A. If the APU GND SCANNING menu gives the maintenance message:
OIL TEMP SENSOR P11
associated with Fault Code Number (FCN) 54 or 55
- do a check for damage/contamination of electrical connector P11 of the OIL TEMPERATURE SENSOR (P11)
(1) If the electrical connector P11 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin A and pin B of the OIL TEMPERATURE SENSOR (P11).
(a) If the resistance value is not between 60 Ohms to 200 Ohms:
- replace the OIL TEMPERATURE SENSOR (P11) (Ref. AMM TASK 49-94-15-000-001) and (Ref. AMM TASK 49-94-15-400-001).
(b) If the resistance value is between 60 Ohms and 200 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/J5,B8 to the OIL TEMPERATURE SENSOR (P11) P11/A,B (Ref. ASM 49-61/02).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
