The P0442 code indicates that there is a small leak in the EVAP system, but this is somewhat misleading. What the code really indicates is that the EVAP system ...

code p 0442 refers to evaporative emission(EVAP) system---small leak detected====causes--hose connections--intake leak--EVAP canister--EVAP canister purge valve
it also refers to --large leak detected====causes fuel cap loose, off---mechanical fault--hose connections---EVAP pressure sensor
code p 0441 refers to EVAP system--incorrect flow detected====causes hoses, intake leak-- EVAP canister purge valve
code p 0446 refers to EVAP system, vent control---circuit malfunction===causes--wiring---EVAP canister purge valve----ECM
if you can remember when the problem started ( after refueling) it may be that the cap is not fitted correctly
it could that in the fixing process , the wiring has not been correctly installed or the problem is the canister purge valve needs attention

Possible causes
- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
What does this mean? Tech notes
The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.
What does this mean? When is the code detected?
Evaporative Emission System (EVAP) control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors
P0455 Mitsubishi Description
This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition.
The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

Trouble Code: P2404 (2.0L L4 VIN 5 Automatic CVT)
Evaporative Emission System Leak Detection Pump Sense Circuit Range / Performance
Number of Trips to Set Code: 1
Trouble Code Conditions:
EVAP vent valve stuck open: EVAP leak check pressure is lower than -0.14 kPa even if EVAP vent valve is operated from OFF (OPEN) to ON (CLOSE) with EVAP leak detection pump ON. EVAP vent valve stuck closed: EVAP leak check pressure is unstable (difference between maximum and minimum is 0.36 kPa or more) when EVAP vent valve is OFF (OPEN) with EVAP leak detection pump ON. EVAP leak detection pump stuck OFF: EVAP leak check pressure is higher than -0.14 kPa even if EVAP leak detection pump is ON. EVAP leak detection pump flow high: Reference pressure of EVAP leak check pressure is lower than specified value (depending on BARO) EVAP leak detection pump flow Low: Reference pressure of EVAP leak check pressure is higher than specified value (depending on BARO).
Possible Causes:

• EVAP leak detection pump (in EVAP leak check module) and/or its circuit
• EVAP vent valve (in EVAP leak check module) and/or its circuit
• EVAP leak check module and/or its circuit
• ECM

which engine?,. we can not guess that. ever
ill answer for 3.6L engine.
Trouble Code: p0498
Evaporative Emission System Vent Valve Control Circuit Low
Number of Trips to Set Code: 2
Trouble Code Conditions:
EVAP canister vent solenoid valve control circuit is shorted to ground circuit.
Possible Causes:

• EVAP canister vent solenoid valve and/or its circuit
• ECM

that is what the FSM page shows. for DTCs
then shows what tests to do.
all that is in the FSM.
read it , do it or get it fixed by those that can.
here is a $4 day pass.

first check the fuses.
then do the tests.

codes po441 po442 po455 po456. code po441 - EVAP system no flow during purge conditions.code po442 -EVAP system small leak detected conditions. code po455 - EVAP system large leak detected conditions.code po456 - EVAP system very small leak detected. possible causes loose damaged missing fuel cap.fuel tank sensor disconnected or failed.

code p 0442 refers to evaporative emission(EVAP) system---small leak detected ===causes --hose connections--intake leak---EVAP canister---EVAP canister purge valve
There is another section --large leak detected in the EVAP system===causes --mechanical fault---fuel cap loose / off--hose connections ---EVAP pressure sensor

getting code p441 could be caused by evap purge solenoid vacuum line loose leaking or restricted, evap purge solenoid faulty, evap purge vacuum line to canister leaking or disconnected,evap canister failed.

CODE PO496 IS EVAPORATIVE EMISSION EVAP SYSTEM FLOW DURING NON PURGE.POSSIBLE CAUSES - BACKED OUT OF TERMINALS, IMPROPER MATING, BROKEN LOCKS, IMPROPERLY FORM, DAMAGED TERMINALS, POOR TERMINAL TO WIRE CONNECTION.
