Possible causes
- Faulty Rear Heated Oxygen Sensor Bank 1
- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Exhaust gas leaks
Help with this
When is the code detected?
The Powertrain Control Module (PCM) detected the HO2S12 sensor has reported a lean condition for an extended period during an intrusive test
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
P2270 Description
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
PCMevaluates 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.
