Lincoln Nautilus: Engine System - General Information / Oil Pressure Test - Gasoline. General Procedures
Oil Pressure Test 2.7L EcoBoost & 3.3L Duratec & 5.0L Ti-VCT
-
NOTE:
It is necessary to disconnect the battery to avoid
setting any DTCs that could cause the PCM to command the oil pressure to
other than what should be observed from a correctly operating system
during the oil pressure test.
Disconnect the battery ground cable.
For additional information, refer to: Battery Disconnect and Connect (414-01)
.
-
Remove the EOP sensor. Refer to the appropriate 303-14 Electronic Engine Controls section.
-
NOTE:
The VDOP (variable displacement oil pump) solenoid and the EOP sensor
must be connected and functional during the oil pressure test.
Assemble the oil pressure adaptors as needed to the oil
gallery port. Install the commercially available oil pressure gauge.

All vehicles
-
Run the engine until normal operating temperature is reached.
-
Run the engine at the specified rpm and record the gauge reading.
-
The oil pressure should be within specifications. Refer
to the 303-01 specifications procedure for each engine for the
acceptable oil pressure range and specific vehicle requirements.
-
If the pressure is not within specification, check the following possible sources:
