In-Car Temperature Sensor Testing
WARNING: This page is about a different car, the 1998 Acura 3.2TL. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
To avoid damage to sensor, use an ohmmeter with a measuring current of one milliamp or less.
Remove climate control unit. Remove sensor from dashboard. Measure resistance across sensor connector terminals at specified temperatures. See IN-CAR TEMPERATURE SENSOR RESISTANCE table. If resistance is not as specified, replace sensor.
IN-CAR TEMPERATURE SENSOR RESISTANCE
| Temperature °F (°C) | Ohms |
|---|---|
| 32 (0) | 6600 |
| 50 (10) | 4100 |
| 68 (20) | 2500 |
| 86 (30) | 1700 |
| 104 (40) | 1100 |
