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 electrical connection to the part that helps charge the car's battery. It's like when a toy's battery isn't charging because the wires aren't connected properly.
The P0625 code indicates that the vehicle's Powertrain Control Module (PCM) has detected a low voltage or open circuit condition in the generator field control circuit.
The generator field control circuit is responsible for regulating the voltage output of the alternator. When the PCM detects that the voltage in this circuit is lower than expected, it triggers the P0625 code. This could be due to a poor electrical connection, a faulty alternator, or issues with the wiring harness.
• Battery warning light on the dashboard
• Dimming headlights
• Battery not charging properly
• Faulty alternator
• Poor electrical connection
• Damaged wiring harness
PCM: Powertrain Control Module
Alternator: A device that generates electrical power for the vehicle and charges the battery.
• Check the battery and alternator connections.
• Inspect the wiring harness for damage.
• Test the alternator output voltage.
• Repair or replace damaged wiring.
• Replace the alternator if faulty.
• Ensure all electrical connections are secure.
• Multimeter
• Wrench set
• Screwdriver

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check battery and alternator connections.
• Inspect wiring for wear and tear.
• Ensure battery terminals are clean.
Electrical Issue
• Avoid using high electrical load devices until repaired.
• Monitor battery voltage regularly.
• Seek professional diagnosis if unsure.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been associated with alternator and battery issues in vehicles for many years.
Moderate – While the vehicle may still operate, it can lead to battery drain and potential breakdown.
Driving with a malfunctioning charging system can lead to vehicle breakdown and should be addressed promptly.
• Engine running
• Electrical loads applied
The alternator is typically located at the front of the engine, driven by the serpentine belt.
Q: What does the P0625 code mean?
A: It means there's a low voltage issue in the alternator's field control circuit.
Q: Can I drive with a P0625 code?
A: It's not recommended as it can lead to battery failure and vehicle breakdown.
