8. Place ignition switch in OFF
position. Disconnect sensor
harness from intake air
temperature
sensor
and
disconnect sensor harness

the
following
resistance
checks:
If engine harness requires
replacement, notify SRA.
a. Measure resistance from

connector to engine block
ground. Resistance should
be greater than 100k ohms.
b. Measure resistance from
pin 38 of sensor harness
connector to engine block
ground. Resistance should
be greater than 100k ohms.
