Disconnect IATS connector
Measure resistance between terminals 3 and 4 of the sensor connector(Component side).
Specification
Temp.(°C) | Temp.(°F) | Resistance(kΩ) | Temp.(°C) | Temp.(°F) | Resistance(kΩ) |
-10 | 14 | 8.5~9.7 | 20 | 68 | 2.3~2.5 |
0 | 32 | 5.4~6.1 | 30 | 86 | 1.6~1.7 |
10 | 50 | 3.5~3.9 | 80 | 176 | Approx. 0.3 |
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 IATS for contamination, deterioration, or damage. Substitute with a known-good IATS and check for proper operation. If the problem is corrected, replace IATS and then go to "Verification of Vehicle Repair" procedure
