With engine at room temperature (60-90° F),
is resistance between 6816 -3314 ohms?
Using a DVOM, measure the resistance
between IAT sensor connector [89] terminal
1 and ECM Pin 10 on Breakout Box.
Is it less than 1.0 ohm?
NO
Replace IAT sensor. See

Using a DVOM, measure the resistance
between ECM Pins 10 and 7 of connector
[11] on Breakout Box.
Is it greater than 1.0 megaohm?
NO
Examine BK/W wire
in harness for open
circuit and repair.
YES
Using a DVOM, measure the resistance
between ECM Pin 10 of connector [11] on
Breakout Box and ground.
Is it greater than 1.0 megaohm?
NO
Examine Lt. GN/Y wire and
BK/W wire in harness for short
between these two circuits and
repair.
YES
NO
Examine harness
for short to ground
and repair.
To locate sources of intermittents, wiggle
harness while performing steps marked
above by
Bold Asterisk
.
Repair as necessary.
