IS 350 V6-3.5L (2GR-FSE) (2006)
V. Background
Due to insufficient tightening of the fuel pressure sensor connected to certain engine fuel delivery pipes (those 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 pipe and through the threaded portion of the sensor.
