Test 13: Air Temperature Sensor
Check electrical connections on airflow meter. Using volt/ohmmeter, check resistance between airflow meter terminals that connect to Gray/Violet and Gray/Blue wires. Compare with table. See AIR TEMPERATURE SENSOR RESISTANCE chart. If values are incorrect, replace airflow meter.
| Air Temperature °F (°C) | Ohms |
|---|---|
| 14 (-10) | 8260-10,560 |
| 66-70 (19-21) | 2280-2720 |
| 120-124 (49-51) | 760-910 |
