2007 Ford ranger evap check: vent valve commanded closed 100%. Vapor management valve closed (off). Fuel tank pressure is negative -0.27 psi. Note fuel tank pressure sensor drops to 1.57 volts. Computer is now watching how quick the negative psi drops and if fails test check engine light will come on.
