DTC PO171 indicates a lean condition, this is caused by the air flow meter located just behind the air filter on the intake tube, here is how to fix this trouble code: Remove the air flow meter and clean the very small platinum wires inside the housing of the af meter with an electronic circuit cleaner, it is important not to use anything else, you can get it any radio shack or electronics store, just spray it into the opening to clean the accumulated gunk off the wires, clear the DTC and you will be good to go, install a new air filter.

If the VSC flashing light comes on at the same time on your Toyota Corolla, then there might be a sensor issue, and if you have a warranty, have it back to the manufacturer.

No, but check with a Toyota dealer to make sure.
To reset the check engine light in your 2006 Toyota Corolla, you will need to attach the car to a diagnostic computer. This allows you to pinpoint the reason for the light coming on, select the correct sensor, and reset the light.
Clean the MAF. Then clear the code.
The Corolla could be shaking for many reasons. Start by checking the wheel bearings and brakes for wear. Then check the engine to see if it running rough, causing the shake.
Could be one of a thousand things. Go to a shop and have them read the error code.
Check under the spare tire
Go to Autozone or Advance Auto and borrow their OBD2 scanner and reset it. Easy and free to use

Fuel injection system, fuel trim to lean (bank 1)
You reset the check engine light with an OBD2 scan tool. But first you must repair the problem that caused it to come on. If not it will just come back on again. There is a problem that is effecting emissions.
Usually a problem in the emission control system or fuel cap not installed properly. Have vehicle scanned to determine the problem
Trouble code P0446 means:Evaporative emission control system vent control circuit malfunction
If you are in the market for a used Toyota Corolla you would first want to check out ebay motors and see what they have available. You might also call around to your local car dealerships to see if they can help locate a used Toyota Corolla.
