To test the throttle position sensor (TPS) on a 1991 Chevy S10, you'll need a multimeter. First, locate the TPS on the throttle body and disconnect the electrical connector. With the multimeter set to measure voltage, probe the middle terminal of the TPS while slowly moving the throttle from closed to wide open; you should see a smooth increase in voltage. If the voltage is erratic or doesn't change appropriately, the TPS may be faulty and should be replaced.
