Toyota Is recalling certain model year 2006-2009 Lexus Is and model year 2006-2007 Lexus gs vehicles. Due to insufficient tightening of the fuel pressure sensor connected to an engine fuel delivery pipe with nickel phosphorus plating, there Is a possibility that, over time, the pressure sensor could loosen. If loosening occurs, fuel could leak past a gasket used in the connection between the sensor and the pipe and through the threaded portion of the sensor.
Dealers will inspect for fuel leakage from the threaded portion of the fuel pressure sensor and if a fuel leak Is not confirmed, dealers will further tighten the fuel pressure sensor with the proper torque. If a fuel leak Is confirmed, the gasket between the sensor and the fuel deliver pipe will be replaced with a new one, and the sensor will be tightened with the proper torque. This service will be performed free of charge. The safety recall began on March 7, 2011. Owners may contact Toyota at 1-800-331-4331.
