Low Fuel Indicator

The PCM turns the low fuel indicator on to inform the driver that the fuel level is low.

The PCM calculates the gas quantity in the fuel tank by using the fuel pressure valve detected by the fuel tank pressure (FTP) sensor and the fuel temperature detected by the fuel tank temperature (FTT) sensor, and outputs a calculated signal to the gauge assembly.

When the PCM detects a malfunction of the FTP sensor, FTT sensor and/or fuel pressure regulator switch, the PCM causes the low fuel indicator to blink and the fuel gauge to read empty.

When the PCM detects a fuel leak, the PCM turns the low fuel indicator on and reduces the fuel meter to 0.

If the low fuel indicator is blinking, the vehicle will not start (see LOW FUEL INDICATOR TROUBLESHOOTING ).
