Your car is equipped with a lot of systems and components that work together to keep your vehicle running. Some of these components may malfunction at one point. Thankfully, modern vehicles are equipped with on-board diagnostic (OBD) systems that help you identify if something is wrong with your vehicle.
Did your scan tool read a P0007 code? Read on to learn what it means.
What Does the P0007 Code Mean?
Diagnostic Trouble Code (DTC) P0007 stands for “Fuel Shutoff Valve “A” Control Circuit High.” It is triggered when the powertrain control module (PCM) perceives a problem with the fuel shutoff valve or its circuit.
The code P0007 indicates a potential problem with the shutoff solenoid or its electrical circuit. P0007 is very rare. Read our note about P0007, other related codes and the fuel shutoff solenoid.
Note: The definition of each code may vary depending on the vehicle manufacturer. We recommend checking your trusted repair manual or repair database for the exact code definition.
More on the Fuel Shutoff Solenoid
The basic function of a fuel shut-off solenoid is to electrically shut off fuel supply to the high-pressure fuel injection pump. This solenoid may be connected to the pump via a lever.
Usually mounted at the side of the pump, the fuel shutoff solenoid controls the starting and stopping of the engine, regardless of the accelerator pedal position.
In order for the solenoid to function properly, it needs high and low amperage currents. For example, when the ignition is off, the spring loaded plunger must be in the down position. This blocks the flow of fuel to the pump. However, once the power is cranked, it automatically sends the plunger in the up position, allowing the flow of fuel to the pump.
Once the PCM detects that there is a potential problem with the solenoid or its circuit, it may trigger error code P0007.
What are the Possible Causes of the P0007 Code?
Here are the possible triggers of the P0007 code:
- Faulty fuel shut off solenoid/valve
- Malfunctioning fuel shut off relay
- Fault in the fuel shut off solenoid circuit
- Malfunctioning PCM
What are the Common Symptoms of the P0007 Code?
Here are the common symptoms you should watch for that may be related to this trouble code:
- Check engine light is on
- Decreased engine performance
- Decreased fuel economy
- Engine won’t start
How to Diagnose the P0007 Code
Diagnosing code P0007 can be challenging. Because of its various possible triggers, it may be hard to pinpoint its exact underlying cause.
If you’re not knowledgeable in auto repair, it is best to leave the job to a professional. However, if you would like to diagnose this code yourself, we recommend consulting a repair manual or a repair database for proper diagnostic procedures.
How to Fix the P0007 Code
Although P0007 is a generic code, its exact diagnosis and repair procedures may vary depending on your vehicle’s year, make, and model. For example, repair procedures for a P0007 in a Dodge may vary from a P0007 in a Hyundai.
If you’re a skilled automotive DIYer and you would want to fix this code yourself, research confirmed solutions that are specific to your car’s year, make, and model. Consult online auto repair resources and guides. You may also secure an automotive repair subscription service for more information.
