Just running through this and it appears your engine does not have a MAP sensor. It has a MAF and the PCM uses the MAF and throttle input to determine the manifold pressure.
Is there a reason you are thinking there is a MAP as well? There are engines that have both but your engine appears to only have a MAF. Again the MAP is then a calculated value.
Take a look at the wiring diagram below of the PCM and the pinout charts and you will see that this engine does not have a MAP. The PCM would have a circuit for it and it is not there but the MAF is.
Please let us know if you have other questions. Thanks
