Code P163D Lincoln Description
The P163D diagnostic trouble code for Lincoln vehicles indicates a problem with the Secondary Generator Field Terminal Circuit being too high. This code is typically associated with the vehicle's charging system, specifically the alternator. The alternator is responsible for generating electricity to power the vehicle's electrical systems and recharge the battery while the engine is running. The Field Terminal Circuit controls the amount of electrical output from the alternator to meet the vehicle's electrical demands.
Common Causes of P163D Lincoln
- Faulty alternator
- Loose or corroded wiring connections
- Faulty voltage regulator
- Short circuit in the Field Terminal Circuit
- Electrical system overload
Symptoms of P163D Lincoln
- Dimming or flickering lights
- Battery warning light illuminated on the dashboard
- Difficulty starting the vehicle
- Electrical components not functioning properly
- Overheating of the alternator
How to Fix P163D Lincoln
- Perform a visual inspection of the wiring connections to the alternator and battery to check for any loose or corroded connections.
- Test the alternator's output voltage to determine if it is within the manufacturer's specifications.
- Check the voltage regulator for proper functioning and replace if necessary.
- Test the Field Terminal Circuit for continuity and repair any shorts or open circuits.
- Clear the diagnostic trouble code from the vehicle's computer system and retest to ensure the issue has been resolved.
Cost to Fix P163D Lincoln
The cost of repairing a P163D code can vary depending on the underlying cause of the issue. In general, replacing a faulty alternator can cost between $300 and $800, including parts and labor.
