AVENSIS REPAIR MANUAL (RM1018E)
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.

(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween each terminal.
Resistance:
Approx. 20
C (68

NOTICE:
In case of checking the water temperature sensor in the wa-
ter, be careful not to allow water to go into the terminals,
and after checking, wipe out the sensor.
4. INSPECT INJECTION OR SUPPLY PUMP ASSY
(a) Resistance inspection. (Fuel temperature sensor)
(1) Using an ohmmeter, measure the resistance be-
tween each terminal.
Resistance:
Approx. 20
