1) Remove the IAT sensor.
Refer to “IAT Sensor Removal and Installation”
(Page 1C-10).
2) Immerse temperature sensing part of IAT sensor in
water.
3) Measure resistance between sensor terminals while
heating water gradually.
4) If measured resistance does not change in the
proportion indicated, replace sensor.
