Fuel Heater Temperature Sensor
WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect electrical connector from fuel heater temperature sensor. See Figure . Check for continuity between sensor connector terminals. If fuel temperature is greater than 80°F (26.7°C), there should be no continuity. If fuel temperature is less than 40°F (4.4°C), there should be continuity. If continuity is not as specified, replace sensor.
