P2503: The Low Pressure Fuel System Sensor Circuit Malfunction
The P2503 code is related to the charging system of an automobile. It is set by the Powertrain Control Module (PCM) when the output voltage is not within the factory specifications. This code indicates that the charging system voltage is low.
The PCM monitors the charging system for any changes in the output voltage. If the voltage is not within the specified range, the P2503 code is set.
It is important to address this issue promptly to avoid any further damage to the vehicle’s electrical system.
FAQ
If you see the engine light or service engine soon warning light on your dashboard, it could be due to the P2503 fault code. This code is usually caused by a faulty generator (alternator), an open or shorted generator harness, poor electrical connection in the generator circuit, or a faulty Powertrain Control Module (PCM). To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P2503 fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few things you can do to identify the issue. The cause of this fault code could be a faulty generator (alternator), an open or shorted generator harness, a poor electrical connection in the generator circuit, or a faulty powertrain control module (PCM). To fix the issue, you should check the possible causes listed above and visually inspect the related wiring harness and connectors.
