SOURCE: evaporative emission control system

The evap system allows for gas vapors to be recirculated through the system and burned by the engine,rather than vented into the atmosphere.

It means that the Gas cap is bad,the evap canister is clogged,you have a bad hose,or a sensor is bad.Replace the gas cap first,This is a common problem.

First thing to check is the gas cap, make certain it is tight and the cap seal is not damaged or cut. In many cases this is the root cause for the P0455.
If that checks good, you want to check the vacuum hoses from the EVAP purge solenoid under the hood, all the way back to the EVAP canister. Make certain all are connected and not damaged or cracked.
Let me know.

Check all of your EVAP lines and the charcoal canister. Also check the lines and overflow line from the gas cap to the gas tank.

Evap system code after some time GMC sonoma 2000 2.2


I would start fuel cap. Check the o Ring. If in question replace it and reset your check engine light. Then I would inspect the evap system from the fill, to the tank, and up to the engine. Could be the selenoid or the carbon filters if they are on this vehicle.

P0446 Evaporative Emission System Vent Control Circuit.
The following are descriptions of all Evaporative possible codes:

P0441 Evaporative Emission System Incorrect Purge Flow
P0442 Evaporative Emission System Leak Detected (small leak)
P0443 Evaporative Emission System Purge Control Valve Circuit
P0444 Evaporative Emission System Purge Control Valve Circuit Open
P0445 Evaporative Emission System Purge Control Valve Circuit Shorted
P0446 Evaporative Emission System Vent Control Circuit
P0447 Evaporative Emission System Vent Control Circuit Open
P0448 Evaporative Emission System Vent Control Circuit Shorted
P0449 Evaporative Emission System Vent Valve/Solenoid Circuit
P0450 Evaporative Emission System Pressure Sensor/Switch
P0451 Evaporative Emission System Pressure Sensor/Switch Range/Performance
P0452 Evaporative Emission System Pressure Sensor/Switch Low
P0453 Evaporative Emission System Pressure Sensor/Switch High
P0454 Evaporative Emission System Pressure Sensor/Switch Intermittent
P0455 Evaporative Emission System Leak Detected (large leak)
P0456 Evaporative Emission System Leak Detected (very small leak)
P0457 Evaporative Emission System Leak Detected (fuel cap loose/off)

---
At least the cap isn't loose for the gas tank.

I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
