2003 Toyota Tundra Code P0171, I cleaned my aftermarket air filter, now p0171 and p0174 lean codes. Most common cause of this code is vacuum leak in your intake system.sure there are other possible problems too. It’s not the most complicated obdii trouble code to diagnose.

If the p0171 is combined with the p0174 code, it's very likely that the problem is caused by an intake leak. P0031 is most often not accompanied by any noticeable symptoms as long as it is the only code that is currently stored in the ecm’s memory. Most common cause of this code is vacuum leak in your intake system.sure there are other possible problems too.

It is code p0174 not p0172 as i was told. In this article i am going to be discussing the 1.8, 2.4 4 cylinder engines in the toyota corolla, camry, rav4 and matrix along with the v6 3.5 liter engine used in the camry, avalon, solara and sienna van. If the problem persists the front oxygen (o2) sensor may need to be replaced. Of course, this code can also signify a bad o2 sensor in bank 1. So i would think that it is getting correct voltage to it.
