Welcome! My name is ***** ***** I will do my best to assist you with this problem.Ask me about added features such as phone contact anytime if you wish !
is it setting any current or history codes at all ?
if its setting the code P0442 it will not run the evap test
the code P0442 needs to be corrected
once there is NO more code then you reset the monitors an drive it for 75 miles or so
does the fuel gauge work ?
has the vehicle been to a shop to smoke test the EVAP system and find the problem to fix the P0442 code yet ?
if it has a P0442 code it will never run the monitors for the EVAP
the EVAP code has to be fixed for it to run and pass i am sorry to say

if it takes 400 miles and the fuel gauge works fine disconnect both battery cables for 5 minutes then touch the 2 battery cables together for 2 minutes then reconnect both to the battery then drive it 75 miles highway and back roads
that should force the monitors to reset
if it triggers that code or the fuel gauge is erratic enough it can cause the monitor to not run
