Good thread guys im sure this will be pretty helpful to people!

Got this code for the second time...

P0171: Definition: Primary o2 Sensor Malfunction
Explanation: There is a heater malfunction for the primary heated oxygen sensor located on the exhaust manifold. When code is read it should say if the code was thrown because of rich or lean conditions.
Remedy: Clear codes, drive around for ~40miles. If code re-appears then check codes again. If same code replace.

So I bought a new 02 sensor and some seafoam. Hopefully will be replacing by the weekend. Useful thread!!!!!!

So this is he sensor that is on the catalytic converter?

The one right before it.

Ahhh... Okey dokey damn still gotta get under the car. I can see it sitting right below the header just can't reach it...

[CrackerTeg]

Yeah dude. Gotta pay to play! I just forked out $150 for lifetime alignments at Firestone.

Question... the correct way and only way to clear a code once a problem has been fixed is by that machine they use at say like AutoZone??? Will just disconnecting the battery do it or will the code just come back?

We just replaced the 02 sensors on Jade06's car and the code P0171 came up again saying 1 of 2... and that the car is riding lean like Fabulous010's ride . Im guessing the car has to get used to the new sensors and soon should go away....

I got one of those code  readers that can delete a code if needed my friend who lives in my building had his accord doing the same thing even with the battery disconnected still showed lean but after i rested his code hasn't shown up yet i guess car has to get used to it but i could be wrong.

I replaced My Secondary O2 sensor and disconnected my battery for about 30 minutes and it hasn't come back on since. That was about two weeks ago. My guess would be that there is another problem just judging by the fact that mine turned off instantly and hasn't come on since.

Yea he got the code reader from his friend to. I told him to delete the code and see what happens in a few days.


Thanks guys!

Wait which sensor did you change? cuz if the code came back up after deleting it, then you probably replaced the wrong one.

I changed the one on the header first... then we cleared the code. A day later the code came back saying the same code and saying one of two, so we replaced the sensor on the catalytic converter. Code cleared, now it came back again saying the same code and when Elliot's boy check it out further it was saying the car is running too lean. <-- guessing the car is running lean because of the 2 new sensors. The car is in a state of shock lolzzz. I know he was riding for awhile with the CEL on before we changed the 1st sensor! All should be well now hopefully. I will find out this weekend when I head up there.

that sounds like the code would be caused by a dirty maf sensor or a vacuum leak not the sensors on the exhaust.
