NR Series FUEL FUEL PRESSURE SENSOR 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 (fuel delivery pipe) 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 fuel injector assembly · Replacement of fuel pump assembly · Replacement of fuel pressure sensor (fuel delivery pipe) · Replacement of throttle body with motor assembly · Cleaning the deposits from the throttle body with motor assembly	Inspection after repair	· Poor idle, etc. · Engine start function, etc.	(201906,999999,_51,_080777,_0393969,RM100000001I1RE,)

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 ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.; Click hereGeneral>SETUP>WHEN DISCONNECTING OR RECONNECTING BATTERY TERMINAL>BEFORE DISCONNECTING BATTERY202304,202502,_V1,_143216,_0598315,RM100000002B3MI,202502,999999,_V1,_143216,_0598315,RM100000002RP07,

HINT:

When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

Hide Display 23839A 2.REMOVE NO. 1 FUEL PIPE PLUG

Secure the fuel delivery pipe in a vise between aluminum plates.

NOTICE:: Do not overtighten the vise.

Using a 5 mm hexagon socket wrench, remove the 2 bolts, gasket and No. 1 fuel pipe plug from the fuel delivery pipe.

Remove the dust cap sub-assembly from the No. 1 fuel pipe plug.

Remove the O-ring, No. 1 fuel injector back-up ring, No. 2 fuel injector back-up ring and No. 3 fuel injector back-up ring from the No. 1 fuel pipe plug.

Remove the fuel delivery pipe from the vise.
