Diagnostic trouble code (DTC) P0004 code stands for “Fuel Volume Regulator Control Circuit High.” This code indicates that the vehicle’s computer (also known as the powertrain control module or the PCM) has detected that the electrical reading in the fuel volume regulator control circuit is above the expected value.

What does fuel volume regulator control circuit low mean?
The fuel volume regulator control circuit low code may have several causes: Possible corrosion in the sensor connector. A short in the sensor wiring to the ECM. A defective fuel pressure regulator. The ECM is damaged.
Where is the fuel volume control?
Fuel pressure and volume are regulated by control valves located on the pump. The fuel volume control valve (otherwise known as a fuel volume control regulator) regulates the volume of fuel produced by the injection pump. The fuel volume control valve (FVCV) is controlled by a solenoid.
What is fuel volume regulator control?
The role of the FVCV is to regulate the fuel volume that comes from the injection pump. Controlled by a solenoid, the PCM can turn the valves on and off, allowing fuel injectors to get enough fuel. A fuel pressure sensor monitors the performance of your vehicle’s FVCV.
How do I fix error code P0001?
- Connect a professional scan tool.
- Check for any other faults.
- Analyze data from the ECM.
- Road test the vehicle.
- Check to see if the P0001 returns.
- Inspect all of the items listed above.
- Further diagnose the problem with the equipment listed above (scan tool, voltage meter).
What does P0001 mean?
What does control circuit high mean?
This often means that the malfunction is in a certain area of the system, as opposed to any one component or circuit. Usually, the P0629 code is caused by a defective fuel pump, or a problem with the fuel pump relay. Other causes include: Bad connectors, or shorted or open wiring in the CAN bus harness.
What can cause a P0004 code?
- Possible corrosion in the sensor connector.
- A broken wire to the ECM.
- A defective fuel shutoff valve.
- The ECM is damaged.
What is P0002 mean?
What the P0002 code means. P0002 is a generic OBD-II code indicating an issue with the engine control module (ECM) reading signals from your fuel pressure regulator on your fuel injection rail mounted to your engine.
What does a fuel rail pressure sensor do?
It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the computer, which then uses it to make adjustments to the vehicle’s fuel and timing. When the sensor has an issue it can cause problems with the performance of the vehicle.
What is a generic car code?
Generic and manufacturer specific codes Codes starting with 0 as the first digit are generic or global codes. It means that they are adopted by all cars that follow the OBD2 standard. These codes are common enough across most manufacturers so that a common code and fault message could be assigned.
Can I drive with P0599?
While the vehicle may show no symptoms at all when the P0599 code is stored, this code does represent a serious issue that could lead to major drivability issues later. A vehicle with this code stored in the PCM should be repaired as soon as possible.
What does shift solenoid A control circuit high mean?
Low transmission fluid. Dirty or contaminated transmission fluid. Damaged or defective wiring.
What is a thermostat heater control circuit high?
Diagnostic trouble code (DTC) P0599 stands for “Thermostat Heater Control Circuit High.” This code is logged when the powertrain control module (PCM) detects an incorrect signal from the thermostat. Some vehicles with newer engines can utilize thermostats that are electronically controlled by the PCM.
What causes P0002 code?
The P0002 code is defined as Fuel Volume Regulator Control Circuit Range/Performance. It is set by the PCM whenever it perceives a problem with the fuel volume regulator (fuel volume control valve) or its circuit. Unlike other common codes, it’s rare for vehicles to get a P0002 code.
How do I fix code P0090?
- Repair of an open or short in the wiring harness.
- ECU replacement if it fails test procedures.
- Replacement of the fuel pressure regulator.
- Fixing poor electrical connections.
What are the symptoms of a faulty fuel pressure sensor?
- #1 – Check Engine Light.
- #2 – Difficulty Starting Engine.
- #3 – Weak Acceleration.
- #4 – Stalling.
- #5 – Bad Fuel Mileage.
Where is the fuel rail pressure sensor located?
Your truck’s fuel rail pressure sensor is located near the center of the fuel rail and is linked to the central computer of your vehicle (the ECU). You’ll need to open your hood and find the fuel injectors at the head of the engine near the intake manifold.
How do you test a fuel rail pressure sensor?
How do you reset a car code without a scanner?
Where can I read car codes for free?
If you have a problem with your car and you don’t know what it is, most auto part stores (such as AutoZone, Pep Boys and Advance Auto Parts) will provide a free diagnostic code reading. It is also called an OBD reading.
How do I permanently delete a DTC code?
The only way to clear a PDTC is to fix the underlying problem with the vehicle that originally caused the PDTC and its corresponding DTC to set, and then allow the vehicle sufficient drive time to re-run the monitor that identified the problem in the first place.
Can I replace transmission solenoid myself?
Replacing a transmission shift solenoid can be done by most any auto repair shop, automobile dealership service center or you can do-it-yourself “DIY”.
How much does it cost to fix a shift solenoid?
Shift Solenoid Repair and Replacement Cost The overall cost to replace the shift solenoid in an automatic transmission ranges from $200 to $500 for a single solenoid. If the damage requires you to replace the entire solenoid pack the cost increases to between $250 and $700.
How do you reset a transmission solenoid?
After turning on the car, you must shift through the automatic transmission gear at least two times. In manual cars, shifting between drive and reverse should occur three times. The gear shifting must continue for at least 10 miles, and automatically reset the transmission control module.
