R 1_ If nothing is found:
R - replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040)
R and (Ref. AMM TASK 73-25-34-400-040).
R (3) If the fault continues:
R - replace the SENSOR-OIL TEMP (4004EN) (Ref. AMM TASK 79-32-15-000-R 041) and (Ref. AMM TASK 79-32-15-400-041).
R (4) If the fault continues:
R - Check carrefully electrical connector at the oil temperature sensor
R (4004EN) for looseness, damaged pins or contamination.
R (a) If damage is found:
R - repair or replace as necessary.
R (b) If nothing is found:
R - do a check of the aircraft wiring between the oil temperature
R sensor (4004EN) and the EIU (1KS1) for open or short to ground
R (Ref. ASM 79-36/01) pin AA/1 to pin AA/10F. Pay particular
R attention to engine to pylon connectors 4005VC-A, 405VC-A,
R 4006VC-A and 406VC-A and to ground wire connections (9951DC,
R 9956DC and 9957DC) on Engine Fan Case (check for looseness or
R contamination).

4. Fault Isolation
_______________
A. Do a visual inspection of the engine to make sure that there are no leaks (Ref. AMM TASK 79-00-00-210-002) .
(1) Do a check of the electric master magnetic chip detector visual indicator (Ref. AMM TASK 79-35-00-040-042) and the magnetic chip detector (Ref. AMM TASK 79-00-00-281-002) and the scavenge screen plugs (Ref. AMM TASK 79-00-00-281-003).
(a) If you find magnetic particles:
- follow the related instructions per (Ref. AMM TASK 79-00-00-281-002) and NDT Manual (section CHIP ANALYSIS).
(2) If nothing is found:
- do a check for cracks/leaks at oil tank, lubrication, external oil supply and scavenge lines.
(a) If there is sign of heavy oil discharge in the center vent tube:
- replace the engine (Ref. AMM TASK 71-00-00-000-042) and (Ref. AMM TASK 71-00-00-400-042). 中國航空網(wǎng) m.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 OIL 滑油(5)
