(d) Disconnect the vacuum hose from R port of the EGR
vacuum modulator and connect R port directly to the
intake manifold with another hose.
(e) Check that the vacuum gauge indicates high vacuum
at 3,500 rpm.
HINT: As a large amount of EGR gas enters, the
engine will misfire slightly.
(f) Disconnect the vacuum gauge and reconnect the
vacuum hoses to the proper locations.
2. PREPARATION
Disconnect the vacuum hose from the EGR valve and
using a three–way union, connect a vacuum gauge to
it.
3. CHECK SEATING OF EGR VALVE
Start the engine and check that the engine starts and
runs at idle.
5. CHECK VSV AND EGR VACUUM MODULATOR
WITH WARM ENGINE
(a) Warm up the engine.
(b) Check that the vacuum gauge indicates zero at idle.
(c) Check that the vacuum gauge indicates low vacuum
at 3,500 rpm.
EGR SYSTEM INSPECTION
1. CHECK AND CLEAN FILTER !N EGR VACUUM
MODULATOR
(a) Check the filter for contamination or damage.
(b) Using compressed air, clean the filter.
4. CHECK VSV WITH COLD ENGINE
(a) The engine coolant temperature should be below
48
C(118
F).
(b) Check that the vacuum gauge indicates zero at 3,500
rpm.
