Pressure Control Solenoid Valve Assembly

EMISSION CONTROL (AUX. EMISSION CONTROL DEVICES)

8. Pressure Control Solenoid

Valve Assembly

A: REMOVAL

1) Disconnect the ground cable from battery.

2) Lift up the vehicle.

3) Disconnect the connector (A) and evaporation

hose (B) from the pressure control solenoid valve

assembly.

4) Remove the nut (C) securing the bracket to the

fuel tank and remove the pressure control solenoid

valve assembly.

B: INSTALLATION

Install in the reverse order of removal.
Tightening torque:

7.35 N·m (0.7 kgf-m, 5.4 ft-lb)

C: INSPECTION

1. PRESSURE CONTROL SOLENOID

VALVE ASSEMBLY

1) Check that the pressure control solenoid valve

assembly has no deformation, cracks or other dam-

ages.

2) Check the resistance between the pressure con-

trol solenoid valve assembly terminals.

3) Connect the Mighty Vac to fuel tank side of the

pressure control solenoid valve assembly.

4) Using the Mighty Vac, generate the positive

pressure. Check that the Mighty Vac gauge needle

rises at the pressure (0.55 — 1.55 kPa (0.006 —

0.016 kgf/cm

2

, 0.08 — 0.23 psi)) then lowers.

5) Using the Mighty Vac, generate the negative

pressure. Check that the Mighty Vac gauge needle

does not rise.

2. OTHER INSPECTIONS

Check that the evaporation hose has no cracks,

damage or loose part.
