Fuel Tank Pressure Sensor (CNG): Testing and Inspection

Low Fuel Indicator Light

Description
The low fuel indicator light turns on when the fuel level is low.
The low fuel indicator light blinks when a problem is detected with the fuel tank pressure sensor or the fuel tank temperature sensor.

NOTE: If a fuel leak is detected, the fuel pressure regulator shut-off solenoid valve/fuel tank internal solenoid valve will not reopen until the PCM is reset.
