2011 Toyota Avalon ProblemsCheck Engine Light on Due to EVAP Vapor Canister Fault
The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.
The motor for the rear window sunshade in the Toyota Avalon is known to fail. When this occurs, the sunshade will not extend down the window, and a grinding noise is heard until the motor fails as well.
Replacement of the sunshade assembly is necessary to correct this failure, however, removing the fuse for the sunshade will stop the motor from making the irritating grinding noise.
The VVT-i oil line is known to burst. This is a very large leak which covers the ground, engine, and undercarriage.
If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate. Continued use after these warnings will result in complete engine failure due to oil starvation.
The line is known to be defective, and a revised part has been issued by Toyota, however, this revised part is known for the same issue.
To repair the issue, the line must be replaced, and the engine bay and undercarriage must be cleaned thoroughly.
