INSPECTION
1. INSPECT AND CLEAN FILTER IN EGR VACUUM MOD-
ULATOR

side (outward).
2. INSTALL VACUUM GAUGE
Using 3 - way connector, connect a vacuum gauge to the EGR
valve vacuum hose as shown in the illustration.
3. INSPECT SEATING OF EGR VALVE
Start the engine and check that the engine starts and runs at
idle.
4. INSPECT OPERATION VSV WITH COLD ENGINE
(a) The engine coolant temperature shold be below 45°C
(113°F).
(b) Check that the vacuum gauge indicates zero at 2,500
rpm.
5. INSPECT OPERATION OF VSV AND EGR VACUUM
MODULATOR WITH HOT ENGINE
(a) Warm up the engine to above 60°C (140°F).
(b) Check that the vacuum gauge indicates low vacuum at
2,500 rpm.
(c) Check that the vacuum gauge indicates zero at idle.
(d) Disconnect the vacuum hose from port R of the EGR vac-
uum modulator and connect port R directley to the intake
manifold with another hose.
(e) Check that the vacuum gauge indicates high vacuum at
2,500 rpm.
HINT:
As a large amount of exhaust gas enters, the will misfire slghtly.

(b) Apply vacuum directly to the EGR valve with the engine
idling.
(c) Check that the engine runs rough or dies.
(d) Reconnect the vacuum hoses to the proper locations.
HINT:
As exhaust gas is increasingly recirculated, the engine will start
to misfire.

tans to air flow.
If operation is not as specified, replace the EGR vacuum modu-
lator.

regulator plug the hose end.
(q) Measure the fuel pressure at idle.
Fuel pressure:

147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injector.
(t) After checking fuel pressure, disconnect the negative (-)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.
