Engine lights/ traction light on

Hey,

New owner of a 2007 Lexus es350. I've done a little reading and I came to the conclusion that it might be the gas cap. I just want too see if anyone here has any input.

Codes I've read... just been resetting them.

P043E- Emmision system leak
P043F- Emmision system leak
P0098- Intake air temp sensor circuit high
P06410 Sensor reference Volatage A circuit open

I believe the dealer cleared them before selling me the car... The light will only appear once every tank after being reset.

New gasket.... No luck. Had the light come back on today. Any other ideas ?

Edit:

Going to try to take the MAF sensor out and clean it this weekend. Will keep this thread updated

I would take it back to the dealer before doing anything . Tell them you sold me the car after you deleted the codes and they are still coming back. I also believe with the right diagnostic machine you should be able to read code history.
