R 1_ If the resistance values are out of the specified limits:
R - replace the harness HJ13 (Ref. AMM TASK 73-21-50-000-046)
R and (Ref. AMM TASK 73-21-50-400-046).
R 2_ If the resistance values are in the specified limits:
R - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001)
R and (Ref. AMM TASK 73-21-60-400-001).
R (2) If the test does not give the maintenance message EOT SENS, J13, ECU:
R - do a check of the connectors on the harness HJ13 between the ECU
R and the oil temperature sensor for absence of loosening,
R contamination, corrosion or damaged pins or sockets,
R - clean, retighten or replace the harness HJ13 as required (Ref. AMM
TASK 73-21-50-210-001).
R (a) If nothing is found:
R - replace the oil temperature sensor (Ref. AMM TASK 79-31-40-000-R 001) and (Ref. AMM TASK 79-31-40-400-001).
R 1_ If the fault continues:
R - replace the harness HJ13 (Ref. AMM TASK 73-21-50-000-046)
R and (Ref. AMM TASK 73-21-50-400-046).
R a_ If the fault continues:
R - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001)
R and (Ref. AMM TASK 73-21-60-400-001).

4. Fault Isolation
_______________
R A. Procedure.
R NOTE : The fault is triggered if the oil temperature sensor (4004EN)
____ R indicates a temperature greater than 140 deg. C while the ECU R temperature sensor indicates a temperature in between - 55 deg. C R and 135 deg. C. This is indicative of a faulty output of oil R temperature sensor (4004EN).
R (1) 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: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 OIL 滑油(26)
