Lumina APV V6-191 3.1L (1990)
Temperature Gauge: Testing and Inspection
Gauge Reads High
1.
Remove lead at sensor, measure resistance using a suitable ohmmeter.
2.
At 40°C (104 °F) resistance should be approximately 1200-1350 ohms, and at 125°C (257 °F) resistance should be approximately 53-55ohms.
3.
If not within specifications, replace sensor.
4.
Disconnect lead at sensor and gauge, check for a high resistance using a suitable ohmmeter. Repair wiring if necessary.
