                                                           (f)    Use a multimeter to measure the resistance         04
                                                                  between the pin 1, 3, 4 of intake mass flow
                                                                  sensor connector E07 and the ground
                                                                  respectively.

                                                               E07(3)- ground                 > 10 MΩ

                                                               E02(4)- ground                 > 10 MΩ




                 Is the inspection result normal?
                 YES>To step 4.
                 No > Maintain or replace the harness.


                 4 .    Replace the intake mass flow sensor
                 (a)    Replace the intake mass flow sensor.
                 (b)    Use a diagnostic apparatus to perform DTC verification procedures.
                 (c)    Implement the steps to read sensor data stream.
                 (d)    Check whether DTC exists.
                 Is the inspection result normal?

                 YES>Replace the intake mass flow sensor.
                 NO >To step 5.

                 5 .    Replace ECM

                 (a)    Replace ECM.
                 (b)    Use a diagnostic apparatus to perform DTC verification procedures.
                 (c)    Implement the steps to read sensor data stream.
                 (d)    Verify that no DTC exists and the data are normal.
