Test 7: Outside Temperature Display
Disconnect instrument cluster harness connector No. 1. See Figure . Measure outside air temperature. Measure resistance between terminals No. 1 and 2 at instrument cluster harness connector No. 2. Ensure resistance is as specified in table. See OUTSIDE TEMPERATURE DISPLAY TESTING table. If resistance is as specified, check electronic circuit board. If circuit board is okay, replace outside temperature display. If resistance is not as specified, check wiring. See WIRING DIAGRAMS . If wiring is okay, replace outside temperature sensor.
OUTSIDE TEMPERATURE DISPLAY TESTING
| Air Temperature °F (°C) | Resistance (Ohms) |
|---|---|
| -4 (-20) | 29,000 |
| 32 (0) | 9800 |
| 68 (20) | 3700 |
| 104 (40) | 1600 |
