O2 SENSOR

2006 Honda Accord • 130,000 miles

Hi, ive been having problems with my 2006 honda accord ex. My check engine light went on and so I ran a test with an obd2 scanner and codes p1034 and code p2243 pooped up. I went to autozone and bought a bosch upstream bank 1 sensor 1 o2 sensor. I replaced the old sensor with this new sensor and unplugged the battery to reset the car. I ran the test again and only code p2243 popped up and I looked this code up and it said "Reference Voltage Circuit/Open (Bank 1 Sensor 1)" so my question is what is this? And how to I fix this? Please help. And thank you in advance.

You have an open circuit in the wiring somewhere. Check to make sure the wiring is good at the sensor, there is no corrosion.
