DIAGNOSTICS - ENGINE CONTROL SYSTEM 04-199

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

Standard resistance

Multimeter connection 04
Standard value
pin
E07（1）- ground ＞ 10 MΩ

E07（3）- ground ＞ 10 MΩ

E07（4）- ground ＞ 10 MΩ

Is the inspection result normal?
YES>To step 5.
No > Maintain or replace the harness.

5 . 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 intake mass flow sensor.
NO >To step 6.

6 . 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.
