16 Ford Fusion 1.5L. Car is over 60K miles so it's out of warranty.
Check engine light is on, code is P2243: Bank1 Sensor1 02 Sensor Reference Voltage Circuit/Open.
The car drives fine, though fuel economy is below what I would expect it to be.
Seems all I have to do is check fuses and wiring and if everything is OK, change the sensor.
I looked on Rockauto and I'm confused about this. Which one is the correct one? Both have the little "popular" heart icon on Rockauto.
