Narrative:
Selected takeoff power engines responded normally approximately 50 KTS received master caution with an engine annunciator. An abort was initiated at approximately 90 KTS. Returned to gate to await maintenance. Subsequent bites on both engines revealed that no engine abnormalities were noted. FMC noted that there was an interruption in power to the aircraft probe heat, could not substantiate this in the cockpit.
Original NASA ASRS Text
Title: A B737-300 REJECTED TKOF AT 90 KTS DUE TO 'ENG' MASTER CAUTION WARNING. SUSPECTED CAUSE INTERRUPTED PWR TO ENG PROBE HEATERS.
Narrative: SELECTED TKOF PWR ENGS RESPONDED NORMALLY APPROX 50 KTS RECEIVED MASTER CAUTION WITH AN ENG ANNUNCIATOR. AN ABORT WAS INITIATED AT APPROX 90 KTS. RETURNED TO GATE TO AWAIT MAINT. SUBSEQUENT BITES ON BOTH ENGS REVEALED THAT NO ENG ABNORMALITIES WERE NOTED. FMC NOTED THAT THERE WAS AN INTERRUPTION IN PWR TO THE ACFT PROBE HEAT, COULD NOT SUBSTANTIATE THIS IN THE COCKPIT.
