Known issues on the 2003 Seville. One recall is on federal record for this model year, covering the fuel tank assembly: the fuel tank pressure sensor is unusually susceptible to malfunction, and a failed sensor can apply excessive vacuum during self-diagnostic testing, damaging fuel system components and allowing fuel to leak when the vehicle is refueled, which can ignite and result in a fire. Owners have filed 27 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind that fuel system are here.
Whether you're inspecting the fuel tank pressure sensor or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2003 Seville.
