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
Battery terminal is disconnected/reconnected	Perform steering sensor zero point calibration	Lane Tracing Assist System
	Perform steering sensor zero point calibration	Pre-collision System
	Memorize steering angle neutral point	Parking Assist Monitor System
	Memorize steering angle neutral point	Panoramic View Monitor System
Replacement of port fuel injector assembly Replacement of fuel pressure sensor (fuel delivery pipe with sensor sub-assembly) Replacement of throttle body with motor assembly Cleaning the deposits from the throttle body with motor assembly 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.

8. REMOVE FUEL DELIVERY PIPE WITH SENSOR SUB-ASSEMBLY

(a) Remove the 2 bolts and fuel delivery pipe with sensor sub-assembly with the 4 port fuel injector assemblies from the cylinder head sub-assembly.

NOTICE:

If fuel intrudes into the combustion chamber, there may be adverse affects to the engine main body.
Be careful not to drop the port fuel injector assemblies when removing the fuel delivery pipe with sensor assembly.

9. REMOVE NO. 1 DELIVERY PIPE SPACER

(a) Remove the 2 No. 1 delivery pipe spacers from the cylinder head sub-assembly.

10. REMOVE INJECTOR VIBRATION INSULATOR

(a) Remove the 4 injector vibration insulators from the cylinder head sub-assembly.

11. REMOVE NO. 5 ENGINE WIRE

(a) Disconnect the 4 port fuel injector assembly connectors and fuel pressure sensor connector.

(b) Disengage the 2 clamps to remove the No. 5 engine wire from the fuel delivery pipe with sensor sub-assembly.

12. REMOVE PORT FUEL INJECTOR ASSEMBLY

(a) Pull the 4 port fuel injector assemblies out of the fuel delivery pipe with sensor sub-assembly.

(b) Remove the O-ring from each port fuel injector assembly.

(c) Attach a tag or label with the corresponding cylinder number to each port fuel injector assembly so that they can be installed to their original locations.

NOTICE:

Cover the port fuel injector assemblies with plastic bags to prevent damage and contamination.
