This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the part that controls how much fuel goes into the engine. It's like the fuel tap isn't working right.
The P2372 code is triggered when the Engine Control Module (ECM) detects a low voltage or problem in the control circuit of the fuel volume regulator B.
The fuel volume regulator is responsible for controlling the amount of fuel that is delivered to the engine. This code indicates that there is a low voltage condition in the control circuit for the fuel volume regulator B, which could be due to a wiring issue, a faulty regulator, or a problem with the ECM.
• Check Engine Light is on
• Poor engine performance
• Engine stalling or hesitation
• Faulty fuel volume regulator B
• Wiring issues in the control circuit
• Faulty ECM (Engine Control Module)
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the fuel volume regulator B for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the fuel volume regulator B if faulty.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance checks
• Ensure fuel system components are clean
• Inspect wiring for wear and tear
Engine Performance
• Avoid driving long distances until repaired.
• Have the vehicle inspected by a professional mechanic.
Check with your vehicle manufacturer for warranty coverage on the fuel system components.
This code has been reported in various vehicles with fuel system issues, often related to wiring problems.
Moderate – It should be addressed soon to prevent further engine performance issues.
Ignoring this code can lead to increased emissions and reduced fuel efficiency, which may not comply with local regulations.
• Engine running
• Warm engine temperature
The fuel volume regulator is typically located near the fuel rail or fuel pump.
Q: Can I drive with a P2372 code?
A: It's not recommended as it can lead to poor engine performance and increased emissions.
Q: How can I reset the P2372 code?
A: You can clear the code using an OBD-II scanner, but it's important to fix the underlying issue first.
