Fuel Pressure

WARNING: This page is about a different car, the 2005 Dodge Magnum and 2005 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The fuel pressure regulator controls fuel system pressure. The PCM cannot detect a clogged fuel pump inlet filter, clogged in-line fuel filter, or a pinched fuel supply or return line. However, these could result in a rich or lean condition causing the PCM to store an oxygen sensor, fuel system, or misfire diagnostic trouble code.
