My '07 Lucerne has a digital MAP sensor...I cannot find a replacement anywhere...all I can find are the Analog sensors...any help would be greatly welcome...Best, Glider

What do you mean by "digital MAP sensor"?

It'* a 3800 V-6, nothing enormously special about it.

Can you post some pictures?

This model has a digital Manifold Absolute Pressure Sensor, as opposed to an Analog Sensor

You may have a digital EGR but you do not have a digital MAP.

Where are you getting this bit of information?

Can you post some pictures of the MAP sensor?

what would be digital? The 3800 N/A has a map sensor on top of the PCV valve location , and the fact is HAS the sensor makes it analog pretty sure. digital would be like how some engines use the MAF sensor to infer the MAP or rather BARO readings. The cars do to, but the MAP reading is truly being measured.
