Hi, my AudiTT 03 has an engine warning light on, scanner showed Evap Emission Control System Incorrect Airflow, mechanic took it off, two days later its returned, also car has been taking a few more turn...


Warning: I'm not a professional mechanic but I do have some experience working on Evap codes.
As far as I know, this code will have no effect on the starting or performance of the engine, so you may have a separate issue.
Your Evap Emission Control System can have a number of problems.
Incorrect flow could be caused by debris in one of your Evap lines, a faulty Purge Valve Solenoid, or Charcoal Canister, among others.
A qualified mechanic will have the proper diagnostic tools to test this.
Evap codes can be very hard to diagnose for a mechanic not familiar with these systems.
Other codes that come up sometimes with Evap systems are leaks.
This occurs when the gas cap is loose, or there is a hole rusted in the gas tank or filler neck. This does not sound like your problem, because a leak should show up on the code scanner.

Hello I have 1997 toyota Camry with code 450 and pending code 446 I took the gas cap off this morning with the car running and screwed it back on tight and that's where I got the pending code I hear it...


These codes usually trigger the check engine light to ON if the car is fueled or fuel tank cap is removed with the engine in start position.
To delete the codes, remove the key from ignition, remove the battery negative terminal for 5 Seconds or more. Reconnect the battery terminal, start the engine, let it idle for 10 minutes.
Error Code: P 0446
Description:
Evaporative Emission (EVAP) System, Vent Control - Circuit Malfunction
Possible Cause:
Wiring.
Evaporative emission (EVAP) canister purge valve.
Engine control module (ECM).

Error Code: P 0450
Description:
Evaporative Emission (EVAP) Pressure Sensor - Circuit Malfunction
Possible Cause:
Wiring.
Evaporative emission (EVAP) pressure sensor.
Engine control module (ECM).

Hope that will work. If the problem persists contact a service technician.

Any one of the abope causes will set all three codes.

no
it is more likely that the problem is in the EVAP system
code p 0455 refers to evaporative emission(EVAP)system---large leak detected ====causes --hose connections ---intake leak---EVAP cannister---EVAP canister purge valve
I would suggest to you to tell the mechanic to replace the EVAP purge valve as the problem is more likely to be that than the fuel tank
