The instructions for resetting the Oil Life Monitor are in the "Maintenance" section of your owner's manual in the sub-section on "Engine Oil Check". You might try that, then of course you'll have to track to your next change by miles/time and reset it then to get 'back on track'.
Per the workshop manual, Section 413-01, the oil life settings are indeed stored in the PCM's non-volatile RAM so if your PCM was replaced it should not be surprising that the OLM data is off.
As a matter of 'complete disclosure' for those following your saga it would be good if you provided your year, engine, drivetrain and trim level info in this thread (even better in a sig-block that follows all your posts). It would also be of interest to know the months and miles you have on your Escape.

I love my hard-working '05 F-150 XLT 5.4 V8 trailer-towing truck, too !
Help us help you - what is your year, engine, drivetrain, trim and SYNC version?
