Potential Fuel Leak

Due to the remnants of anti-corrosion plating, a fuel leak may develop from where the fuel pressure sensor is attached to the fuel delivery pipe. Any fuel leak always increases the risk of a fire. Dealers will clean and reseal the area of the fuel pressure sensor to correct this concern.

 

A Fuel Leak Can Develop at the Fuel Pressure Sensor Connection

The fuel pressure sensor monitors fuel pressure for optimum engine performance and emission controls. Lexus has found that some of these sensors can loosen from the fuel line, which may cause the sealing gasket to leak fuel. To prevent this from occurring in the future, your Lexus dealer will ensure that these sensors are properly fastened. No schedule of owner notification is available at this time.
