Intake Air Temperature Sensor

WARNING: This page is about a different car, the 2003 Mazda Tribute, 2003 Mazda B4000, 2003 Mazda B3000, and 2003 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: IAT sensor is part of Mass Airflow (MAF) sensor assembly.

Intake Air Temperature (IAT) sensor uses a 5 volt reference voltage during engine operation. To check IAT signal voltage, backprobe between signal terminal and ground with engine running. To check sensor resistance, disconnect sensor and measure resistance between sensor terminals. For specifications, see ENGINE COOLANT & INTAKE AIR TEMPERATURE SENSOR SPECIFICATIONS  table. For additional diagnostic testing, refer appropriate SELF-DIAGNOSTICS article.
