systems have trouble adapting. At the same time because MTBE, MMT, and TEL are all banned they need as much ethanol in it as possible to boost octane.
