Engine Non motoring)
3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the FADEC 1B on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
4. Fault Isolation
_______________
A. The P25 signal is part of the PMUX option only used for Engine Condition Monitoring.
NOTE : If the engine is not equipped in a PMUX configuration, you have
____
two options:
- replace the engine Identification Connector by a connector configured as Non PMUX to definitively avoid further generation of this fault message,
- ignore this fault message.
NOTE : The fault message is generated if the P25 sensor signal is invalid
____
or out of range.
(1) If the maintenance message P25 SNSR LINE, ECU or P25 SNSR LINE, ECU* is not confirmed:
(a) No maintenance is required.

(2) If the maintenance message P25 SNSR LINE, ECU or P25 SNSR LINE, ECU* is not confirmed but is repetitive:
- do a check for leak or blocked P25 sensor and sense line or loose fittings in the fan cowl area.
(a) If nothing is found or if the fault continues:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
(b) If the fault continues:
- do a visual inspection of the P25 probe (Ref. AMM TASK 73-21-80-210-002).
B. Do the test given in Para. 3.A.
(1) No additional maintenance action is required if the fault is not confirmed.
(2) Repeat the fault isolation procedure if the fault continues.
