Hello, my mustang recently started giving me a CEL and these are the codes its been throwing. Here are the descriptions I've found for each:

P0452: Evaporative Emission Control System Pressure Sensor Low Input
P0453: Evaporative Emission Control System Pressure Sensor High Input
P0454: Evaporative Emission Control System Pressure Sensor Intermittent

To me this would indicate that the sensor is bad but I'm not completely sure. Does anyone have any experience with this? If you think it is the sensor is this the correct one to replace or is it a different one? Thanks in advance!

It cud bee as simpel as an lose ore bad filler cap to get thes codes
your link gos to a fuel pressure sensor and thats not the same thing.

the one you want is this

The sensor comes as part of a line which runs between the EVAP canister and the fuel tank, over the rear end assembly. Luckily, you will not need to use a lift and/or drop the tank

You could first try removing the EVAP system from underneath the spare wheel well and blow though it with some compressed air. There could be a partial blockage that's causing the problem.
If that doesn't work, the EVAP solenoid on the driver's side of the said system could be at fault.

Were you drunk when you wrote that? ;) The spelling is atrocious.

ll those codes at the same.time, I would be looking at the sensor wiring first. If checks good, sensor itself.
This is not a.gascap/evap leak issue.

Thank you for the replies! I'll get the car off the ground tonight and check to see if the lines and wiring look good. if so, then ill try to blow out the system and see if that solves the issue.

That's all right. I was just teasing you. ;)
Which part of Sweden are you from? Just follow the advice I gave you earlier. It's easy to do with simple hand tools and you don't even need to jack the car up. Just keep in mind that the part you may need to replace is the EVAP solenoid below the spare wheel well, not the EVAP purge valve that's mounted on the driver's side of the engine bay.
