Thanks Glenn!

I'm hoping that doesn't mean I need to replace ALL those components on the car! Couldn't one sensor be the cause of all those errors? Any way to diagnose?

Thanks!

Replace the a/f sensor bank 1 sensor 1 and hope it fix it.

First look should be A/F Sensor (Bank 1 Sensor 1)

1130 and 1135 are 100% AF sensor bank one. You could easy check that sensor with ohm meter, and see if all the connections are open. It is usually heater problem on those sensors. I had to replace one of them 5 days ago, same codes as above. 1150 indicates the front AF sensor, you should check that one also with ohm meter.
