Ihave dodge caravan sport 2001 and ihave this code in my car-p0442 how i fixed ?


This indicates a fuel vapor leak in the EVAP control system. It means a very small 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.

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

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
Few places to check - rubber hose under air box (requires removing the air box) and hoses connecting to EVAP system under the van on the drivers side.

A Large leak is almost never a gas cap, thats usually the small leak. Dodge uses cheap hoses that crack badly. Check the canister in the Engine compartment, passenger side. Then check passenger side behind the cab by the frame. 2 canisters and hoses leaving that ,often cracked. Last is a piece that connects from the hard steel lines near the oil pan....one of these three usually

Engine coad po442 how do i fix it


PO442 is the data trouble code for (evaporative emission control system leak detected "small leak") it means that the OBD-II system has detected a small vacuum leak in the evaporative control system.

You will need to find the vacuum leak in the evaporative control system, check for cracked or broken vacuum lines and hoses, especially the vacuum hoses and lines around the evaporative (Evap) canister and the (Evap) solenoid. Also check the gas cap seal for damage.

Vacuum hoses and lines should be checked very well for any cracks or breaks, because they usually hide under the vacuum line or hose.

Error codes p0442 & P0455


Those are both Evaporative Emission Control System related.
442 is a small leak has been detected.
455 is a bigger leak has been detected.
Check all your connections, (electrical & vacuum lines) as well as check for any cracked, loose vacuum hoses in the system, as well as clean "O" ring on your gas cap well and threads in filler pipe & make sure gas cap is tight. Do the gas cap first & see if codes dissappear, but it may take a new gas cap. These codes commonly appear shortly after getting gas, due to cap not back on tight.

2001 dodge stratus check engine light with code p0442 what can it be? thanks


P0442 is a medium evaporative system leak detected. Check your gas cap and make sure it is on tight and the rubber seal is in good shape. If it was loose, tighten it and the check engine light will exstinguish after a few days on its own. If not this usually means there is a small hose in the system that has developed a small split. It could be several other things as well, it is "usually" a hose. You need to take it to a shop that can proform diagnostics to locate the leak.

Here is a list of possable causes;
POSSIBLE CAUSES
LEAK AT GAS CAP

EVAP PURGE SOLENOID OPERATION

INTERMITTENT LDP MONITOR FAILURE

EVAPORATIVE EMISSION LEAK DETECTION

GAS CAP

LDP COMPONENT LEAK

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.
