P0454
Evaporative Emission Control System Pressure Sensor Intermittent
DTC P0454, sometimes indicated as P045400 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing evaporative emission control system pressure sensor intermittent.
The evaporative emission control system pressure sensor measures the pressure in the evaporative emission control system. The evaporative emission control system is used to prevent the escape of fuel vapors from the fuel system.
Possible causes of this DTC include:
- A faulty evaporative emission control system pressure sensor
- A leak in the evaporative emission control system
- A clogged evaporative emission control system
To fix this DTC, check the evaporative emission control system for leaks, and clean any clogs in the system. If the problem persists, replace the evaporative emission control system pressure sensor.

I have a 06 G6 2.4l 4cyl and lately it has been giving off a strong fuel smell. I smell it when the car is stationary as well as when the car is in motion. I checked for leaks under the hood and car and cannot find any. When i attempt to crank the car it doesn't start until my second attempt. I had a mechanic look at my car and he could not figure out what the issue was. I am becoming more and more worried with this issue. I have a small child and his car seat is located in the passenger rear. I am very concerned for his safety as well as mine. I am afraid that one day my car may burst into flames while we're on the highway, at a red light, at the mall, etc. Putting not only our lives at risk, but also the lives of others nearby. So i took the car to auto zone and they hooked it up to their scanner for free. They gave me this code - P0454 fuel tank pressure (ftp) sensor intermittent.
