Reset ion computer can i get it inspected now

Tom, Yes, you should check all evap hoses for cracks and leaks.
Common Problems That Trigger the P0442 Code

• Defective or damaged fuel cap
• Distorted or damaged Fuel Tank Filler Neck
• Small tear or puncture in the Evaporative system hose(s) and/or Carbon Canister
• Defective Fuel Tank Sending Unit gasket or seal
• Small split in a seam of the Carbon Canister
• Defective Evaporative Vent Valve and/or Evaporative Purge Valve
• Defective or damaged Fuel Tank
• Defective Fuel Tank Pressure Sensor
• Defective Leak Detection Pump
• Slightly loose and/or worn clamps or hardened O-rings anywhere in the EVAP system Check the attached links,

How Diagnose Check Engine Light Code P0456 Small EVAP Emission Leak

Volvo S70 Evap Small Leak Common Problem P0442 Charcoal Canister Hose Fix

Can't tell you any more than you have on printout

Need a repair shop to diagnose what you were given

Could be the P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty

When is the code detected?
- An excessively high voltage signal is sent to ECM through the valve

Try to remember this code number for additional details. Hope this helps, keep us updated.

PO 441 -is an EVAP System problem

The Check Light tells you that your vehicle
has a system Malfuntion. Have it diagnosed

You can not do EVAP at home too well

Hi, if the code was P0455, there are other possible reasons. The computer fuel tank pressure sensor has detected a leak which could also be in the vapor canister, or the hose from the canister to the purge valve, or the purge valve itself may be leaking. Please inspect the system for these leaks. I may be able to provide some pics of these parts if you tell me your model, year, and engine info.

Evaporative Emission Control System Leak Detected (no purge flow or large leak)
What does that mean? This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms You likely won't notice any drivability problems.
Causes A code p0455 most likely means one or more of the following has happened:

• A loose or improperly affixed gas cap
• A non-conforming gas cap (i.e. not factory/original brand)
• Other leak or damaged piece in EVAP system

Possible Solutions With a p0455, the most common repair is to:

• Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
• Otherwise, replace the gas cap, and/or
• Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

P0446 CHEVROLET - Restricted/Blocked EVAP Vent Path

Possible causes Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition.

computer is seeing a large evap leak. most common cause is gas cap left loose this is why it is throwing up that message. since you have already done that we know there is a leak somewhere else. look underr vehicle and should see a black rectangular box close to gas tank this is the evap canister check the lines hooked to this and just do a visual inspection of hoses see if one has come off. may need to have it checked out we have a machine that hooks into system and pressurizes with "smoke" the smoke leaks out of the problem area and helps diagnose .

Hello Reina.
It isn't going to hurt anything unless your fuel tank is leaking fuel. In which case you should get it fixed.
It could be a fuel cap and if it seems loose or worn you should replace it anyway. It may cure the problem.
It may take a while for the light to turn off though, as it will need to run the test and pass before it goes out.
If you need more help, leave a message and I will return to assist.

KL

yes you have a purge valve it is connected to charcoal canister under car

Change the evap vent solenoid canister located near the master cylinder on the right side of the engine or your hoses may be cracked. Good luck!
