Map sensor,

You do not have a MAP(manifold pressure) sensor, they were used on older Speed-Density fuel injection systems.
You have a MAF(mass air flow) sensor.
I believe there was a MAP sensor referenced on the EGR sensor(DPFE) on some later models, it was built into that unit, it was to read manifold pressure to adjust the vacuum going to the EGR valve.
DPFE sensor failure is not unusual, but a cracked or leaking vacuum line should be check for first.
Popular reference code is P0108
And as always trouble codes don't mean a sensor is bad, the code comes up because computer is reading that a sensor is "out of range", which in most cases means the sensor is working as it should, it is detecting an abnormal condition, and telling the computer.
So could be a loose electrical connector, cracked hose, or bad gas for that matter, lol.
Never replace a sensor, test it
But hey, it's your money

Well, "customer is always right", I bet it took awhile to look up that part number, lol.
