Causes and Fixes P2272 Code: Oxygen Sensor Signal Biased/Stuck Lean (Bank 2 Sensor 2)

How to fix P2272 Code: Oxygen Sensor Signal Biased/Stuck Lean (Bank 2 Sensor 2)
A P2272 code is set when the Bank-2 Sensor-2 oxygen sensor reports a lean air-fuel mixture.
A lean condition exists if the engine is getting more air than fuel in the cylinders. (Air/Fuel Ratio is wrong)
P2272 code can be problematic since it can be caused by many things.
Causes of a P2272 code include a vacuum leak, fuel delivery issues, exhaust leaks, intake air leak, a faulty computer, bad oxygen sensor or other sensor.
Possible Causes of a P2272 Code:
Bad Oxygen Sensor
Wiring (Open Short)
Exhaust Leak
Lean Running Condition (Usually Will Have Other Codes)

Just replaced this sensor in July and back having this code again. I did see the wires had been up against the exhaust pipe just before the sensor when I did it in July so I made sure it was zipped clear of the exhaust tube. I'm getting no other codes other than she's gulping fuel...how do you check that the sensor itself isn't faulty outside the system? Do you hear that sensors from some 'zon suppliers are bad?

Thanks for sharing!!!!

But where is it on an 08 escape?

[@stephenbuchholz3079]

I found it by myself... Just realized you hadn't answered this inquiry? Hmmm
