3. INSPECT EGR VALVE
(a) Remove the EGR valve.
(1) Disconnect the 2 vacuum hoses from the EGR
valve.
(2) Remove the 2 bolts, 2 nuts, EGR valve and 2 gas-
kets.
(b) Check the EGR valve for sticking and heavy carbon de-
posits.
If a problem is found, replace the valve.
(c) Reinstall the EGR valve.
(1) Temporarily 2 new gasket and the EGR valve with
the 2 nuts and 2 bolts.
(2) Tighten the nuts.
Torque: 13.3 N´m (136 kgf´cm, 10 ft´lbf)
(3) Tighten the bolts.
Torque: 10 N´m (102 kgf´cm, 7 ft´lbf)
(4) Connect the 2 vacuum hoses to the EGR valve.

(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.
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)
