Hi All,
I have a 2005 altima 2.5. Couple of weeks backs, its SES light went on. Checked with local mechanic and code comes P0420. So he advised me to replace O2 sensors. He replaced both the sensors (upper and lower one). After 6-7 miles, SES again pops up. This time the code is different. The code is P1273. I again went to that mechanic and he cleans the MAF with cleaner and cleared the code. After few miles the SES light again come. This time he told me that the upper O2 sensor is not working to he replaced with new one. He also did the self learning as instructed in the below link.
