Intake Air Temperature (IAT) Sensor: MPV
WARNING: This page is about a different car, the 2001 Mazda Protege, 2001 Mazda Millenia, 2001 Mazda MX-5 Miata, 2001 Mazda MPV, and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
IAT sensor is part of Mass Airflow (MAF) sensor. Disconnect MAF sensor connector. Using ohmmeter, measure resistance between MAF sensor terminals "A" and "F", located at each end of connector. See IAT SENSOR RESISTANCE SPECIFICATIONS (MPV) table. If resistance is not as specified, replace MAF sensor. Check for open or short on wiring between IAT sensor and PCM. Repair as necessary.
IAT SENSOR RESISTANCE (MPV)
