More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.

The error that I'm showing for error code P1133 is
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank). I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done. Hope this helps. Thanks for an honest rating and for using FixYa.
