RAM 3500 Van V8-5.2L CNG VIN T (1996)
Fuel Temperature Sensor: Testing and Inspection
1. Remove engine cover.
2. Remove air filter housing.
3. Disconnect wire harness connector from sensor.
Fuel Temperature Sensor Resistance
4. Test resistance of sensor with an input impedance (digital) volt-ohmmeter. The resistance should be less than 4000 ohms with the engine at
operating temperature. Refer to Fuel Temperature Sensor resistance chart. Replace sensor if it is not within range of resistance specified in chart.
5. Test resistance of wire harness. Do this between the powertrain control module (PCM) wire harness connector and sensor connector. Repair wire
harness as necessary if resistance is greater than 1 ohm.
6. Install air filter housing.
7. Install engine cover.
