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 fuel pressure sensor 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
*1: When performing learning using the Techstream. Click here
Battery terminal is disconnected/reconnected	Perform steering sensor zero point calibration	Lane Departure Alert System (w/ Steering Control)
		Pre-collision System
		Intelligent Clearance Sonar System*1
		Lighting System (for Gasoline Model with Cornering Light)
	Memorize steering angle neutral point	Parking Assist Monitor System
	Memorize steering angle neutral point	Panoramic View Monitor System
Replacement of fuel pressure sensor 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.
To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.

NOTICE:

After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System)
After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)
This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.

5. REMOVE FUEL PRESSURE SENSOR

CAUTION:

To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.

(a) Disconnect the fuel pressure sensor connector.

(b) Using an 8 mm socket wrench, remove the 2 bolts, fuel pressure sensor and No. 1 fuel pressure sensor holder from the fuel delivery pipe.

NOTICE:

Pull and remove the fuel pressure sensor in a straight line to avoid damaging the seal surface of the fuel delivery pipe O-ring.
After removing the fuel pressure sensor, remove any O-ring and fuel injector back-up rings remaining on the fuel delivery pipe side.
