Low Fuel Indicator Light

The PCM lights the low fuel indicator light and informs the driver that the fuel level is low.

The PCM calculates the gas quantity in the fuel tank by using the fuel pressure value detected by fuel tank pressure sensor and the fuel temperature value detected by fuel tank temperature sensor, and outputs the signal to the gauge assembly.

When the PCM detects a malfunction of the fuel tank pressure sensor and/or fuel tank temperature sensor, the PCM blinks the low fuel indicator light and causes the fuel gauge to read empty.

When the PCM detects a gas leak, the PCM blinks the low fuel indicator light and reduces the fuel meter to 0. After the engine is stopped while the low fuel indicator light is blinking for a gas leak, the engine will not start until the PCM is reset.
