This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that controls the flow of fuel. It's like a switch that lets fuel go to the engine, and this switch isn't working right.
The engine control module (ECM) has detected an issue with the circuit that controls the fuel shutoff valve B, indicating an open circuit or a fault.
The P2665 code is triggered when the ECM detects an open circuit condition in the fuel shutoff valve B control circuit. This could be due to a wiring issue, a faulty valve, or a problem with the ECM itself. The fuel shutoff valve is responsible for controlling the flow of fuel to the engine, and an open circuit means the valve may not be operating as expected.
• Check Engine Light is on
• Engine may not start
• Poor engine performance
• Faulty fuel shutoff valve B
• Open or shorted wiring in the control circuit
• Faulty ECM
ECM: Engine Control Module

• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the fuel shutoff valve B for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty fuel shutoff valve B.
• Replace or reprogram the ECM if necessary.
• OBD-II scanner

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regular maintenance checks on wiring and connectors.
• Ensure proper fuel system maintenance.
• Use quality fuel to prevent clogging and damage.
Fuel System Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult a professional mechanic for a thorough diagnosis.
Check your vehicle's warranty to see if fuel system components are covered.
The P2665 code has been reported in various models, often related to wiring issues or faulty valves.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Ignoring this code could lead to safety issues if the engine stalls unexpectedly.
• Engine running
• Fuel system pressurized
The fuel shutoff valve is typically located near the fuel rail or fuel tank.
Q: Can I drive with a P2665 code?
A: It's not recommended to drive with this code as it could lead to engine performance issues.
Q: How do I reset the P2665 code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is fixed first.
