If the fuel injector amount exceeds 570 g {20.1 oz}/stroke after receiving a signal from the instrument cluster that the remaining fuel level is low, the PCM determines that the fuel level is low.

• Fuel gauge sender unit malfunction
• Communication error between instrument cluster and PCM
• PCM malfunction
