Hi. You need to clean the Mass Air Flow Sensor.
This is an easy job.
Get a can of throttle body or brake cleaner spray at your local auto parts store.
Open the hood, and locate the air filter box. follow the tube from the filter box towards the engine. Look for a small black box with 2 screws holding it to the air tube, Remove the wire connector and observe inside the sensor with a flashlight. You will see 2 small wires, and they will appear fuzzy or dirty. Spray the interior with the cleaner until the wires are nice and clean. Do not use compressed air, you will damage the sensor. Put it all back together and drive it.
This will def fix your issue. This is a vey common problem. If you do it yourself, you will save 70 + bucks.
Thanks for choosing FixYa, and a FIxYa rating for my assistance would be greatly appreciated.

Disconnect your battery for 10 minutes after which you connect it back the lights should go off. Don't report to toyota. Nigerian style!

bank one is the bank closest to the firewall in the manifold but if you replace this one you should do the other or you will get a code for it not long from now because the new sensor will operate much better and faster

If the code has cleared on its own then you need to disconnect the battery and re-connect it. This will clear the codes out of the memory. If you don't want to do this you can go to an auto parts strore and have them hook the little computer up to your car and they can clear out the code as well.

The code P0170 means that the air-fuel mixture coming in to the engine is too lean, or too rich. Usually it's the lean condition that causes this code. The code P0173 means the same, only for the Bank 2. Some car manufacturers list the description for the code P0170 as self adaptation out of limits.
The code P0170 could be caused by a number of reasons, such as vacuum leaks, bad PCV valve, or other parts of crankcase ventilation system, low fuel pressure, bad oxygen sensor, bad MAF sensor or even a bad EGR vlave.
