hi people..

I have a nissan sentra 2000 with 60k about miliage...

I purchased this car from an used car dealer and it runs pretty smooth when we tested it, so i bought it.

After several hours of driving the Service engine soon light poped up.. I thought there was a serious problem but everything runs fine...

I went to a car repairing shop and did a test then i have the p0171 error code... I did some research and i found out its mostly costed by a malfunction of the o2 sensor...

So without spending tons of money and time, is there a way that i can fix or clean this sensor? or is the error costed by some other reasons?

do you have a warranty? if so, they should absolutely, positively cover all of your problems.

ok so you are trying to remove it from the bung, go to an autoparts store and buy the tool, and while your there pick up a new one, as theres no real way to clean an o2 sensor
