Upstream O2 oxygen sensor, 2006 Tundra 4.7L V8

Upstream O2 oxygen sensor, 2006 Tundra 4.7L V8
Hello everyone,
Recently the check engine light turned on in my 2006 Tundra 4.7L V8, and I noticed my fuel economy seemed to be suffering.
I used my ELM327 Bluetooth dongle to read the codes:
Current fault
P0051 - Powertrain - HO2S Heater Control Circuit Low (Bank 2 Sensor 1)
Pending fault
P2197 - Powertrain - O2 Sensor Signal Stuck Lean (Bank 2 Sensor 1)
It seems to be a dead upstream O2 sensor. My mechanic quoted $280 for the sensor, plus labour. This seems like a lot of cash so I started looking into doing it myself.
I located the following parts from Denso:
DENSO 234-9051 Air-Fuel Ratio Sensor (around $110-120 on eBay)
DENSO 234-4260 Oxygen Sensor (around $50-60 on eBay)
Trouble is, I can't get solid info on which is the appropriate one for the upstream sensor.
Could someone guide me toward the correct part, please?
Thanks very much
