When you have P0440, P0441 and P0446, it is a very good bet that the fuel cap was loose, or the fuel cap rubber seal is compromised. You will get all three of those codes every time that the cap is loose. Always make sure that the fuel cap is as tight as you can get it after you refuel.

Hi kelly4578,
Your Air/Fuel Ratio sensor is failing. It is also called the Bank One sensor. The sensor itself is about $200 from a parts distributor and somewhat more than that at a Lexus parts department. Labor to remove the old sensor and replace it with the new one will also run you several hundred dollars.
If you're mechanically inclined, you can tackle this repair yourself. But you must first determine the exact location of the failed sensor. And be careful not to strip the threads in the manifold when you remove the old sensor.
Let me know if this helps and please rate this solution. lone99star

Hi there;
#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps
Farrout!
