[SOLVED] P2504 Code: High Charging Voltage – How To Fix

The P2504 fault code in automobiles indicates a problem with the generator or alternator. The most common symptom is the illumination of the engine light or service engine soon warning light. The cause of this fault code could be a faulty generator, an open or shorted generator harness, poor electrical connection in the generator circuit, or a faulty Powertrain Control Module (PCM).

The importance of repairing this issue lies in the fact that the alternator is responsible for charging the battery and powering the electrical system. The difficulty level of repairing this issue is moderate, with a repair time of 1.0. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
