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.

Title: FMC IN ACFT GAVE ERRONEOUS POS. FLC MISSED XING FIX.
Narrative: ALBUQUERQUE CTL GAVE US TO CROSS TONTO AT 12000 FT. AT 16000 FT AND 8 NM FMC FROM TONTO, THE CTLR 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 REF THE FMC. SUPPLEMENTAL INFO FROM ACN 190979: AFTER TKOF (100 FT OR LESS) FROM DEN 35L THE TAT/SAT INDICATOR WENT BLANK. AUTO THROTTLES STARTED REDUCING PWR WHICH WAS WRONG. DISCONNECTED AUTO THROTTLE AND SET ESTIMATED TKOF PWR. THIS MALFUNCTION WAS A 'SEAT- OF-THE-PANTS' THING. I DID NOT KNOW WHAT WAS WRONG UNTIL MUCH LATER DURING CLBOUT. DENVER WX, ENRTE WX AND PHX WX WERE ALL SEVERE CLR OR I WOULD HAVE RETURNED TO DEN. I ELECTED TO CONTINUE TO PHX WHICH IS ALSO A MAINT STATION.
