When it comes to RAM vehicles, one of the most common error codes is the P0471 code, which is an indication of an issue with the Exhaust Pressure Sensor 1 Performance. This code is triggered when there is a difference in the readings of the Exhaust Manifold pressure, Intake Manifold pressure, and Ambient Air pressure at key on. It is usually caused by debris plugging the pressure tube, debris plugging the pressure sensor ports on the exhaust manifold, or an issue with the Exhaust Manifold Pressure (EMP) Sensor. If you have this code, it can be a good idea to check out some related service bulletins from the National Highway Traffic Safety Administration. Understanding the causes and solutions of this code can help you identify and repair the problem.
Causes and Solutions for RAM P0471 Code
| Cause | Solution |
|---|---|
| Debris plugging the pressure tube | Check the pressure tube for debris and clean if needed. |
| Debris plugging the pressure sensor ports on the exhaust manifold | Check the pressure sensor ports for debris and clean if needed. |
| Exhaust Manifold Pressure (EMP) Sensor | Test and replace the EMP Sensor if needed. |
| Related Service Bulletins | Check out related service bulletins from the National Highway Traffic Safety Administration. |
Debris Plugging the Pressure Tube
The first possibility when it comes to the RAM P0471 code is that debris may be plugging the pressure tube. This is most likely to be caused by dirt or other debris that has been sucked in while the vehicle is running. To check if this is the cause of the code, you will need to inspect the pressure tube for any blockages and clean them if needed.
Debris Plugging the Pressure Sensor Ports on the Exhaust Manifold
The next possibility is that debris may be plugging the pressure sensor ports on the exhaust manifold. This can be caused by dirt or other debris that has been sucked in while the vehicle is running. To check if this is the cause of the code, you will need to inspect the pressure sensor ports for any blockages and clean them if needed.
Exhaust Manifold Pressure (EMP) Sensor
The third possibility is that the Exhaust Manifold Pressure (EMP) Sensor may be the cause of the RAM P0471 code. This can be caused by a problem with the sensor itself, or by a faulty connection or wiring. To test if this is the cause of the code, you will need to test the sensor and replace it if necessary.
Finally, it can be a good idea to check out any related service bulletins from the National Highway Traffic Safety Administration. These bulletins can provide information on any known issues with the vehicle that could be causing the code, as well as any possible solutions.
Conclusion
In conclusion, the RAM P0471 code can be caused by any number of issues, from debris plugging the pressure tube to a faulty Exhaust Manifold Pressure (EMP) Sensor. To identify and repair the issue, it can be a good idea to check out any related service bulletins from the National Highway Traffic Safety Administration and test the EMP Sensor if needed. By understanding the causes and solutions of the RAM P0471 Code, you can get your RAM vehicle back on the road quickly and safely.
