Also cleaned throttle body after installation of sensors. Cleaned MAF before install.

Thanks for postingIt sounds like there may be an intake leak causing the lean condition which in turn causes the Air/fuel and O2 sensor codes, the sensors are reacting to the lean air/fuel mixture so the P0171 should be addressed first. Is there an exhaust leak? Have you checked for a possible intake leak that may let unmeasured air into the intake system?Does the engine idle smooth without misfires?Do you have a way to get fuel trim readings for both banks?
Customer: replied 2 years ago.
No misfires. Cannot get fuel trim readings either. There is an after market ingenuity cold air intake. Pulled off and reattached to make sure it was secure. What is your suggestion on how to locate an exhaust leak. The car has a 2nd generation TRD supercharger installed as well which makes it a little hard to hear any possible exhast leaks.

I think I'm going to have to opt out on this one, sorry.

Hopefully someone else can come up with a solution.

Decided to reclean the MAF sensor cleared codes. Drove about 30 miles. CEL back on with 3 different codes. P0125 P1135 P1155- all seem to point to AF sensor. Could it be I have a faulty AF sensor (just installed), or MAF sensor or could it possibly be an exhaust leak that is undetected.
Expert:  Ted Ritter replied 2 years ago.
Ok, thanks for the reply, those codes are for the a/f sensor bank one sensor one which is located in the exhaust near the firewall, this the #1 sensor that should be replaced. If you already replaced it try another one and use the Denso brand which is the same Toyota uses
Customer: replied 2 years ago.
Already replaced it again as well as front bank 2 sensor. Both Densos. This was done when we recleaned MAF in previous response
