**ON A/C 051-099,
A. If the operational test gives the maintenance message CHECK OIL PRESS SWITCH 3EN1:
- replace the RELAY-ENG 1 OIL LOW PRESS (3EN1).
(1) If the fault continues:
- replace the DETECTOR UNIT-TPIS (2GV) (Ref. AMM TASK 32-49-34-000-001) and (Ref. AMM TASK 32-49-34-400-001).
(2) If the fault continues:
- do a check of the wiring from the TPIS (2GV) pin AB/11A to the relay (3EN1) pin A/6 (Ref. ASM 32-49/01).
(a) If there is no continuity:
- repair the related wiring.
(b) If there is continuity:
- replace the CTL SW-ENG/MASTER 1 (3KC).
