The gs cap isnt the only reason for this...a cracked hose at the caniste or leak detection pump can cause it....a bad lek detection pump or canister is also a possibility

P0455 and p0442


p0455-- emission control system ( a large leak ) the most common cause is a bad seal on fuel cap, remove and replace cap, if light stats on. replace cap. if not the cap it could be any where in emission system. p0442 is--same as above. Code p0442 indicates a fuel vapor leak in the EVAP control system. To fix this problem, remove and reinstall the gas cap. Clear the codes and drive to see if the codes reappear. If the code appears again replace the gas cap or inspect the system for cuts or holes in the tube or hose. good-day !

Engine code po455


Check this info about P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)

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

Check eng. light is on, scanner sais small emissions leak, replaced rubber connecting lines already. Help


Small emission leak would indicate to me that the exhaust is leaking, maybe, throwing off the O2 sensor.

If it's an evaporative leak, then I would make sure the gas cap is on tight, and that the filler tube is connected with a vapor tight connection to the tank, and that the tank has no leaks in it.

What was the code, exactly, if I might ask?

I got an P0442 emission control system leak (small leak) error code on my 2008 mountaineer. but it come gas capless....what could it be?


Not sure if you mean you do not have a gas cap or not. But if you do not have a gas cap, that is why you have the P0442 code and the check engine light on. The gas cap is part of the emissions system, it has to hold a vacuum. If it does not that is your "small Leak"...

Code, p0442 p0445


P0442 - Evaporative Emission Control System Leak Detected (small leak)

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. 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 P0442 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)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal

Possible Solutions: with a P0442, 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, or
* Inspect the EVAP system for cuts/holes in tubes/hoses



P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted.
Possible Solutions: with a P0445, the most common repair is to:
* Bad or loss contact wires
* Check harnesses, replace it


Hope helps (remember to rate this).

The code is p0442 what dose that mean and what part do i need


this is a small leak in the evaporative emission control system.Most common cause is a loose or faulty gas cap but not always, Sometimes the check valve in the gas cap doesn't seat properly allowing the gas tank pressure to bleed down. The EVAP system needs to see a positive pressure in the tank.

Code pd 455


It means a large evaporative emissions leak. It could be a leaking or broken vacuum leak, or a bad seal on the gas cap even. Clear the code and see if it comes back. If so you can replace the gas cap and inspect vacuum lines for leaks. Replace any that are questionable.

P0455 is a EVAP system leak detected code check to make sure your gas cap is tight or if you put gas in it while it was running and can set it . First tighten the gas cap then clear the code and drive and see if the code comes back.
