Ford Escape: Engine System - General Information / General Procedures - Oil Pressure Test - 2.5L Duratec – Hybrid (121kW/164PS) (BG)

1. Disconnect the high voltage connector.
   For additional information, refer to: High Voltage Connector Disconnect and Connect (414-03A High Voltage Battery, Mounting and Cables, General Procedures).

1. 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 Battery, Mounting and Cables, General Procedures).

1. Remove the EOP sensor. Refer to the appropriate 303-14 Electronic Engine Controls section.
   

1. 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.
