Measure resistance between terminals 1 and 2 of the sensor connector(to IAT sensor).
Specification : (at 20℃(68℉))
Temperature | Resistance(㏀) |
-20℃(-4℉) | Approx. 14.26 ~ 16.02 |
20℃(68℉) | Approx. 2.22 ~ 2.82 |

Is IAT sensor data near the specified value?
YES
Thoroughly check connectors for loose or poor connections, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure
NO
Test with a new IAT sensor and check for proper operation. If problem is corrected, replace IAT sensor. Go to "Verification of Vehicle Repair" procedure
