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


           3 .    Check intake mass flow sensor harness
           (a)    Ignition switch: OFF.
           (b)    Disconnect the battery negative cable.
           (c)    Disconnect intake mass flow sensor connector E07.
           (d)    Disconnect connector E01 of ECM.

                                                      (e)    Use a multimeter to measure the resistance
                                                             between the pin 1, 3, 4 of intake mass flow
                                                             sensor connector E07 and the pin 80, 40, 22
                                                             of ECM connector E01 respectively.
