P0168 BUICK Description
The Fuel Temperature Sensor is a thermistor type sensor. The Powertrain Control Module (PCM) supplies 5 volts and a ground circuit to the sensor. When the PCM detects a Fuel Temperature Sensor above a pre-determined value, no Malfunction Indicator Lamp (MIL) sets. A fuel cooler located in front of the fuel tank is used to help keep the fuel temperature at an acceptable limit.
