P1155 P1150 Toyota - Camry 1998 v6 what could be wrong??

Question

the car smells like gas inside the car while driving

Answer 1

both codes are for Bank 2 sensor 1 oxygen sensor. But see  possible causes below

You might have a fuel injector leak or something. I would have the car check out. 

possible causes:

- Faulty Air fuel Ratio (A/F) Bank 2 Sensor 1
- Air fuel Ratio (A/F) Bank 2 Sensor 1 harness is open or shorted
- Air fuel Ratio (A/F) Bank 2 Sensor 1 circuit poor electrical connection
- Fuel pressure
- Fuel injector
- Intake air leaks
