    Yeah your computer wants to know when your throttle is at rest and when it begins to open. This will effect driveability for thing like really light cruise.

      should I leave it if its fine or will it blow up my engine one day? Drives the same as it did before but with noticeably improved acceleration. There's probably a mechanic gen but I didn't find anything on the catalog.

        if your TPS is set too far one way, when you cruise with super light acceleration it might suddenly cut fuel of an on again, rather than smoothly transitioning to idle.
        If your TPS is set too face the other way your car won't go into proper idle mode when you're idling - the ECU won't do all the things it usually does for idle speed and timing and AFR, it will act like you're still accelerating slightly.

            WRONG
            OP's TPS specifically has a circuit which closes to tell the ECU when the throttle has returned to it's resting position. The ECU cannot "relearn" itself to make that circuit close if it not mechanically adjusted to close.

            wow, you're correct on exactly one position of out thousands of positions (the closed position). meanwhile the ecu will learn all the other positions on its own based on maf/map and crank acceleration.

          You will also say your car will runs fine after I unbolt your o2 sensor, that doesn't prove it's the way it should be, nor does it prove the blanking plate I used to replace your o2 sensor is a "bolt on part".

      Nothing you do with a multimeter will affect the sensor or how the car reads the sensor, as it is just a potentiometer that reads how much the throttle shaft twists.

            Yeah, it's better to not overcomplicate things to people that don't know about them. A TPS is not a magic destruction button if it's not meticulously calibrated, if it gores in and works, then it will not cause problems. At worst you lose a percent or two off the top, but it's not going to matter in a fricking geo tracker.

        If by adjustment you mean clocking it to the key on the throttle shaft so there is no play before it engages the sensor, sure, pretending it's a complicated procedure that only a ~~*trained professional*~~ is allowed to understand is moronic, Moshim.

    What car? That looks like a 90s Subaru TPS, which requires adjustment. All you do is backprobe the center pin while in KOEO (key on engine off), and with the screws loosened just enough to be able to adjust the sensor, slowly move it until the multimeter reads within ±0.05V of 5 volts, preferably as close to exactly 5 volts as possible, then tighten the screws. Very easy.
