This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble talking to the part that controls how alternative fuel is used. It's like when a light switch doesn't work because the wires are not connected properly.
The P25BE code indicates an issue with the circuit that controls the disable function of the alternative fuel system. This could be due to an open circuit or a fault in the wiring or connectors.
The P25BE code is triggered when the Powertrain Control Module (PCM) detects an open circuit or malfunction in the alternative fuel disable control circuit. This circuit is responsible for enabling or disabling the alternative fuel system when necessary. An open circuit can prevent the proper operation of the alternative fuel system, leading to potential performance issues or emissions problems.
• Check Engine Light is on
• Reduced fuel efficiency
• Inability to switch to alternative fuel mode
• Faulty wiring or connectors in the alternative fuel disable control circuit
• Failed alternative fuel control module
• Blown fuse related to the alternative fuel system
PCM: Powertrain Control Module
Circuit: A complete path that allows electricity to flow
• Use an OBD-II scanner to confirm the P25BE code.
• Inspect the wiring and connectors of the alternative fuel disable control circuit for damage or disconnection.
• Test the alternative fuel control module for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the alternative fuel control module if faulty.
• Check and replace any blown fuses related to the system.
• OBD-II scanner
• Multimeter
• Wire repair tools

Moderate
• Chevrolet Volt
• Toyota Prius
• Ford Fusion Hybrid
• Regularly inspect and maintain the vehicle's wiring and connectors.
• Keep the alternative fuel system components clean and free of debris.
• Follow the manufacturer's maintenance schedule for the alternative fuel system.
Circuit Issue
• Avoid using alternative fuel mode until the issue is resolved.
• Consult a professional mechanic for a thorough diagnosis.
Repairs may be covered under the vehicle's emissions warranty. Check with the manufacturer.
This code is relatively uncommon and typically associated with vehicles equipped with alternative fuel systems. It has been reported more frequently as these systems become more prevalent.
Moderate – The vehicle can still operate, but fuel efficiency may be reduced, and emissions could be affected.
Operating a vehicle with this code may lead to increased emissions, which could violate local environmental regulations.
• Vehicle in alternative fuel mode
• Engine running
The alternative fuel control module is typically located near the engine or fuel system components.
Q: Can I drive my car with the P25BE code?
A: Yes, but it's best to get it fixed soon to avoid reduced fuel efficiency and potential emissions issues.
Q: What fuels are considered alternative fuels?
A: Alternative fuels include options like electricity, hydrogen, ethanol, and natural gas.
