Fuel Level Sensor-PCM Input

FUEL LEVEL SENSOR-PCM INPUT

The fuel level sensor (fuel gauge sending unit) sends a variable voltage to the Powertrain Control Module (PCM) to indicate fuel level. The purpose of this feature is to prevent a false setting of misfire and fuel system monitor trouble codes if the fuel level is less than 15 percent of its rated capacity.

Refer to Fuel Gauge Sending Unit Description and Operation for additional information.
