IG "OFF". Disconnect IATS connector.
Measure resistance between signal and ground terminals of IATS connector after checking the temperature of IATS with GDS (Component Side)
Temp. (℃) | Resistance (kΩ) | Temp. (℃) | Resistance (kΩ) |
-20 (-4°F) | 13.8 ~ 16.0 | 60 (140°F) | 0.54 ~ 0.66 |
20 (68° F) | 2.31 ~ 2.56 | - | - |
Is the measured resistance within specification ?
