I'm puling both of these codes together, along with a check engine light and the VSC light. I am having an issue with my air conditioner/heater vent. The motor hasn't been working to switch the air flow from the bottom vents to the top center vents. I've unplugged the lower motor to keep it from making a loud obnoxious noise that sounds like gears spinning and rubbing and not actually catching to make the movement they're supposed to. Is it possible these codes are now coming up because of this lower motor heater and A/C issue? It was approximately a week or two after unplugging the lower motor that the codes came up.

 

Totally unrelated. Replace Bank 1 Sensor 1 (by the firewall). https://www.clublexus.com/forums/rx-...el-sensor.html
