Intake Air Temperature (IAT) Sensor

NOTE: Sephia & Spectra, IAT sensor component testing not available from manufacturer. For IAT sensor system testing, see TEST P0112: IAT CIRCUIT LOW INPUT or TEST P0113: IAT CIRCUIT HIGH INPUT in SELF-DIAGNOSTICS - SEPHIA & SPECTRA article.

On Optima & Magentis (Canadian) 2.5L and Rio, disconnect IAT sensor 2-pin connector. Located in intake manifold. Measure resistance between IAT sensor terminals. Resistance should be 2.21-2.82 k/ohms at 68°F (20°C). Sportage, IAT sensor is located on air cleaner assembly. Disconnect IAT sensor 2-pin connector. Measure resistance between IAT sensor terminals. Resistance should be 2.21-2.69 k/ohms at 68°F (20°C). If resistance is not as specified, replace IAT sensor.
