REMOVAL

1. PRECAUTION
2. DISCHARGE FUEL SYSTEM PRESSURE
a. Discharge fuel system pressure.

3. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

NOTE: After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.

INSTALLATION

1. INSTALL FUEL PRESSURE SENSOR
a. Install a new gasket to the fuel pressure sensor.




b. Using SST, install the fuel pressure sensor to the No.1 delivery pipe.

SST 09922-10010

Torque:
without SST
44 N.m (449 kgf.cm, 32 ft.lbf)
with SST
40 N.m (409 kgf.cm, 30 ft.lbf)

NOTE:
- Do not apply oil to threads of the pressure sensor and delivery pipe.
- Do not allow foreign matter to enter the pipe during the installation.

HINT:
- Use a torque wrench with a fulcrum length of 300 mm (11.81 in).
- Make sure SST and wrench are connected in a straight line.




c. Connect the connector.

2. INSTALL NO.2 ENGINE COVER SUB-ASSEMBLY




a. Install the engine cover to the engine.
