***Skip to 3:55 to start the gas tank removal.
At the beginning of this video I made an attachment to my hydraulic jack so I can drop down the gas tank. A gas tank jack. The gas tank was 1/8 full.
***NOTE*** Always replace gas cap with genuine Toyota gas cap. Replace cap before replacing vent control valve. If same codes again, replace the valve.
Check engine light on:
P0440 Leak detected in Evaporative Emission System
P0446 Improper voltage at Canister Vent Control Valve .
Friend also noticed gas smell when car has been sitting in his garage.
The gas cap was replaced a couple of months ago.
NOTE:
Gas cap was replaced a couple months ago before this repair.
So when codes pop up again, check engine light on. Chances are 9 out 10 times the fuel check valve is the problem because it has a crack. Replace it with a OEM Toyota fuel check valve. Also it is recommended to replace the hoses.
