2013 Dodge Ram 1500 owners may notice a sudden decrease in gas mileage and see the "check engine" light turn on. They may also find that the "eco mode" feature fails to work while in this state, along with the remote start functionality being disabled. When brought to a dealership or repair shop, a diagnostic scan using an OBDII scanner will reveal the issue. Customer reports suggest that the problem stems from loose electrical pins or plugs within the vehicle's system. These disconnected components prevent proper communication which triggers an error code, rendering the eco mode and remote start unusable. By replacing the affected module or pins, the error code can be cleared and eco mode should resume functioning.

My dashboard is indicating a 4 on the odometer and the car isn't accelerating. When I switch off the engine, it goes back to normal, but when I reach freeway speeds, it goes back to 4 and the RPMs double. Now, the check engine light has turned on.

In a 2013 Ram 1500, the check engine light serves as a general warning signal for potential vehicle issues. It activates when the vehicle's computer detects a problem and records a specific error code. By using an OBD scanner, you can access this code to identify the underlying issue, such as a loose gas cap, engine misfire, worn spark plugs, vacuum leaks, low oil pressure, or other issues. Additionally, the light may illuminate to remind you to schedule maintenance as you approach a milestone. While the check engine light may not always indicate a serious problem, it should not be disregarded.
