Does your 1999 Ford Explorer have a fuel tank pressure sensor?

1999 Ford Explorers did not have a fuel tank pressure sensor in the same way modern vehicles do. Modern fuel tank pressure sensors are part of the evaporative emission control system (EVAP) and monitor pressure to detect leaks. While the 1999 Explorer had an EVAP system, it used different methods to detect leaks, primarily relying on a purge valve and monitoring vacuum in the system rather than directly measuring pressure with a sensor.
