EGR SYSTEM (1CD±FTV)
ON±VEHICLE INSPECTION
HINT:
In a malfunction where the EGR system is always on, black smoke or white smoke may be emitted from the
exhaust pipe. If this occurs, inspect the EGR system as well.
1. INSPECT SEATING OF EGR VALVE
(a) Start the engine and check that it starts and runs at idle.
2. INSPECT HOT ENGINE CONDITION (WHEN USING HAND±HELD TESTER)
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and run it at idle.
(c) Select the ACTIVE TEST mode on the hand±held tester.
HINT:
Refer to the hand±held tester operator's manual for further details.
(d) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(e) Check that the AFM reading is 5
ega
8 g/s with the engine idling.
(f) Operate the EGR valve with a hand±held tester. Regulate the valve opening angle to 0, and check that
the AFM reading is 11
ega
17 g/s..
If the AFM reading is out of range in either (e) or (f), replace the EGR valve.
If the AFM is out of range in both (e) and (f), replace the air flow meter (air cleaner) and check the EGR valve
operation again.
3. INSPECT HOT ENGINE CONDITION (WHEN NOT USING HAND±HELD TESTER)
(a) Install the vacuum gauge.
(1) Using a 3±way connector, connect a vacuum gauge to the hose between the intake manifold and
the turbo pressure sensor.
(b) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(c) Check that the vacuum gauge indicates about more than 2.5 kPa (19 mmHg 0.7 in Hg).
(d) Stop the engine (IG OFF), remove the EGR valve connector, restart the engine, and check that load
under idling is less than 2.5 kPa (19 mmHg 0.7 in Hg).
If the load pressure exceeds the above value, replace the EGR valve.

ON±VEHICLE INSPECTION
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 terminals 21 (OX1B) and
7 (E1) and to terminals 29 (OX2B) and 7 (E1) of the ECM.
CAUTION:
Connect test leads from the back side of the connector with
the ECM 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 injector operating sounds stops momentarily and then resumes 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 to on.

(a) Check for cracks, leak or damage.
HINT:
Separation of the engine oil dipstick, oil filler cap, PCV hose,
etc. may cause the engine to run improperly. Disconnection,
looseness or cracks in the parts of the air induction system be-
tween the throttle body and cylinder head will allow air suction
and cause the engine to run improperly.
