REMOVAL

CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during port fuel injector assembly removal/installation are shown below.

Necessary Procedures After Parts Removed/Installed/Replaced

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Replacement of port fuel injector assembly Replacement of No. 2 fuel pressure sensor. Replacement of EGR valve assembly Gas leak from exhaust system is repaired	Inspection after repair	Poor idle, etc. Engine start function, etc.

CAUTION:

Never perform work on fuel system components near any possible ignition sources.
Vaporized fuel could ignite, resulting in a serious accident.

Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.
Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

NOTICE:

This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.
