Narrative:

Albuquerque control gave us to cross tonto at 12000 ft. At 16000 ft and 8 NM FMC from tonto, the controller asked us if we would make the restriction. We told him yes, telling him we still had 8 mi to go on the computer (FMC). He told us that we were only 3 mi from tonto instead of 8 mi. We passed tonto at 12000 ft reference the FMC. Supplemental information from acn 190979: after takeoff (100 ft or less) from den 35L the tat/sat indicator went blank. Automatic throttles started reducing power which was wrong. Disconnected automatic throttle and set estimated takeoff power. This malfunction was a 'seat- of-the-pants' thing. I did not know what was wrong until much later during climb out. Denver WX, en route WX and phx WX were all severe clear or I would have returned to den. I elected to continue to phx which is also a maintenance station.
