The P1246 code in your 2022 Ford Maverick indicates a malfunction in the generator (alternator) field circuit. This Ford-specific code signals issues with the circuit that controls the alternator's output.
Understanding Generator Field Circuit
The field circuit controls the alternator's magnetic field, which determines charging output. The PCM modulates this circuit to maintain proper system voltage. P1246 indicates this control has failed.
Common Causes of P1246
- Alternator internal failure
- Field circuit wiring damage
- PCM control circuit failure
- Poor electrical connections
- Battery sensor issues affecting control
- Voltage regulator malfunction
Symptoms of Field Circuit Issues
- Check engine light on
- Battery warning light
- Overcharging or undercharging
- Battery draining
- Electrical system problems
- Dim or bright lights
Maverick Hybrid Considerations
The Maverick is available as a hybrid. On hybrid models, the charging system is different. P1246 is more relevant to conventional Maverick models with traditional alternators.
