Did you replace the sensor? Did you check your engine coolant if its brown ?

There is a conflict on the DTC P1273 definition given by auto zone vs. the OBDII definition and the one found on service manual. The OBDII and Manual are in agreement so auto zone is incorrect.

Update
Hey Guys,
Update on my issue.. I had the head gasket replaced..drove the car for a week.. no more radiator fluid top up required as well as the radiator fluid is not turning brown and frothy anymore..but the code is back 1273.. as well as I now have a new code P1612 .. I am guessing that the local garage that worked on the car did not do the proper erase procedure hence the code came back for P1273.. and as for P1612.. once I tried to use my other 06 Altima (I have both 05 and 06 Altima) key bymistake.. the ignition didnot turn but my guess is that cos I did enter a non programmed key in the ignition and thts why it threw the code P1612. Any comments/help.. ? Last edited by Stealthm; 08-08-2012 at 09:09 AM. |

Try using your original key turn the key on for 5 seconds and then off for 10 Do it 3 time DO NOT START THE CAR UNTIL THE THIRD TIME! and it should reset the code.
About 1273 read my post above to clear the data! |

P1610 to P1615 - is your NATS (Nissan Anti-Theft System). When you used the wrong key I'm sure you tried to crank the engine at least 3x, after that ECM put car in lockdown. I hope "ritter" suggestion works, otherwise you need to tow your car to dealer and bring all your keys for that car as they need to be initialized (programmed) again.

3 days.. No code yet.. ..
But I think I would be sure that the problem is solved only if the code doesn't show up for the next 4 days.. Cos in the past I have had the code back in 2-3 days.. |

P1273 Nightmare
I have a P1273 code on my 05 Altima. Changed both O2 sensors, and replaced cat. Still have P1273. Replaced MAF sensor. Still have P1273.
I read through TSB NTB06-039a on this site. Can anyone tell me exactly what is changed with the re-programming that this TSB mentions? Any help would be appreciated. |

since you replaced the O2 sensors, check the link below for other causes of the code and possible fixes. for future reference, at the bottom of each page is the link to obd-engines codes.com. when you have the trouble code just enter and click search to get the definition.

All has been checked and verified good by a local Nissan dealer. They did not have an answer. I've tried re-doing the learning process as stated in another thread. No luck. Nissan said my ECM may have to be re-programmed. I found this in TSB NTB06-039a. Not sure what exactly what the re-programming does. Do you know? Its annoying because Nissan should know there is a problem since there is a TSB on it. I have read MANY threads within Nissanhelp, but I can not find a fix for this other than to re-program. P1273 is such a generic code that it has made it a major ordeal to pinpoint the problem. After $1000 worth of changes, its time to back off and ask for help. HELP?

After reading this thread, I am losing hope that it ended like a murder mystery. In still looking for answers on this one myself.
