2004 Sentra
Hi,

A couple of weeks ago I had the SES dash light come on. It showed code P1273 P 01/01..I brought it to my mechanic and he replaced the Oxygen sensor as well as most of the exhaust, including the muffler...The SES came on today with the same error code...Any advice is appreciated..Thanks

RE: 2004 Sentra
That code can also come from a lean mixture. IOW, vac leaks, air leak in the exhaust, bad MAF, or in some cases I have found the Bosch brand O2 sensors to have a high failure rate. You may want to ask your mechanic what he put in there and if that's the case then insist on either a Denso or OEM replacement.

Keep us posted.
