What causes code P0449?
Code P0449 indicates that the evaporative control (EVAP) system vent valve solenoid is malfunctioning. This can be caused by either too little or too much electrical resistance or a mechanical problem with the vent valve itself.
What is the code P0452?
When the Engine Control Module (ECM) purges the stored fuel vapors the pressure goes down. When code P0452 is triggered the ECM has detected an abnormally low voltage for an extended period of time. This can be caused by a faulty sensor, wiring or an EVAP system leak.

Code P0449 Meaning Hydrocarbons form smog when they react with air and sunlight. When the trouble code P0449 is set, this is an indication of the EVAP system vent valve solenoid malfunctioning which results in more hydrocarbons being expelled into the atmosphere.
How much does it cost to replace the fuel pressure sensor?
The average cost for a Fuel Tank Pressure Sensor Replacement is between $244 and $283 but can vary from car to car.
Can you drive with a bad fuel pressure sensor?
As the problem with your fuel rail pressure sensor gets worse, you’re going to begin to find that it will become more difficult to drive your car around due to the issue. Once you reach this point, you should not continue to drive your car around with a bad fuel rail pressure sensor in it.
Where is the fuel sensor located?
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
