Continued from
Test 5.20 (Part 1 of 2).
Disconnect IAT sensor connector [89B] and
examine for damage. Connector OK
YES
NO

Using a DVOM, measure the resistance
between IAT sensor connector [89B]
Terminal A and ECM terminal 7 on Breakout
Box. Resistance less than 1.0 ohm
Repair
connector.
YES
NO
2
Using a DVOM, measure the resistance
between IAT sensor connector [89B]
Terminal B and ECM terminal 26 on Breakout
Box. Resistance less than 1.0 ohm
Examine Lt GN/Y wire in
harness for open circuit
and repair.
YES
NO
Using a DVOM, measure the resistance
between ECM terminal 7 and terminal 26 on
Breakout Box. Resistance greater
than 1.0 megohm
Examine BK/W wire in
harness for open circuit
and repair.
YES
NO
Using a DVOM, measure the resistance
between ECM terminal 7 on Breakout Box
and ground. Resistance greater
than 1.0 megohm
Examine Lt GN/Y and
BK/W wires in harness
for short between these
two circuits and repair.
YES
NO
3
Remove IAT sensor and measure resistance
across the terminals of the IAT sensor
directly. Again, with sensor at room temperature
60-90° F or 16-32° C), is resistance
between 2.0k ohms and 5.0k ohms
Examine harness for
short to ground and
repair.
YES
Perform 5.8 WIGGLE TEST on steps
marked with a BOLD ASTERISK above to
locate intermittents. Repair as necessary.
4
NO
Replace
IAT sensor.
At some point in the flow chart you
may be instructed to jump directly
to a the box with the bold asterisk.
Disregard the asterisk (but not the
instruction box) if your normal progression
through the chart brings
you to this location.
Clear codes using speedometer self diagnostics.
See 5.6 SPEEDOMETER SELF DIAGNOSTICS.
Confirm proper operation with no check engine
lamp.
