Sorento V6-3.5L (2004)
6. Disconnect the vacuum hose from the pressure regulator and plug the hose end. Measure the fuel pressure at idle.
Standard value: 320 - 340 kPa (3.26 - 3.47 kg/sq.cm, 46 - 49 psi)
7. Measure the fuel pressure when the vacuum hose is connected to the pressure regulator (while engine is running).
Standard value: Approx. 270 kPa (2.75 kg/sq.cm, 39 psi)
Condition/Probable Cause
8. If the results of the measurements made in steps (6) and (7) are not within the standard value, use the table to determine the probable cause, and
make the necessary repairs.
9. Stop the engine and check for a change in the fuel pressure gauge reading, which should hold for approximately 5 minutes. If the gauge indication
drops, observe the rate of drop. Determine and remove the causes according to the table.
10. Reduce the fuel pressure in the fuel line.
11. Disconnect the high pressure hose and remove the fuel pressure gauge.
