AboutTed Ritter Expertise I have more than 26 years experience as toyota technician, I will be able to answer most questions related to the toyota product line up to the present year models, I specialize in difficult to diagnose problems but when posting a question please keep in mind that some situations require the used of special test equipment and diagnostic procedures especially as the newer models become more technologically advanced, so without actually having the car on hand I may only be able to try to steer you in the right direction and in some cases may have to refer you to the toyota dealer but at least you will know what you may be dealing with. Please don't hesitate to ask any questions, I will have an answer for you in most cases. When posting a question keep in mind that I reside in the US, although I get questions from all over the world I may not have an answer for models that are not sold in the US, I will do a reasonable search to try to match your model to the US model,please refrain from asking about diesel powered vehicles, I have no information for them. In most cases I will not answer questions about major modifications of OEM components, engine swapping or aftermarket products,please post a question not a statement, please provide enough basic information such as year, model, what engine and if anything has already been done to fix the problem, the more information I get the more I can help without having to ask you more questions.

Question the engine light is on, these are codes that was given to me, when I had a diagnostic engine check on it.I have no ideas what they mean and what to look for. They are PO440, PO441 and PO446. There have been no repairs on this Camry. My wife put a tank of gas in the car on Saturday 10/10/09 and on Sunday morning her engine light came on, she did have a problem putting the gas cap back on, I went out this evening and the cap wasn't on tight.I turn the car on and the engine light was still on. Please Help.
Answer These codes came on because the gas gap didn't seal, if it was only loose, tighten it and then remove the negative side of the battery cable for ten seconds this will clear the trouble codes, if there is diffculty tightening the cap replace it with an OEM cap from the toyota dealer.
