Code P1244 1999 Ford F150 Description
The P1244 diagnostic trouble code (DTC) for a 1999 Ford F150 indicates that the alternator load input has failed high. This means that the Engine Control Module (ECM) has detected a higher than normal 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. When the ECM detects a high voltage signal, it can affect the vehicle's performance and potentially lead to various issues.
Common Causes of P1244 1999 Ford F150
- Faulty alternator
- Damaged wiring or connectors in the alternator load input circuit
- Malfunctioning ECM
- Overloaded electrical system
- Corrosion or poor connections in the electrical system
