Be that as it may, do you have any info on the sensor?

Not without the engine code, then it would only be the pin-out, then from the signal you get would be obvious whether it is analog or digital.

Fair enough, thanks for the interest.

All I've got here to go on is that the two wires into the ECU are pins 25 and 49,though I have no way of knowing which is responsible for which data, and its not certain that it's correct at all.
It identifies the system with MAP, as being 'Phase 3 &4 W/o HVAC'

49 = Signal in from MAP pin 4 MAP
25 = Signal in from IAT pin 2 MAP

This is not 100 % as no engine code.
