## Discrepancy

WHILE PERFORMING T/C 78273000 FOUND MGS NR: 75-20832. THE T3 SIGNAL IS OUT OF RANGE ON #2 ENGINE. LONG TERM FAULT. GROUNDED - YES. INTERROGATED CDU. FAULT CODE STILL ACTIVE. REMOVED AND REPLACED THE #2 ENGINE T3 PROBE IAW AMM 73-21-07/401. GROUND VERIFICATION TEST IS GOOD. NO LEAKS NOTED. THIS CLEARS PLT.
