If you have encountered the Dodge P1297 code, you may wonder what could be causing the problem. When this code appears, it is important to understand the underlying causes of the issue and to have the right solutions in place to help fix it. In this article, we will explore the grounds of the Dodge P1297 code and provide solutions to help resolve the issue. From a clogged engine vacuum port to a faulty MAP Sensor, there are a range of causes that can lead to the Dodge P1297 code appearing. To help diagnose the issue, it is important to understand the underlying causes and to have the right solutions in place to help resolve the problem. Knowing the cause of the Dodge P1297 code can help to identify the best possible solution that will get the vehicle back on the road quickly and efficiently.
Engine Vacuum Port to MAP Sensor
One of the most common causes of the Dodge P1297 code is a clogged, dirty, or restricted engine vacuum port to the MAP Sensor. The MAP Sensor, or Manifold Absolute Pressure Sensor, measures the pressure in the intake manifold. If the engine vacuum port to the MAP Sensor is clogged, dirty, or restricted, it can lead to the Dodge P1297 code appearing. The best solution to resolve the issue is to clean or replace the MAP Sensor.
MAP Sensor Signal
Another potential cause of the Dodge P1297 code is a MAP Sensor signal that is skewed, or the Sensor is out-of-calibration. If the MAP Sensor signal is not functioning correctly or the Sensor is out-of-calibration, it can lead to the Dodge P1297 code being triggered. The best solution in this case is to replace the MAP Sensor.

MAP Sensor VREF Circuit
A MAP Sensor VREF circuit that is open or grounded can also be a potential cause of the Dodge P1297 code. If the MAP Sensor VREF circuit is open or dropped, it can lead to the Dodge P1297 code appearing. It is important to check the MAP Sensor wiring and replace it if necessary.
PCM Has Failed
The final potential cause of the Dodge P1297 code is a failed PCM or Powertrain Control Module. The PCM is the main computer that controls the engine and transmission. If the PCM has failed, it can cause the Dodge P1297 code to appear. The best solution in this case is to replace the PCM.
