2. Check fuel pressure

  1. Prepare for inspection.
  1.  Purchase a new fuel tube, and take out the fuel tube connector from its tube.

Hint

: part no. 239010D010

  1.  work for prevent gasoline from spilling out.

     

  2.  disconnect the efi fuel pipe clamp.
  3.  disconnect the fuel tube from the fuel main tube.

     

  1. Install sst (pressure gauge) as shown in the illustration by using the sst and fuel tube connector.

    Sst 0926841047 (9046713001, 9533608070), 0926845014 (0926841200, 0926841220, 0926841250, 9046713001)

  2.  wipe off any splattered gasoline.
  3. ) start the engine.
  4.  measure the fuel pressure at idle.

    Fuel pressure: 304 343 kpa (3.1 3.5 Kgfvcm2, 44 50 psi)

  5.  stop the engine.
  6.  check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.

    Fuel pressure:
    147 kpa (1.5 Kgfvcm2, 21 psi) or more

If pressure is not as specified, check the fuel pump, pressure regulator and/or injectors.

  1.  after checking fuel pressure, disconnect the negative () terminal cable from the battery and carefully, remove the sst and fuel tube connector to prevent gasoline from the splashing.
  2.  reconnect the fuel tube to fuel main tube.

Diagnostic trouble code chart
Hint: when the srs warning light remains lit up and the dtc is the normal code, this means a voltage source drops. This malfunction is not stored in memory by the airbag sensor assy center and if the power source voltage returns to normal, the srs warning light will autom ...

Circuit description
The side squib (lh) circuit consists of the airbag sensor assy center and front seat airbag assy (lh). It causes the srs to deploy when the srs deployment conditions are satisfied. Dtc b0115/47 is recorded when a short is detected in the side squib (lh) circuit. Wiring diagram ...
