code p2271

[JamesMills]

this code came on my dodge. i took it to the dealer and they said they put a new wiring harness on. it was ok for a few days and then on again! took it back and they said everything is fine. picked it up went for couple days again and same thing. code p2271. the dealer is saying nothing is wrong.

anyone else have this problem

thank you.

Looks like a bad O2 sensor, there's an actual problem causing the sensor to set off the CEL.

What did the dealer say they did to fix it?

Its a sensor, as long as the operation is not being effected I would wait it out, eventually the sensor will fail completely then the tech will be able to locate and replace.
