- Disconnect Intake Air Temperature (IAT) sensor connector. Turn ignition on. Check voltage between ground and Gray/Red wire (Esteem and Vitara), Light Blue wire (Grand Vitara and XL-7) terminal of connector. If voltage is not 4-6 volts (4.5-5.5 on Grand Vitara and XL-7), check wiring harness for an open or short. If voltage is as specified, go to next step.
- Remove IAT sensor and place in container of water with a thermometer. Heat water to specified temperature and check resistance. See IAT SENSOR RESISTANCE SPECIFICATIONS table. See Fig 1 . Replace IAT sensor if resistance is not within specification.
