Vehicle Speed Sensor (VSS)

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1995 Ford RV Cutaway, 1995 Ford Pickup, 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.

Disconnect VSS electrical connector. Using DVOM, measure resistance across sensor terminals. Resistance should be 190-250 ohms. Replace sensor if not within specification. Faults in VSS sensor or circuit should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (5.8L) article. If no diagnostic trouble code has been set, see CIRCUIT TEST DP in the appropriate TESTS W/CODES - EEC-IV (5.8L) article for additional sensor testing and specifications.
