_______________
**ON A/C 001-003, 051-062,
A. If the test gives the maintenance message:
OIL SUMP TEMP SNSR P25
and the previous APU SWHUTDOWNS report gives the maintenance message:
START TIME EXCEEDED - OIL SUMP TEMP SNSR P25
or
NO ACCELERATION - OIL SUMP TEMP SNSR P25
- replace the OIL SUMP TEMPERATURE-SENSOR P25 (Ref. AMM TASK 49-91-51-000-001) and (Ref. AMM TASK 49-91-51-400-001).
(1) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/C2, D2 to the OIL SUMP TEMPERATURE SENSOR P25/1, 2 (Ref. ASM 49-61/02).
(2) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
R **ON A/C 063-099, 401-499,
A. If the test gives the maintenance message:
OIL SUMP TEMP SENSOR (8084KM)
with LRU TROUBLE SHOOTING DATA menu information
OIL SUMP TEMP SENSOR SHOWS OUT OF RANGE HIGH
Fault Code Number: 055
and the previous APU SHUTDOWNS report gives the maintenance message:
NO ACCELERATION - OIL SUMP TEMP SENSOR (8084KM)
- replace the OIL SUMP TEMPERATURE-SENSOR (8084KM) (Ref. AMM TASK 49-91-51-000-001) and (Ref. AMM TASK 49-91-51-400-001).
(1) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/C2, D2 to the OIL SUMP TEMPERATURE SENSOR (8084KM) P25/1, 2 (Ref. ASM 49-61/02).
(2) If the fault continues:
