                 Is the inspection result normal?
                 YES>To step 3.
                 No > Maintain or replace the harness.


                 3 .    Check oil rail pressure sensor harness
                 (a)    Ignition switch: OFF.
                 (b)    Disconnect the battery negative cable.
                 (c)    Disconnect the oil rail pressure sensor connector E04.
                 (d)    Disconnect connector E01 of ECM.

                                                           (e)    Use a multimeter to measure the resistance
