1. Let engine cool.
2. Disconnect the water temperature indicator sender unit connector.
3. Measure the resistance between the terminal of the water temperature indicator sender unit and ground.
4. Start the engine.
5. Verify the resistances in the chart as the engine warms up.

Coolant Temperature Resistance
°C (°F) (Ohms)
75 (167) 179-219
100 (212) 60-72

6. If the resistance is not as specified, replace the water temperature indicator sender unit. If the resistance is OK, return to the Pinpoint Tests.
