IAT Sensor Resistance Inspection

WARNING: This page is about a different car, the 2004 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the MAF/IAT sensor connector.
Measure the resistance between MAF/IAT sensor terminals A and F using an ohmmeter.
- If not as specified, replace the MAF/IAT sensor.
- If the IAT sensor is okay, but the IAT PID is out of specification, perform IAT Sensor Circuit Open/Short Inspection .
