Fuel Pressure

WARNING: This page is about a different car, the 2008 Chrysler PT Cruiser. 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 or a pinched fuel supply. 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.
