When it comes to RAM code P1457, it is important to understand the fuel tank pressure sensor circuit high. This code indicates that the Powertrain Control Module (PCM) is receiving information on the vapor pressure inside the fuel tank. The FTP Sensor is a transducer that varies resistance according to changes in force, and the PCM provides a 5-volt supply and sensor ground. To make sure the system functions properly, it is important to understand the various causes of a Fuel Tank Pressure (FTP) code, as well as their respective solutions.

| Fuel Tank Pressure (FTP) Sensor | Test and replace the FTP Sensor if needed |
| Powertrain Control Module (PCM) | Replace the PCM if needed |
When it comes to RAM code P1457, understanding the fuel tank pressure sensor circuit is essential. This code indicates that the Powertrain Control Module (PCM) is receiving information on the vapor pressure inside the fuel tank, which is sent back to the PCM on the signal circuit. If the fuel tank pressure changes, the feedback voltage will also change proportionally. To keep the system running smoothly, it is important to identify the many causes of this code and the solutions available to address them. Common causes of RAM Code P1457 include an FTP Signal Circuit Shorted to Voltage, an FTP Signal Circuit Open/High Resistance, an FTP Signal Circuit Shorted to the 5-volt Supply Circuit, a Sensor Ground Circuit Open/High Resistance, a faulty Fuel Tank Pressure (FTP) Sensor, or a damaged Powertrain Control Module (PCM). Solutions to these issues include checking for shorts to ground and open circuits, inspecting voltage supply and ground circuits, testing and replacing the FTP Sensor, and replacing the PCM if necessary.
