Tank Vent Valve Signal DTC Codes

[Majed]

Hi All,

I'm facing an issue with my 2020 Supra. When I partially press the gas pedal, for example, to pass the car in front of me, I get an error code, and sometimes I get a CEL.

Codes are:

195014 Differential pressure sensor; Tank vent valve; Signal: Laying down
191C02 Tank venting system; 2. signal Leite Office: malfunction

When I clear the code and the car is on idle, there will be no issue; codes only appear when I'm accelerating.

I have replaced the purge value, which is located above the intake manifold, and I have replaced all the plastic hoses connected to the intake manifold, also the charcoal canister, which was bad, and I had to replace it.


Also, I have noticed that when I fill up the gas, the fuel tank is filled up with air, and the fuel nozzle keeps shutting down.

Has anyone faced this issue before? and what are your recommendations to overcome this issue?
Is there a ventilation sensor located underneath the car or near the charcoal canister?

i believe the vent valve is integrated with the fuel tank
