Toyota Repair - DTC P0171
Expert: Ted Ritter - 10/17/2008

Question
I have a 2000 corola with 85000 miles on it. I got the DTC of P0171. I cleaned the MAF sensor and the light went off for a week and came back on. The code is still the same the scanner says there is a fault with O2 sensor #2. Since the light went off after cleaning the MAF sensor is should replacing the sensor fix the problem or should i replace the O2 sensor???

Fault Code P0171 Nissan Maxima 2001?
When I got the reason for the Service Engine Soon light diagnosed the mechanic diagnosed oxygen sensors need to be replaced and gave me an estimate of $1,000 so I didn't do it because I didn't have the money.

The light went on and off for the next 2 month but is now on all the time. The smog test 2 month later said "oxygen sensor passed"- actually everything passed according to the smog test but the Service engine soon light=on board diagnostic was listed with Fault Code P0171. I read through the answers on Yahoo but I assume there is no leak anywhere because everything else passed - what do you think?

I have filled the tank with Chevron (claiming Techron cleans the engine) but I am on my second filling and the light is still on - what else can it be?

エクストレイルは燃費が悪く、A/Tが4速にシフトアップしないのです。冬季は特に、それでメーカーに言いましたらそういう機構と返事がきました。時速70kmでもA/Tが温まらないと3速のままです。それで燃費は7-9km
カタログは12km.信号器のない田舎でです。
わたしはA/Tが機構的不良と考えています。
ですが日産はA/T不良を改善してくれない。正常と言われますが、カタログの12kmなんてウソです。
わたしの車3A/Tのロックアップ機構無しです。
どんなことでも結構です。ぜひアドバイスを!
