Error Codes After I Ran Out Of Gas ! Help

[Ono]

Bought my 2001 LS 430 with 82000 miles on the clock. Thought I had enough gas when it read that I had 30 miles left in the tanks, when after 2 miles it was empty :(. Walked to the gas station and filled it with 2 gallons. Engine started up fine, but engine light shows up.

Error code P0430 and P0715. Anyone have any idea on how to fix this?

Thanks

Firstly, you need to talk to Mike (Bluesman) I think he's the expert on LPG.

Secondly, how did you transport gas, under pressure, from the petrol station to your car?

Third, look up the OBD code on YouTube, a feast of knowledge is to be had.

Good luck.

I think clarification is required here, when you say "gas" are you refering to LPG/Propane or using the american terminology for petrol?

Thank you Steve. Yes I should clarify. I mean petrol. 91 or 94. I looked up the codes before I posted. What I fail to understand is that I had NO engine light on to indicate any issue before I ran out of petrol, then it came on and after plugging in the OBD2 these codes showed up.

Surely a Lexus is not that temperamental or lacking solidity?

Thanks

Sounds to me like it's something to do with the catalytic converter or you have and exhaust leak somewhere.

Yes that is what the codes indicate, but what I do not understand is that they would not show at all. But then when I run out of gas, suddenly have these two showing? IF it is a fluke, I would prefer no to have a whole bunch of expensive stuff done (anyone know if it would be) :)
