01 Explorer - MAP sensor location

Can anyone tell me where the MAP sensor is located on a 2001 Explorer (6cyl)? Can this be changed easily by a non-mechanic?

Thanks, JC

I dunno cause I don't know what MAP stands for. The MAF (mass airflow sensor) up to 2000 is located next to the air cleaner at the beginning of the duct. It's flat and black and has two wires. The IAC (Idle Air Control) valve (also up to 2000) is located on top of the engine right about in the middle. These two sensors have a reputation of needing cleaning or replacement, at least on previous years.

How do you know for sure that the sensor needs replacing? The MAF and IAC are easily replaced and you can probably find an aftermarket sensor for a lot less $$ than from Ford but I would have doubts about putting a Chinese sensor in my Mexican truck (91 Explorer).

For what it's worth, MAP stands for Manifold Absolute Pressure (sensor) - a part of the older 'speed-density' engine control system. My 23-year old LTD (soon to be donated to a better cause) has one of those. Speed-density systems calculated mass air flow from manifold pressure, temperature and engine RPM, instead of measuring it directly by a manifold air flow sensor (MAF). Perhaps less accurate, but they were never plagued by the caked-on dust that ultimately makes MAFs read wrong and cause pinging.
