Fuel Temperature Sensor

Disconnect fuel temperature sensor connector. Measure resistance between sensor terminal and ground. Resistance should be 2100-2900 ohms at 68°F (20°C), and 300-330 ohms at 176°F (80°C). Check sensor voltage values against values in FUEL TEMPERATURE SENSOR VOLTAGE TEST table. Replace sensor if values are not as specified.
