In this article, we will go through the 2012 Dodge Charger fuel pump wiring diagram to help you understand how it works and troubleshoot any problems that you may encounter.
What is a Fuel Pump Wiring Diagram?
A fuel pump wiring diagram is a schematic representation of the electrical system that powers the fuel pump. It shows the wiring connections between the fuel pump, the fuel pump relay, the battery, and other components in the circuit. This diagram can help you understand how the electrical system works and where to troubleshoot if there is a problem.
In the 2012 Dodge Charger, the fuel pump wiring diagram is essential for diagnosing and repairing any electrical issues with the fuel pump system. It is also helpful in installing a new fuel pump or replacing any components in the system.
The Fuel Pump Wiring Diagram for the 2012 Dodge Charger
The 2012 Dodge Charger fuel pump wiring diagram is fairly straightforward. The diagram shows the connections between the fuel pump relay, the battery, and the fuel pump. It also shows the fuse that protects the fuel pump circuit and the wiring connections for the fuel pump sender unit.
| Fuel Pump Relay | Battery | Fuel Pump |
|---|---|---|
| Pin 30 – Fuse Power | Positive (+) Terminal | Fuel Pump Power |
| Pin 85 – Ground | N/A | N/A |
| Pin 86 – Relay Control | Automatic Shut Down Relay (ASD) | N/A |
| Pin 87 – Power to Fuel Pump | N/A | Fuel Pump Ground |
The fuel pump relay is controlled by the ASD relay. When the key is turned on, the ASD relay sends power to the fuel pump relay, which then sends power to the fuel pump. The fuel pump relay also sends power to the fuel pump sender unit, which sends the fuel level information to the fuel gauge on the dashboard.
