P2277: Your Car’s Oxygen Sensor Needs Attention
The P2277 fault code is related to the downstream heated oxygen sensor (HO2S) in a vehicle’s powertrain. The PCM monitors the HO2S output and expects it to be within a calibrated range.
If the output is biased or stuck rich for too long, the PCM will trigger the P2277 code. This fault code specifically refers to Bank 2 Sensor 3, indicating the location of the faulty sensor. It is important to address this issue promptly, as a malfunctioning HO2S can lead to decreased fuel efficiency and increased emissions.
