Subtask 49-00-00-810-159-B ** ON A/C NOT FOR ALL

A. Maintenance Action
(1) If the APU Last Leg Report gives the maintenance message:

INLET T-P SNSR (8013KM):
Fault Code Number: 004 or 005 or 006 or 170

replace the INLET T-P SENSOR (8013KM) AMM 49-23-17-000-001 and AMM 49-23-17-400-001.

(a) If the fault continues:

do a check and repair the wiring (Pressure Side of the Sensor) from the ECB (59KD) AB/A1, A4, C8, C9 to the INLET T-P SENSOR P22/1, 2, 3, 4 ASM 496102 ESPM 2052210 ESPM 2053210 ESPM 205321A.

(2) If the APU Last Leg Report gives the maintenance message:

INLET T-P SNSR (8013KM):
Fault Code Number: 008 or 009

replace the INLET T-P SENSOR (8013KM) AMM 49-23-17-000-001 and AMM 49-23-17-400-001.

(a) If the fault continues:

do a check and repair the wiring (Temperature Side of the Sensor) from the ECB (59KD) D3, E6 to the INLET T-P SENSOR P22/ 6, 5 ASM 496102 ESPM 2052210 ESPM 2053210 ESPM 205321A.

Subtask 49-00-00-710-265-A ** ON A/C NOT FOR ALL

B. Do the test given in Para. 3.
