(d) If you have no TOYOTA Hand±Held Tester:
Forced driving of the VSV for the EVAP.
(1) Disconnect the VSV connector for the EVAP.
(2) Connect the positive (+) and negative (±) leads from
the battery to the VSV terminals for the EVAP.
(3) Start the engine.
(e) Check the vacuum at idle.
Vacuum:
Maintain at 0.368 ± 19.713 in.Hg (5 ± 268 in.Aq) for over
5 seconds
HINT:
If the vacuum does not change, you can conclude that the hose
connecting the VSV to the service port has come loose or is
blocked, or the VSV is malfunctioning.
(f) TOYOTA Hand±Held Tester:
Conclude forced driving of the VSV for the EVAP.
(1) Stop the engine.
(2) Disconnect the TOYOTA hand±held tester from the
DLC3.
(g) If you have no TOYOTA Hand±Held Tester:
Conclude forced driving of the VSV for the EVAP.
(1) Stop the engine.
(2) Disconnect the positive (+) and negative (±) leads
from the battery from the VSV terminals for the
EVAP.
(3) Connect the VSV connector for the EVAP.
(h) Disconnect the vacuum gauge from the EVAP service
port on the purge line.
(i) Connect a pressure gauge to the EVAP service port on
the purge line.
(j) Check the pressure.
(1) Close off the air drain hose at the marked position
of the canister with a hose clipper or similar instru-
ment.

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.

(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.
Install a new gasket.
Torque: 12 N´m (120 kgf´cm, 9 ft´lbf)
(e) Remove the EGR gas temperature sensor.
Torque: 20 N´m (200 kgf´cm, 14 ft´lbf)
