The Dodge Ram P1D73 code is associated with the Active Grill Shutter (AGS) performance. When this code appears on your vehicle, it means the Powertrain Control Module (PCM) has received an indication of a malfunction in the AGS system.
In particular, the P1D73 code signifies that the AGS actuator’s open to close position travel is above 100 degrees, or the mechanical stop was detected before the commanded position was reached. Addressing this issue in a timely manner is crucial to ensure your vehicle operates efficiently and maintains optimal fuel consumption.
Symptoms and Diagnosing the Dodge Ram P1D73 Code
Check Engine Light Indicators
When the P1D73 code is triggered in your Dodge Ram, one of the first signs you might notice is the appearance of the Check Engine Light (CEL) on your dashboard. This light indicates a malfunction in your vehicle’s systems, and utilizing a code reader can help you pinpoint the specific issue. In this case, the code you retrieve will be P1D73, related to the Active Grill Shutter (AGS) system.
Performance and Functionality Issues
Upon diagnosing the P1D73 code, you may notice some performance and functionality issues with your vehicle. Some common symptoms include:
- Decreased fuel efficiency: The AGS system helps improve aerodynamics and fuel economy by controlling the airflow through the engine’s radiator. If it is malfunctioning, you may experience lower gas mileage than usual.
- Difficulty starting or poor engine performance: A faulty AGS can negatively impact the engine’s general efficiency. This may lead to difficulty starting the engine or less-than-optimal performance while driving.
To ensure that your vehicle is working correctly, it’s essential to address any performance and functionality issues related to the P1D73 code promptly. Consult a professional technician or your local dealership to help diagnose and fix the problem, ensuring the best performance and safety for your Dodge Ram.
Potential Causes of Dodge Ram P1D73 Code
Faulty Active Grill Shutter Actuator
One of the possible causes of the P1D73 code is a faulty Active Grill Shutter (AGS) Actuator. The AGS Actuator is responsible for the movement of the active grill shutters. If it is not functioning properly, the shutters may not open or close as needed, leading to this diagnostic trouble code. It’s crucial to inspect and test the actuator to determine if a replacement is needed.
Problematic Wiring
Another common cause of the P1D73 code is problematic wiring. In some cases, the Active Grill Shutter (AGS) Actuator harness might be open or shorted. This can lead to the circuitry not functioning as it should and can cause the code to appear. It’s important to thoroughly examine the wires for any signs of damage, such as fraying, corrosion, or disconnection. If needed, repairs or replacement of the wiring should be carried out to resolve the issue.
Poor Electrical Connection
A poor electrical connection within the Active Grill Shutter (AGS) Actuator circuit can also trigger the P1D73 code. This can occur due to loose connections, corrosion, or wear and tear. It’s essential to inspect all electrical connections associated with the AGS Actuator circuit and rectify any issues you may find. Properly securing connections and addressing any corrosion can help you avoid future problems in this area.
By addressing these potential causes, you have a higher chance of successfully resolving the P1D73 code and maintaining the optimal performance of your Dodge Ram. Remember to always consult a professional mechanic if you are unsure about any repairs or diagnostics to ensure the best possible outcome.
