- 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 INLET TEMPERATURE SENSOR (P6).
(a) If the resistance is < 72 Ohms:
- replace the INLET TEMPERATURE SENSOR (8010KM) (Ref. AMM TASK 49-23-14-000-001) and (Ref. AMM TASK 49-23-14-400-001).
(b) If the resistance is between 72 Ohms and 200 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/H4,H2 to the INLET TEMPERATURE SENSOR (8010KM) P6/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).

B. If the APU GND SCANNING menu gives the maintenance message:
INLET TEMP SENSOR (8010KM)
associated with Fault Code Number (FCN) 58
- do a check for damage/contamination of electrical connector P6 of the INLET TEMPERATURE SENSOR (8010KM)
(1) If the electrical connector P6 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 INLET TEMPERATURE SENSOR (P6).
(a) If the resistance is > 200 Ohms:
- replace the INLET TEMPERATURE SENSOR (8010KM) (Ref. AMM TASK 49-23-14-000-001) and (Ref. AMM TASK 49-23-14-400-001).
(b) If the resistance is between 72 Ohms and 200 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/H4,H3 to the INLET TEMPERATURE SENSOR (8010KM) P6/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).
