Fuel Shutoff Valve âAâ Control Circuit/Open
P0005 is a generic type of of diagnostic trouble code which indicates that the Engine Control Module (ECM) detects a problem with the fuel pump shut off solenoid. This code is rarely seen as it does not pertain to any particular make or model of 2009 Saturn Vue .
The fuel pump shut off solenoid is an electromagnetic switch that allows or blocks the passage of fuel from the fuel pump to the engine, according to the position of the ignition switch. When the ignition switch is turned with the ignition key, a signal is sent to the fuel pump shut off solenoid, which protrudes or retracts a shaft that starts or stops the flow of fuel to the engine accordingly. The shaft pops out within the fuel passage to block the flow of fuel if the ignition is off, or the switch is defective.
Tests the ignition switch and fuel pump shut off solenoid with a multimeter to ensure they have the proper ground, voltage reference, and resistance levels
Compares the results of these tests to the specifications of the manufacturer
Inspects the wires and terminals of the Engine Control Module for corrosion and fraying
Checks the fuel pump pressure
Many mechanics believe that the issue with a fuel pump shut off solenoid trouble code is always within the fuel pump, so they replace the entire fuel pump. Oftentimes, the actual issue with this code is external and you can get away with just replacing the solenoid itself.
Not tremendously serious, though a stall or a no start experience is likely. This may be dangerous depending on when and where the stall of your 2009 Saturn Vue occurs.
It is suggested to verify whether the fuel pump shut off solenoid issue is external to the fuel pump, or internal. Doing so will save both time and money.
