(f) Use a multimeter to measure the resistance
between the pin 2 of intake mass flow sensor
connector E07 and the ground.
Standard resistance

Is the inspection result normal?
YES>To step 6.
No > Maintain or replace the harness.
6 . 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.
