DTCP0462
Circuit / System Description
The fuel level sensor measures fuel level changes within the fuel tank and changes resistance based on fuel level. The powertrain control module (PCM) monitors changes in the resistance of the sensor to determine fuel level. When the fuel tank is full, the sensor resistance is high, and the PCM senses high signal voltage. When the fuel tank is empty, the sensor resistance is low, and the PCM senses a low signal voltage. The PCM uses inputs from the fuel level sensor to calculate the total fuel remaining in the fuel tank. This information is then sent to the Instrument via the Class 2 serial data circuit and the powertrain interface module (PIM). When the PCM senses a signal voltage lower than the normal operating range of the sensor, this DTC sets.
