Question about 2005 Toyota Avalon
I (stupidly) went to the toyota dealership because the check engine light was on. They told me the Diagnosis Code was PO174 system too lean found bank 2 air fuel ratio sensor faulty. Recomended replacing bank 2 a/f sensor. They told us if this doesn't get fixed it can cause major problems with the catalayic converter
We didn't have anything done but when we got our car back the light was off and hasn't come back on again. A mechanic we know personally, told me they might be giving us the run around, and a lot of times the sensor just needs to be cleaned.
Is this something complicated to do, does anyone know how to do this?
Thanks A Million!
Before replacing parts i always like to clear the code and see if it comes back .
there could be a fluke that set the code or poor fuel could also cause this code.
i would continue to drive and see if the code comes back and if it does find a independent garage and get a second opinion. and just play dumb and see what they say.
