Fuel Temperature Sensor Replacement Cost Estimate

When diagnosing the check engine light, the technician will need to connect a diagnostic scanner to the vehicle, read the trouble codes, and use that information coupled with classroom training and experience to identify the cause of failure. In some situations, the fuel temperature sensor will not be suspected except for the understanding that ambient temperature and fuel temperature readings are too far removed from one another. Once the fuel temperature sensor is suspected, the fuel temperature sensor readings and actual fuel temperature will be compared to note any significant differences.

Since the location of the fuel temperature sensor will be different for each make and model that uses this type of engine control sensor, the replacement procedure will vary, sometimes greatly. This may involve removing the sensor from the fuel tank, fuel rail, or fuel lines, so removal and installation may be a very quick and easy task, or it may be daunting.
