Sedona EX V6-3.5L (2002)
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)
8. If the results of the measurements made in steps (6) and (7) are not within the standard value, use the table below to determine the probable cause,
and make the necessary repairs.
Condition / Probable Cause
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.
Condition / Probable Cause
10. Reduce the fuel pressure in the fuel line.
11. Disconnect the high pressure hose and remove the fuel pressure gauge.
CAUTION: Cover the pipe connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.
12. Install a new O-ring at the groove in the end of the high-pressure hose.
13. Connect the high pressure fuel hose to the delivery pipe, and tighten the screws to the specified torque.
Tightening torque
High pressure fuel hose to delivery pipe:
3 - 4 N.m 30 - 40 kg.cm, 2.2 - 3 lb.ft
