Throttle Position (TP) Sensor
WARNING: This page is about a different car, the 1995 Ford RV Cutaway, 1995 Ford Econoline, 1995 Ford Cutaway, and 1995 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.
Mounted on throttle body at throttle plate rod, TP sensor monitors throttle plate opening. The TP sensor signal to PCM is proportional to throttle opening angle. The TP sensor signal affects air/fuel ratio, injector timing, idle speed, EGR flow and fuel pressure.
