5. INSPECT ENGINE COOLANT TEMPERA TURE
SENSOR
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-tween terminals.
Resistance:
2.32 to 2.59 k at 20
C (68
F)
0.310 to 0.326 k at 80
C (176
F)
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.
6. INSPECT KNOCK SENSOR
(a) Using an ohmmeter, measure the resistance between ter- minals.
Resistance: 120 to 280 k at 20
C (68
F)
HINT:
If the resistance is not specified, replace the sensor.
7. INSPECT EFI RELAY
(a) Inspect the relay continuity. (1) Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
Specified condition: Continuity
(2) Check that there is no continuity between terminals 3 and 5.
Specified condition: No continuity
(b) Inspect the relay operation. (1) Apply battery voltage across terminals 1 and 2.
(2) Using an ohmmeter, check that there is continuitybetween terminals 3 and 5.
Specified condition: Continuity

19.INSTALL FUEL INLET PIPE SUB±ASSY
NOTICE:

In case of having the common rail replaced, must re-
place fuel inlet pipe, too.

When assembling the pipe, perform the operation
with the engine cold under room temperature.
(a)Temporarily install the fuel inlet pipe.
(b)Using SST, tighten the nut of the fuel inlet pipe to the com-
mon rail side.

or if it can not be installed properly, replace the used pipe
with a new pipe.
(c)Using SST, tighten the nut of the fuel inlet pipe to the injec-
tion pump side.

EMISSION CONTROL EGR SYSTEM (1CD±FTV)

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 s\
moke 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 m\
eter (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 andthe 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 i\
n 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.
