Another fuelling issue

Hi everybody,
I'm experiencing fuelling issues
Car goes limp without throwing anything on the dash
got 2AAF code

so i just changed LPFP, and then FPR, and still no luck

LPFP sensor read very low ( something like 43 PSI)
what's next ? EKPM ?

nope, didn't change it because pressure isn't stuck at the same level.

i would even say it goes down the more i drive.

can be 72 psi in the morning, and 50 a moment later

I would change the sensor. They don't get stuck at 1 pressure when they go bad, they fluctuate and show sporadic pressures.

You should always start with the lowest cost (potential)solution in cases like this, which would be the sensor.

Perfectly fine. If it was low 50s or 40s then that's too low.
