I have three codes that come up for my car. P1349, P1155, P1150.

P1155 and 1150 are for you Air/fuel ratio sensor. This sensor is located in the manifold on the radiator side of the engine, I would use the Toyota/lexus sensor it will run around $255 for the sensor and 20 minutes to replace. the P1349 is for oil pressure 99% of the time the engine is lowon oil and a fresh oil change will solve the issue.
