next
2
check whether the data of ‘intake air temperature’ equals
to the real intake air temperature.
Yes
Setp 5
No
Next
3
Remove the connector, and use the multimeter to check
whether the resistance between pin B and D is reasonable
according to the temperature.
Yes
Step 5
No
Next
4
Remove the connector and check whether the voltage
between pin B and D is about 5V.
Yes
Next
No
Check harness
