  • damage/contamination of electrical connector P11
  • OIL TEMPERATURE SENSOR (P11)
  • aircraft wiring
  • ELECTRONIC CONTROL BOX [59KD]
  • Oil Sump Temp Sensor (8084KM)
  • OIL TEMPERATURE SENSOR (8092KM).

3. Fault Confirmation
Subtask 49-00-81-710-088-A ** ON A/C NOT FOR ALL
A. Read-out of ECB Trouble-Shooting Data
   (1) Put the APU MASTER SW to the ON position.
   (2) Get access to the APU LAST LEG/PREVIOUS LEG report.
   (3) Push the '>' adjacent to the related CFDS failure message:
  • the MCDU menu shows:
    OIL TEMP SENSOR SHOWS OUT OF RANGE LOW
    or
    OIL TEMP SENSOR SHOWS OUT OF RANGE HIGH
   (4) Get access to the APU GND SCANNING menu.
4. Fault Isolation
Subtask 49-00-81-810-072-A ** ON A/C NOT FOR ALL
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 - STANDARD 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:
     (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 ASM 496104.
       1 If the fault continues:
Subtask 49-00-81-810-072-B ** ON A/C NOT FOR ALL
A. If the APU GND SCANNING menu gives the maintenance message:

NOTE: With introduction of the ECB Software V2 the wording of the fault message Oil Sump Temp Sensor (8084KM) is not correct. The functional item number of the Oil Temperature Sensor is (8092KM).

OIL SUMP TEMP SENSOR (8084KM)

associated with Fault Code Number (FCN) 54 or 55

  • do a check for damage/contamination of electrical connector P11 of the OIL TEMP SENSOR (8092KM)
   (1) If the electrical connector P11 is damaged/contaminated:
  • do a repair/cleaning.
   (2) If the electrical connector is OK:
  • use a MULTIMETER - STANDARD to do a resistance check across pin A and pin B of the OIL TEMP SENSOR (8092KM).
     (a) If the resistance value is not between 60 Ohms to 200 Ohms:
     (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 TEMP SENSOR (8092KM) P11/A,B ASM 496104.
       1 If the fault continues:
Subtask 49-00-81-810-180-A ** ON A/C NOT FOR ALL
B. If the APU GND SCANNING menu gives the maintenance message:

OIL TEMP SENSOR (8092KM)

associated with Fault Code Number (FCN) 54 or 55

  • do a check for damage/contamination of electrical connector P11 of the OIL TEMPERATURE SENSOR (8092KM)
   (1) If the electrical connector P11 is damaged/contaminated:
  • do a repair/cleaning.
   (2) If the electrical connector is OK:
  • use a MULTIMETER - STANDARD to do a resistance check across pin A and pin B of the OIL TEMPERATURE SENSOR (8092KM).
     (a) If the resistance value is not between 60 Ohms to 200 Ohms:
     (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 ASM 496104.
       1 If the fault continues:
Subtask 49-00-81-710-089-A ** ON A/C NOT FOR ALL
C. Do a check of the APU GND SCANNING menu to verify the fault is not present.
