This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's a problem with the electricity that the generator (or alternator) is making.
The vehicle's control module has detected an issue with the electrical output from the generator.
The P325A code indicates that the vehicle's powertrain control module (PCM) has identified a discrepancy in the electrical output from the generator (alternator). This could be due to a fault in the generator itself, the wiring, or the control module's ability to read the generator's output.
• Battery warning light on the dashboard
• Dimming headlights
• Electrical accessories not functioning properly
• Faulty generator/alternator
• Damaged or corroded wiring or connectors
• Faulty powertrain control module (PCM)
Generator: Another term for alternator, which charges the car's battery.
PCM: Powertrain Control Module, the computer that controls engine and transmission functions.
• Check the battery and charging system voltage.
• Inspect the generator/alternator for physical damage.
• Examine wiring and connectors for damage or corrosion.
• Replace the generator/alternator if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly check battery and alternator health.
• Ensure all electrical connections are clean and secure.
• Have the charging system inspected during routine maintenance.
Electrical System Issue
• Have your vehicle inspected by a professional if you see the battery warning light.
• Avoid using electrical accessories until the issue is resolved.
Check with your vehicle manufacturer for specific warranty coverage related to the electrical system.
This code has been associated with issues in vehicles with high mileage or those that have experienced electrical system failures.
Moderate – It's important to address this issue to avoid being stranded with a dead battery.
Driving with a failing alternator can lead to a loss of power and is not safe. Address this issue promptly.
• Engine running
• Electrical load applied (e.g., headlights on)
The generator/alternator is typically located at the front of the engine and is driven by the engine's serpentine belt.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to a dead battery and the car not starting.
Q: Can I drive with this code?
A: It's not recommended to drive for long periods with this code, as it can lead to a complete loss of electrical power.
