A. WORK OUTLINE Reinstall the fuel pressure sensor to the fuel delivery pipe using the specified procedure. Failure to observe the instructions will cause looseness or deformation of the sensor, and may result in abnormal sensor outputs. The vehicle does not need to be lifted up. Conventional Tightening Procedure <New Tightening Procedure> Grind and clean the sensor installation surface of the delivery pipe. (Remove all foreign objects including minute particles that cannot be detected by the naked eye.) Tighten the sensor to the specified torque (44 N*m) Apply lubrication to the threads to maintain constant friction coefficient, and tighten the sensor to the specified torque. As a preparation for tightening the sensor to the specified angle, tighten the sensor until the sensor, delivery pipe and gasket are tightened without any gap, to a point just before the gasket undergoes plastic deformation. Tighten the sensor to the specified angle. By applying the angle controlled tightening method, the gasket is plastically deformed to the desired amount, ensuring proper sealing performance. 8
