fuel delivery pipe and the fuel pump when installing the fuel
pipe No.1.
(c) Tighten the nut by hand to attach the fuel pipe sub±assy
No. 1 to the fuel pump assy.
(d) In order to secure the fuel pipe sub±assy No. 1 to the fuel
delivery pipe sub±assy, tighten the 2 bolts to the specified
torque.

ASSY
(a) Install the fuel pulsation damper assy to the fuel pump
assy after fitting new 2 gaskets and fuel tube sub±assy
between those assys.
(b) Using SST, install the fuel pressure pulsation damper
assy to the fuel pump assy.

2. INSPECT VENTILATION VALVE SUB±ASSY
(a) Install clean hose to the PCV valve.
(b) Inspect the PCV valve operation.
(1) Blow air into the cylinder head side, and check that
air passes through easily.
CAUTION:
Do not suck air through the valve. If contains petroleum
substances and is harmful.
(2) Blow air into the intake manifold side, and check
that air passes through with difficulty.
If operation is not as specified, replace the PCV valve.
(c) Remove clean hose from the PCV valve.
3. INSPECT FUEL TANK CAP ASSY
(a) Visually check if the cap or gasket is deformed or dam-
aged.
If necessary, repair or replace the cap.

1. INSPECT AIR±FUEL RATIO COMPENSATION SYS-
TEM
HINT:
You can also check the system by choosing ºDATA MONITOR/
O
2 SENSOR OUTPUT VOLTAGEº on the monitor of the hand±
held tester.
(a) Connect the hand±held tester to the following each pair
of the ECM terminals:
(1) Terminals 21 (OX1B) and 1 (E1)
(2) Terminals 22 (OX1A) and 1 (E1)
(3) Terminals 23 (OX2A) and 1 (E1)
(4) Terminals 29 (OX2B) and 1 (E1)
CAUTION:
Connect test leads from the back side of the connector with
the ECU connected.
(b) Warm up the heated oxygen sensor with the engine
speed at 2,500 rpm for approximately 2 minutes.
(c) Confirm that the voltage output varies between 0V to 1V
with the engine speed at 2,500 rpm.
OK:
The voltage output varies more than 8 times in 10 se-
conds.
CAUTION:

Perform the check immediately after the warming up.

If the voltage variation could not be verified, warm up
the heated oxygen sensor again.
2. INSPECT FUEL CUT OFF RPM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for injector operating sounds.
(c) Check that the injector operating sounds stops momentarily and then resumes that when the throttle
lever is released.
3. INSPECT EVAPORATIVE EMISSION CONTROL SYS-
TEM
(a) After starting the engine, disconnect the vacuum hose
shown in the illustration.
(b) Check if vacuum occurs at the VSV port when choosing
ºACTIVE TESTº and ºPURGE VSVº according to the dis-
play on hand±held tester.
(c) Finish ºACTIVE TESTº, then reconnect the vacuum hose.
(d) After entering to ºECU DATA MONITORº on the hand±
held tester, choose ºPURGE VSVº to check the operation
of the purge VSV.
(e) After driving the vehicle with a warm engine, confirm that
the VSV turns from off on to.

If the resistance is not as specified, replace the VSV.
(b) Inspect the VSV for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect the VSV operation.
(1) Check that air flows with a little difficulty from port E
to port F.
(2) Apply battery voltage across the terminals.
(3) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
