How do I Adjust the Throttle Position Sensor on a 1993 Ford Mustang 302?
The 1993 Ford Mustang equipped with a 302 (5.0 liter) engine uses a throttle position sensor (TPS) to signal the on-board computer how far the driver is pressing the throttle pedal. The computer uses this information along with air flow and vehicle speed to adjust the fuel and ignition systems according to this engine load. The TPS itself is a potentiometer and has a varying resistance through its travel. By supplying a 5-volt reference voltage and measuring the amount of voltage the TPS returns to the computer, the computer can calculate throttle position.
