Code P1245 2006 Ford Fusion Description
The P1245 diagnostic trouble code (DTC) for a 2006 Ford Fusion indicates that the alternator load input has failed low. This means that the vehicle's powertrain control module (PCM) has detected a lower than expected voltage signal from the alternator load input circuit. The alternator load input is responsible for monitoring the electrical load on the vehicle's charging system, including the battery and other electrical components. When the voltage signal is lower than expected, it can lead to issues with the vehicle's charging system, potentially causing the battery to not receive enough charge or leading to electrical system malfunctions.
Common Causes of P1245 2006 Ford Fusion
- Faulty alternator
- Damaged wiring or connectors in the alternator load input circuit
- Malfunctioning PCM
- Issues with other components in the charging system, such as the battery or voltage regulator
Symptoms of P1245 2006 Ford Fusion
- Dim or flickering headlights
- Difficulty starting the vehicle
- Dashboard warning lights related to the charging system
