The code PO442 is a small leak somewhere in the evaporative emissions control system, the best way to find that is to take to a shop that does smoke tests for emissions.
As far as the nozzle, try changing the position of it the next time you get gas.

PO441 code comes on- Evap purge control valve. also, when filling the gas tank, the nozzle on the gas pump keeps shutting off before tank is full.


Try not putting fuel nozzle in so far. Fuel flow cuts off on back pressure of the air being displaced by the fuel when filling. Can be a problem with narrow neck tanks and some fuel fillers are more sensitive than others.

I have a 2011 ram 1500 slt with the 4.7 ltr v8 engine. i have to hold the pump handle barely on to fill up my tank


I do this with my Ford van also. checked the hoses. Found if I barely put the nozzle in the gas fill and pump, it takes it at full pressure. If I shove it all the way in, It keeps cutting off/ spitting out..

When filling up the pump stops as if the tank is full. I know it's not as I can only pump about a quarter of a gallon of gas at a time. I can hold the handle so the flow of gas is so slow it will fill


run the fault codes as the problem is normally about venting and this is a purge valve for the canister problem. having said that there are lot of poorly designed fillers on the market that will not allow quick fills as the pump hose trigger keeps cutting of no no reason. You may have to just take your time when filling like most people do.
In this country lock fillers have been banned and you have to hold the trigger until the tank is full. Stops idiots from putting the nozzle in the tank and then wandering off and allowing the tank to over fill and create a dangerous situation..

Code po442


Code 442 is a small leak in the EVAP system. The computer vents the gas tank to the vapor canister when the engine is running. There is a leak in that venting system.
Sometimes the problem is the gas cap, sometimes it is a hose or valve.
A shop would need to check the gas tank and lines for a leak.

Check engine light code PO442


You likely won't notice any drivability problems. P0442 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.

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.

Good luck and hope this helps

Car will not accept gas


try pulling back a little on the nozzle, the tank has an anti rolloverball in the pipe and this sometimes cause it to shut off when the nozzle is stuck all the way into the filler pipe

Trouble code po442


P0442 onepx.gif EVAP System Small Leak (0.040") Detected


EVAP fuel tank or canister vapor hoses leaking or damaged
EVAP system component leaking, damaged or has failed
Fuel tank cap is loose, or the cap release pressure is incorrect
Leak detection pump damaged or leaking

You can try the gas cap first, if that does not help you will need to take it to a repair shop, Small leaks are very hard to find. If you want to know what turns on the light here it is.

Cold engine startup (ECT sensor from 40-90�F and within 10�F of the BTS input at startup), fuel level more than 1/2 full, engine running, EVAP leak test "on", and the PCM detected a leak greater than 0.040� but less than 0.080" somewhere in the system.
This code sets in 2 Trip(s).
