P2272 - O2 Sensor Signal Biased/Stuck Lean Bank 2 Sensor 2
- Rear Heated Oxygen Sensor Bank 2 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Exhaust gas leaks
- High Fuel Consumption
- Excessive Smoke from Exhaust
The Powertrain Control Module (PCM) supplies a voltage of about 450 mV between the HO2S high and low signal circuits. The oxygen sensor varies the voltage over a range from about 1,000 mV when the exhaust is rich, down through about 10 mV when the exhaust is lean.
The PCM monitors and stores the heated oxygen sensor (HO2S) voltage information. The PCM evaluates the HO2S voltage samples in order to determine the amount of time the HO2S voltage was out of range. The PCM compares the stored HO2S voltage samples taken within each sample period and determines if majority of the samples are out of the operating range.

i have a 2003 ford windstar there are 3 codes i can not find they are ..p0156.p2272.p2273.:)...
What does the OBD 2 code mean for a 2008 GMC 2500?...
i have changed the o2 sensor and the light still is on would a exhaust leaking cause it to stay on...
