WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
This DTC indicates that the vehicle ran out of fuel. If the ECM receives the fuel low level signal from the combination meter sub-assembly (meter ECU) and the DTC detection conditions of either DTC P3190 or P3191 are met while the power switch is on (IG) or the engine is operating, the ECM stores this DTC.
