2000 toyota corrolla engine light on.

Depending on what the actual trouble code is, you would start by testing the component and the circuit back to the computer.
And yes you would need to erase the code once the problem is fixed.

Here is the definition of the code.
Possible causes are a defective gas cap or a leak in the vent system.

P0441 DODGE Description The vapor pressure sensor, Voltage Solenoide Valve (VSV) for EVAP, Voltage Solenoide Valve (VSV) for canister closed valve (CCV) and Valve Solenoide Valve (VSV) for pressure switching valve are used to detect abnormalities in the evaporative emission control system. The ECM decides whether there is an abnormality in the evaporative emission control system based on the vapor pressure sensor signal. Diagnostic Trouble Code (DTC) P0441 is recorded by the ECM when there is a malfunction in either the VSV for EVAP, the VSV for pressure switching valve, or in the vapor pressure sensor itself, or when evaporative emissions leak from the components within the dotted line in Fig. 1 below.

The ECM closes the CCV and opens the VSV for pressure switching valve causing vacuum to increase in the entire EVAP system. The ECM continues to operate the VSV for EVAP until the vacuum is increased to a specified point at which time the ECM closes the VSV for EVAP. If the vacuum did not increase, or if the vacuum increased beyond the specified limit, the ECM judges the VSV for EVAP and related components to be faulty.

Engine check light code p0447 on 2001 Hyundai Santa Fe

The code you cite, P0447 - Evap. Emission Ctrl. System - Vent Circuit Open
This vent circuit is call the CCV (Canister Close Valve). This valve normally stays 'OPEN' to allow outside air flow through the charcoal canister, which absorbs fuel vapors when you put gas in the tank, then the engine vacuum pulls air through it to recollect the fuel vapors and burn them in the cylinder combustion process.

There is a two-pin connector connector plugged into/connected to the CCV. Perhaps it somehow disconnected itself or some foreign object damage the wire harness breaking the connection (circuit 'open' condition), which would set this code. Another possibility is the CCV coil (Solenoid) has an open coil/contacts in it. Regardless, before you start throwing money after parts, have it properly diagnosed first. The problem may simply be a loose/oxidized connection/contact between the CCV and the ECU.

Hope this helps.

I have 2006 GMC Sierra SLE 4WD 5.3 liter and my engine light comes on giving me the code PO449 Evaporative Emission Control System Vent Valve/ Solenoid Circuit Malfuction. What could cause this code to...

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.

Check engine light came on my 2002 Rav 4. Auto Zone diagnostic code PO446. How should I fix?

Chances are, it's going to be either 1 of the 3 switches that need replacing, a new gas cap or a new charcoal canister. The 2 switches under the hood are the VSV for CCV and VSV for EVAP. The one at the canister itself is the VSV for VSP. This VSV for VSP typically goes bad before the other 2 switches do. Plus, the switches are much cheaper than a new canister. (BTW, VSV stands for vehicle switching valve.)

PO446 is an evap canister code
