Q: What does code P1574 mean?

Throttle Position Sensor Disagreement Between Sensors. P1574 on Ford vehicles means the powertrain control module (PCM) has detected a disagreement between the signals from two throttle position sensors that should track together. The PCM compares the two voltages and sets this code when the difference exceeds a calibrated threshold for a set time, indicating a faulty sensor, wiring issue, or mechanical problem in the throttle body.
