Air Temperature Sensor: Toyota
Disconnect air flow meter multi-pin connector and record ambient air temperature. Connect ohmmeter leads to terminals E2 and THA on potentiometer connector. Ohmmeter readings should be as follows, if not, replace temperature sensor and air flow meter as an assembly.
Temperature/Resistance Relationship
| Temperature | Resistance (Ohms) |
|---|---|
| -4°F (-20°C) | 10, 000-20, 000 |
| 32°F (0°C) | 4, 000-7, 000 |
| 68°F (20°C) | 2, 000-3, 000 |
| 104°F (40°C) | 900-1, 300 |
