I'm getting two codes which are PO141 and PO715. The first one says its a sensor heater circuit malfunction or something like that and the other says input turbine speed sensor (A) circuit malfunction. Any encountered these codes before any suggestions will be appreciated.

They are probably just O2 sensors that need to be replaced. I've replaced 2 out of 4 already.. Thats what I think, maybe someone else knows more..

i concur ... probably O2 sensors ... i took mine to my tuner shop when my engine light came on and the guys said it was just O2 sensor 1 and 2 and that it was no big deal i could wait on replacing them if i wanted ... so my light is still on :P
and yes im getting it fixed before the end of the month and no im not neglecting my car

Mine CEL came on recently, it was showing a bad 02. Bank2, sensor2. Lexus dealer wanted right at $400 to replace it. I ordered it from ******************.com for $118. Took me all of 45 minutes to change it out. No more CEL and my gas mileage is MUCH better.

agit8or, I did the same thing with sensor 1...however, my check engine light just came back on again? Has your light come back on since you replaced your sensor?

A "Check Engine " condition may be caused by many different sources.

Suggest you have the OBD II checked for additional failure codes.

Agreed... Make sure you scan the code before you go throwing money at it.
