How do you adjust 305 tbi TPS?

To adjust the throttle position sensor (TPS) on a 305 TBI (Throttle Body Injection), first, locate the TPS on the throttle body. Use a multimeter to measure the voltage output at the sensor's middle pin while slowly opening the throttle plate. The voltage should typically range from about 0.5 to 0.8 volts at closed throttle and increase smoothly to around 4.5 volts at wide open throttle. If necessary, loosen the TPS mounting screws and adjust the sensor position to achieve the correct voltage readings, then retighten the screws.
