## Discrepancy

DURING CLIMB OUT PASSING FL 340,  RECEIVED AN ANTI -ICE SENSOR FAIL ALERT.   WING, TAIL, & ENGINE ANTI-ICE WAS OFF.  TROUBLESHOT IAW FIM 36-11-01 FIGURE 103.  ANTI-ICE SENSOR FAIL ALERT DISAPPEARED WHILE  FOLLOWING FIM PROCEDURE.  ONLY SENSOR SHOWING A  FAULT IS PE2 X'D OUT IN PSC-1.  ALL  OTHER SENSORS APPEAR TO BE WORKING NORMALLY IN  PSC-1 & PSC-2.  TROUBLESHOT   PE2 SENSOR IAW FIM 30-12-03-00 AND WAS HARD FAULTED WITH A HISTORY ALREADY ON MEL.  WHILE TROUBLESHOOTING, HAD PE1 SENSOR WITH  INTERMITTENT FAULTS, WHEN PE1 FAULTED ANTI-ICE SENSOR  FAIL MESSAGE WOULD APPEAR.  REPLACED PE1 SENSOR  REF 36-11-05-4 NO MESSAGES, PE2 STILL ON MEL.  REPLACED PE2 PRIMARY & PE2 BACKUP SENSORS.
