HINT:
In the condition that the fuel fuel is full, as the float value of the
fill check valve is closed and has no ventilation, it is necessary
to check the fuel amount (volume).
(d) Check if there is any struck in the vent line hose and EVAP
line hose.
If there is no stuck in hoses, replace the fuel cutoff valve and fill
check valve.
(e) Reconnect the purge line hose and EVAP line hose to the
charcoal canister.
7. CHECK AIR INLET LINE
(a) Disconnect the air inlet line hose from the charcoal canis-
ter.
(b) Check that there is ventilation in the air inlet line.
(c) Reconnect the air inlet line hose to the charcoal canister.
8. REMOVE CHARCOAL CANISTER ASSEMBLY
(a) Disconnect the VSV connector.
(b) Disconnect the vapor pressure sensor connector.
(c) Disconnect the purge line hose, EVAP line hose and air
inlet line hose from the charcoal canister.
(d) Disconnect the vent line hose from the charcoal canister.
(1) Push the connector deep inside.
(2) Pinch portion A.
(3) Pull out the connector.
(e) Remove the 2 charcoal canister mounting bolts.
(f) Remove the vapor pressure sensor mounting bolt.
(g) Remove the charcoal canister assembly.
9. INSPECT CHARCOAL CANISTER
(a) Visually check the charcoal canister for cracks or dam-
age.
(b) Inspect the charcoal canister operation.
(1) Plug the vent port with a cap.
(2) While holding the purge port closed, blow air (1.76
kPa, 18 gf/cm
2, 0.26 psi) into the EVAP port and
check that air flows from the air drain port.

(3) While holding the purge port and the air drain port
closed, blow air (1.76 kPa, 18 gf/cm
2, 0.26 psi) into
the EVAP port and check that air does not flow from
the air inlet port.
(4) Apply vacuum (3.43 kPa, 25.7 mmHg, 1.01 in.Hg)
to the purge port, check that the vacuum does not
decrease when the air inlet port is closed, and
check that the vacuum decreases when the air inlet
port is released.
(5) While holding the air inlet port closed, apply vacuum
(3.43 kPa, 25.7 mmHg, 1.01 in.Hg) to the EVAP port
and check that air flows into the purge port.
If operation is not as specified, replace the charcoal canister.
(6) Remove the cap from the vent port.

INSPECTION
1. INSPECT EGR SYSTEM (See page DI±358)
2. INSPECT EGR VALVE POSITION SENSOR
(a) Inspect the resistance of the EGR valve position sensor.
(1) Disconnect the EGR valve position sensor connec-
tor.
(2) Using an ohmmeter, measure the resistance be-
tween the terminals VC and E2.
Resistance: 1.5 ± 4.3 kW
If the resistance is not as specified, replace the EGR valve posi-
tion sensor.
(3) Reconnect the EGR valve position sensor connec-
tor.
(b) Inspect the power output voltage of the EGR valve posi-
tion sensor.
(1) Disconnect the vacuum hose from the EGR valve.
(2) Turn the ignition switch ON.
(3) Connect a voltmeter to terminals VC and E2 of the
ECM, and measure the power source voltage.
Voltage: 4.5 ± 5.5 V

(4) Connect a voltmeter to terminals EGLS and E2 of
the ECM, and measure the power outlet voltage un-
der the following conditions:

Using a MITYVAC (Hand±Held Vacuum
Pump), apply a vacuum (17.3 kPa, 130
mmHg, 5.1 in.Hg) to the EGR valve.
Voltage: 3.2 ± 5.1 V

Release the vacuum from the EGR valve.
Voltage: 0.4 ± 1.6 V
If the voltage is not as specified, replace the EGR valve position
sensor.
(5) Reconnect the vacuum hose to the EGR valve.
3. REMOVE EGR POSITION SENSOR
Remove the 3 nuts and EGR valve position sensor from the
EGR valve.
Torque: 2 N´m (20 kgf´cm, 17 in.´lbf)
4. REINSTALL EGR POSITION SENSOR
Installation is the reverse order of removal.
5. REMOVE EGR VALVE
(a) Remove the EGR pipe.

Remove the 4 nuts, EGR pipe and 2 gaskets.
HINT:
At the time of installation, please refer to the following items.
Install 2 new gaskets.
Torque: 12 N´m (120 kgf´cm, 9 ft´lbf)
(b) Disconnect the EGR gas temperature sensor connector
and clamp.
(c) Remove the EGR valve.
(1) Disconnect the EVAP hose from the EGR valve
hook.
(2) Disconnect the vacuum hose from the EGR valve.
(3) Disconnect the EGR valve position sensor connec-
tor.
(d) Remove the 3 nuts, EGR valve and gasket.
HINT:
At the time of installation, please refer to the following items.
