Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Intake Air Temperature (IAT) Sensor: MPV
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.
| Temperature - °F (°C) | Ohms |
|---|---|
| 50 (10) | 3300-4100 |
| 68 (20) | 2200-2700 |
| 86 (30) | 1400-1900 |
