d. Tighten fuel pressure sensor.

CAUTION:

• Before tightening fuel pressure sensor, securely install a hexagon tool. 

• Never use impact applied fuel pressure sensor or gasket, such as dropped.

e. Tighten fuel rail pressure sensor again by using angle wrench [SST: KV10112100] and torque wrench.

(Angle tightening)

CAUTION:

• To check tightening angle, use angle wrench [SST: KV10112100]. Never judge the angle by visual

inspection.

• The torque value for the angle tightening must be 90 N·m (9.2 kg-m, 66 ft-lb) or less.

• If torque value reaches 90 N·m (9.2 kg-m, 66 ft-lb), then replace fuel rail pressure sensor with a

new one.

2. Install seal ring to fuel injector as per the following:

CAUTION:

• Handle seal ring with bare hands. Never wear gloves.

• Never apply engine oil to seal ring.

• Never clean seal ring with solvent.

a. Install an injector seal drift set [SST: KV101197S0 (—)] (A) to
