Throttle Position (TP) Sensor
WARNING: This page is about a different car, the 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.
Faults in TP sensor or circuit should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (3.0L) article. If no diagnostic trouble code has been set, see CIRCUIT TEST DH in TESTS W/CODES - EEC-IV (3.0L) article for additional sensor testing and specifications. Ensure none of following conditions exist:
- Binding throttle linkage.
- TP sensor loose or not seated properly.
- Throttle plate not fully closed.
