Answer 1

this car does not use p0001. Check to see if you have an oxygen sensor fuse in the fuse box. I dont see the labels 

I also see a service bulletin the the PCM may need to be updated for a bank 1 sensor 2 oxygen sensors but its for code P0430 

here is the diagnostic procedures for the code
