Fuel Pressure Regulator 1 Control Circuit High
The P0092 code means that the fuel pressure has fallen outside the range of acceptable pressures set by your 2009 Saturn Vue 's manufacturer. Once the Engine Control Module (ECM) picks up the signal from the fuel pressure regulator that the fuel pressure is incorrect, the Check Engine Light will be illuminated.
P0092 could be caused by a faulty part of the fuel system including:
A visual inspection of the system in question is always the best place to start with any diagnosis. If any obvious damages are found, it would be wise to repair them before continuing the diagnostic process. Once all visual damages have been repaired, testing of sensors and the fuel pressure would follow. The integrity of the fuel system sensors and the fuel pressure reading taken will determine how to proceed with this diagnosis.
Not following all of the proper diagnostic steps to ensure that the correct part is being replaced
Not making sure that the fuel level and fuel pressure are noted before replacing any parts (both readings aid in the diagnosis)
Given that this code can affect a 2009 Saturn Vue 's performance in a major way, it can be considered quite serious. Complications related to this code can cause a 2009 Saturn Vue to die, or not have enough power to get anywhere, potentially leaving a driver stranded on the side of the road.
Be sure that the diagnostic process is carried out in full. Any part of the fuel system that gets skipped over during the diagnostic is a potential cause of misdiagnosis. It is very important to consider every part of the fuel system when trying to find the source of this problem.
