  • Replacement of fuel pump assembly
  • Replacement of port fuel injector assembly
  • Replacement of fuel pressure sensor (fuel delivery pipe with sensor assembly)
  • 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.

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 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 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)

PROCEDURE

1. PRECAUTION

NOTICE:

After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

PRECAUTION PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL NOTICE: When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected. System Name See Procedure Lane Control System (for Gasoline Model)

 ECM Power Source Circuit

DESCRIPTION When the engine switch is turned on (IG), the battery voltage is applied to IGSW of the ECM. When the transistor in the MREL circuit operates, current flows from the battery to ground through the drive circuit of the EFI-MAIN NO. 1 relay, thus operating the relay which supplies power to
