An OBD-II code warns you about the possible issues your car may have. To successfully resolve these issues, you need to know what the logged code means. If you’re having trouble figuring out what code P0005 means and how to fix it, you’ve come to the right place. Read on to learn more about P0005, what triggers it, and the symptoms you should look out for.

What Does the P0005 Code Mean?

Diagnostic trouble code (DTC) P0005 stands for “Fuel Shutoff Valve A Control Circuit/Open.” This code refers to an issue in the fuel shutoff valve control, usually indicating a potential open circuit within the electric system. The code gets logged when the powertrain control module (PCM) detects a problem with the fuel pump shutoff valve.

The fuel shutoff valve controls the passage of fuel to the engine, depending on the position of the ignition switch. When this switch turns, the fuel shutoff solenoid protrudes or retracts a shaft that controls the flow of fuel to the engine. If the ignition is off or the switch is faulty, the shaft pops out within the fuel passage to block the fuel flow.

Circuit Open means that there’s a lack of continuity somewhere in the fuel shutoff valve circuit. Causes of open circuits vary, though this type of code could stem from broken wiring, poor connections across electrical connectors or previously repaired wiring, loss of ground that prevents current flow, blown fuses, defective relays, faulty switches, and any other issue that could prevent the flow of the current through the wiring.

This specific code rarely gets used by vehicle manufacturers, so if P0005 engine code appears, make sure you are using the correct diagnostic interface for your car.

P0005 is a common issue among the following makes: Subaru, Mitsubishi, Chevrolet, Dodge, and Hino.

Note: The definition of code P0005 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Possible Causes of the P0005 Code?

P0005 is a generic code, so it can have several triggers. Here are the most common causes:

  • Failed fuel shutoff valve
  • Faulty fuel shutoff valve relay
  • Powertrain Control Module (PCM) failure
  • Circuit issues, such as damaged wiring or poor connections

What are the Common Symptoms of the P0005 Code?

Depending on the severity of the issue, the PCM may also store other related diagnostic trouble codes. For engine code P0005, it can appear alongside P0006 and P0007. Generally, you may notice the following symptoms if your vehicle stored a P0005 trouble code:

  • Vehicle will not start
  • Poor engine performance
  • Stalling engine
  • Check engine light on
check engine light is on 3 3
An illuminated check engine light is a common symptom of error code P0005.

How to Diagnose the P0005 Code

Diagnosing code P0005 can be difficult, as it has many possible causes. Aside from having a variety of triggers, it is a code rarely used by manufacturers, so there might not be enough information about this code.

As this is a rarely seen trouble code, it is best to refer to your manufacturer’s repair information for diagnostic instructions. Bear in mind that diagnostic and repair strategies may vary and largely depend on your vehicle’s make and model. If you’re not a seasoned auto repair DIYer, it is best to leave this job to the experts.

How to Fix the P0005 Code

Similar to most OBD-II codes, there is no set solution for a P0005 code. Although code P0005 shares similar triggers and symptoms with various other engine codes, this does not mean that it can be fixed with a generic solution. Repair and diagnostic steps still depend on the specifications of your vehicle. A P0005 code on a Chevy may require a different repair method from that of a P0005 on a Honda.

If you’re not familiar with auto repair, leave the repairs to an expert. However, if you’re a skilled automotive DIYer and want to do the repairs yourself, there are online auto repair sources you can consult to help you identify which repair steps apply to your vehicle.

For instance, an ALLDATA subscription provides detailed factory repair information that you can use to resolve the DTC issues in your car. This should help you fix error code P0005 and serve as a reference for future problems you may encounter.
