(4) Connect a voltmeter to terminals EGLS and E2 of
the ECM, and measure the power outlet voltage un-
der the following conditions:
S
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
S
Release the vacuum from the EGR valve.
Voltage: 0.4 – 1.6 V
(5) Reconnect the vacuum hose to the EGR valve.
REMOVE EGR POSITION SENSOR
Torque: 2 N·m (20 kgf·cm, 17 in.·lbf)
REINSTALL EGR POSITION SENSOR
Installation is the reverse order of removal.
REMOVE EGR VALVE
Remove the EGR pipe.
S
Remove the 4 nuts, EGR pipe and 2 gaskets.
Torque: 12 N·m (120 kgf·cm, 9 ft·lbf)
Disconnect the EGR gas temperature sensor connector
and clamp.
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.
Remove the 3 nuts, EGR valve and gasket.
Torque: 12 N·m (120 kgf·cm, 9 ft·lbf)
Remove the EGR gas temperature sensor.
Torque: 20 N·m (200 kgf·cm, 14 ft·lbf)
