Typical Customer!! Had the map sensor replaced, don't explain why it was
replaced, when it was replaced or any other info about his problem but
blames the person that last worked on it.
I will give you alittle insight on what the P0440 fault is if you promise
not to blame me  if your taillight bulb burns out!!

A P0440 fault is general Evap system fault and could be as much as leaving
your gas cap loose. ( but you probably wouldn't admit to it anyhow.)
Assuming that the gas cap is tight and not hanging off there are a couple
of
hoses that dry rot and could cause this fault to set, One is under the
vehicle at the Canister and the other under the air cleaner. There is also
a
switch called the NVLD  (Natural Va**** Leak Detection) that is supposed to
see a closed (sealed) input when the eva****ative system is sealed and no
leaks are present. If this switch goes bad it will also set this fault
code.
A scan tool would be needed to see this input. With mileage this vehicle
has
I would lean towards the hoses being cracked causing your problem. If you
cant visual see any cracks in any hoses you may have to have a smoke test
performed along with a scan tool connected to verify the fault and
diagnose
the problem.
