  • 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.

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.
