(e) Use a multimeter to measure the resistance
between the pin 3, 4 of inlet manifold 1
temperature connector E08 and the pin 23,
65 of ECM connector respectively.
Standard resistance

E08（3）- E01（23） ＜10 Ω
E08（4）- E01（65） ＜10 Ω
(f) Use a multimeter to measure the resistance
between the pin 3, 4 of intake manifold 1
temperature connector E08 and the ground
respectively.
Standard resistance
Multimeter connection
Standard value
pin
E08（3）- ground ＞ 10 MΩ
E08（4）- ground ＞ 10 MΩ
Is the inspection result normal?
YES>To step 4.
No > Maintain or replace the harness.
