Hi,
The oil pressure sensor is located under the intake manifold. They have a history of failing. Can you tell me what code was retrieved? Also, if you look at pic 1, it shows location. Note that the pic doesn't show the intake manifold.
________________________________
Here are the directions for removal and replacement. The attached pics correlate with the directions.

Pic 4
Disconnect the electrical connectors from the Manifold Absolute Pressure (MAP) sensor (1) and the Electronic Throttle Control (ETC) (7).
Disengage the ETC harness from the clip (8) on the throttle body. Disengage the wire harness retainers (4 and 5) from the upper intake manifold near the MAP sensor and reposition the wire harness.
Disconnect the following hoses from the upper intake manifold:
Positive Crankcase Ventilation (PCV) (3)
vapor purge (6)
brake booster (2)
pic 5
Disengage the wire harness retainer (4) from the upper intake manifold support bracket (5).
Disengage the wire harness retainer (3) from the studbolt (2).
Remove two nuts (1), loosen the studbolt (2) and reposition the upper intake manifold support bracket (5).
Pic 6
Remove the nut (2) from the support bracket of the heater core return tube (1).
Pic 7
Remove two nuts (1), loosen two studbolts (3) and reposition the two upper intake manifold support brackets (2).
Pic 8
NOTE:
The upper intake manifold attaching bolts are captured in the upper intake manifold. Once loosened, the bolts will have to be lifted out of the lower intake manifold and held while removing the upper intake manifold.
NOTE:
Exercise care not to inadvertently loosen the two fuel rail attachment bolts that are in close proximity of the upper intake manifold attaching bolts.
Remove seven manifold attaching bolts (1) and remove the upper intake manifold (2).
Pic 9
Remove and discard the six upper to lower intake manifold seals (1).
Cover the open intake ports to prevent debris from entering the engine.
If required, remove the insulator (2) from the LH cylinder head cover.

NOTE:
Prior to installing the upper intake manifold, verify that the four fuel rail bolts were not inadvertently loosened. The bolts must tightened in the sequence shown to 7 NÂ m (62 in. Lbs.) (Refer to 14 - Fuel System/Fuel Delivery/RAIL, Fuel - Installation).
Pic 11
Clean and inspect the sealing surfaces. Install new upper to lower intake manifold seals (1).
NOTE:
Make sure the fuel injectors and wiring harnesses are in the correct position so that they don't interfere with the upper intake manifold installation.
If removed, install the insulator (2) to the two alignment posts (3) on top of the LH cylinder head cover.
Pic 12
Lift and hold the seven upper intake attaching bolts (1) clear of the mating surface. Back the bolts out slightly or if required, use an elastic band to hold the bolts clear of the mating surface.
Position the upper intake manifold (1) onto the lower intake manifold so that the two locating posts (2) on the upper intake manifold align with corresponding holes (3) in the lower intake manifold.
