where is the map sensor on a 03 4l ranger (no EGR)

That vehicle uses Mass Air Flow system.

MAP Sensors were only used with Speed Density System.

Short answer... you don't have one.

thanks for the reply, I ordered an o2 sensor from amazon, they had a map sensor listed, I could not find one so I had to ask,

2.3 duratecs have MAP sensors. top rear of intake.
the 2005 manual has it shown on page 303-14-16
there is no mention of one on a 4L engine, so it's only on the 2.3
