INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loose connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
Look for deformation, cracks or fuel leakage.
3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged.
If necessary, repair or replace the cap.
4. REMOVE CHARCOAL CANISTER
5. VISUALLY INSPECT CHARCOAL CANISTER
Look for cracks or damage.
6. CHECK FOR CLOGGED FILTER AND STUCK CHECK
VA LV E
(a) Using low pressure compressed air (4.71 kPa (48 gf/cm
2,
0.68 psi)), blow into port C and check that air flows without
resistance from the other ports.

(b) Blow air (4.71 kPa (48 gf/cm2, 0.68 psi)) into port A, and
check that air does not flow from the other ports.
(c) Blow air (4.71 kPa (48 gf/cm
2, 0.68 psi)) into port B, and
check that air does not flow from the other ports.
If operation is not as specified, replace the charcoal canister.
7. CLEAN FILTER IN CANISTER
Clean the filter by blowing 294 kPa (3 kgf/cm
2, 43 psi) of com-
pressed air into port C while holding port A and B closed.
NOTICE:

Do not attempt to wash the canister.

No activated carbon should come out.
8. REINSTALL CHARCOAL CANISTER
9. INSPECT VSV FOR EVAP
(See page SF-71)
10. REMOVE CHECK VALVE
11. INSPECT CHECK VALVE
(a) Check that air flows from the blue port to the black port.
(b) Check that air does not flow from the black port to the blue
port.
If operation is not as specified, replace the check valve.
12. REINSTALL CHECK VALVE
HINT:
Install the check valve with the black port facing the purge port
side of the throttle body.

INSPECTION
1. CHECK AND CLEAN FILTER IN EGR VACUUM
MODULATOR
(a) Remove the cap and 2 filters.
(b) Check the filter for contamination or damage.
(c) Using compressed air, clean the filter.
(d) Reinstall the 2 filters and cap.
HINT:
Install the filter with the coarser surface facing the atmospheric
side (outward).
2. INSTALL VACUUM GAUGE
Using a 3-way connector, connect a vacuum gauge to the hose
between the EGR valve and EGR vacuum modulator.
3. INSPECT SEATING OF EGR VALVE
Start the engine and check that the engine starts and runs at
idle.
4. INSPECT VSV OPERATION WITH COLD ENGINE
(a) M/T
The coolant temperature should be below 50°C (122°F).
(1) Start the engine and check idling.
(2) When idling with the lever shifting in the N position,
press accelerator pedal slowly to hold the engine
speed at 1,600 - 1,800 rpm.
(3) Check that the vacuum gauge indicates zero.
(b) A/T
The coolant temperature should be below 65°C (149°F).
(1) Chock the 4 wheels.
(2) Fully apply the parking brake.
(3) Connect a tachometer to the engine.
(4) Start the engine and check idle.
(5) Keep your foot pressed firmly on the brake pedal.
(6) Shift into the D position. Press the accelerator pedal
slowly to hold the engine speed at 1,600 - 1,800
rpm.
(7) Check that the vacuum gauge indicates zero.
5. INSPECT VSV OPERATION WITH HOT ENGINE
(a) M/T
Warm up the engine. The coolant temperature in 50°C
(122°F) or more.
(1) When idling with the lever shifting in the N position,
press accelerator pedal slowly to hold the engine
speed at 1,600 - 1,800 rpm.
(2) Check that the vacuum gauge indicates low vacu-
um momentarily.
