## Discrepancy

NEW FAN AIR TEMP SENSOR PLACED IN COCKPIT BEHIND FIRST OFFICER`S SEAT.  REPLACED FAN AIR TEMP SENSOR ON NR 2 ENG.  DURING OPERATIONS CHECK AIR SUPPLY BITE MODULE LIGHT STAYS ON.  THE BOX WILL NOT TEST.  REMOVED CANNON PLUG FROM NEW FAN AIR SUPPLY TEMP SENSOR & BOX TESTED GOOD.  NEED TO REPLACE FAN AIR TEMP SENSOR AGAIN BECAUSE BAD FROM STOCK MR36112-192 ON-OFF-102.
