Measure resistance between terminals 1 and 2 of the IAT sensor connector(Component side).
Specification :
Temperature | Resistance(kΩ) |
20℃(68℉) | Approx. 2.22 ~ 2.82 |
40℃(104℉) | Approx. 1.06 ~ 1.31 |
80℃(176℉) | Approx. 0.29 ~ 0.36 |
Is resistance within the specification?
YES
▶ Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
NO
▶ Check IAT sensor for contamination, deterioration, or damage. Substitute with a known-good IAT sensor and check for proper operation. If the problem is corrected, replace IAT sensor and then go to "Verification of Vehicle Repair" procedure.
