INSPECTION
1. INSPECT AND CLEAN FILTER IN EGR VACUUM MOD-
ULATOR
(a) Remove the cap and filter.
(b) Check the filter for contamination or damage.
(c) Using compressed air, clean the filter.
(d) Install the filter and cap.
HINT:
Install the filter with the coarser surface facing the atmospheric
side (outward).
2. INSTALL VACUUM GAUGE
Using a 3−way connector, connect a vacuum gauge to the hose
between the EGR valve and EGR vacuum modulator.
3. INSPECT SEATING OF EGR VALVE
Start the engine and check that the engine starts and runs at
idle.
4. CONNECT TOYOTA HAND−HELD TESTER OR OBDII
SCAN TOOL
(a) Connect the TOYOTA hand−held tester or OBDII scan
tool to the DLC3.
(b) Please refer to the TOYOTA hand−held tester or OBDII
scan tool operators manual for further details.
5. INSPECT VSV OPERATION WITH COLD ENGINE
(a) The engine coolant temperature should be below 50°C
(122°F).
(b) Check that the vacuum gauge indicates zero at 3,500
rpm.
(c) Check that the EGR pipe is not hot.
6. INSPECT OPERATION OF VSV AND EGR VACUUM
MODULATOR
(a) Select the active test mode on the TOYOTA hand−held
tester (VSV is closed.).

REMOVAL
1. DRAIN ENGINE COOLANT
2. REMOVE EGR PIPE
Remove the 6 nuts, EGR pipe and 2 gaskets.
HINT:
At the time of installation, please refer to the following item.Ins-
tall 2 new gaskets.
Torque:
Nut A: 18.5 N·m (185 kgf·cm, 14 ft·lbf)
Nut B: 8.0 N·m (80 kgf·cm, 71 in.·lbf)
3. REMOVE EGR GAS TEMPERATURE SENSOR
4. REMOVE EGR VALVE
(a) Disconnect these hoses from the EGR valve:
Vacuum hose (from VSV for EGR)
EGR hose (from EGR vacuum modulator)
Water hose (from water bypass pipe)
Water bypass hose (from IAC valve)
(b) Remove the 2 nuts, EGR valve and gasket.
Torque: 18.5 N·m (185 kgf·cm, 14 ft·lbf)
HINT:
Use a new gasket.
At the time of installation, please refer to the following item.
(c) Check for sticking and heavy carbon deposits. If problem
is found, replace the EGR valve.

(c) Using compressed air, clean the filter.
(d) Reinstall the filter and cap.
HINT:
Install the filter with the coarser surface facing out to the atmo-
spheric side.
2. INSTALL VACUUM GAUGE
Using a 3−way connector, connect a vacuum gauge to the hose
between the EGR valve and VSV.
3. INSPECT SEATING OF EGR VALVE
Check that the engine starts and runs at idle.
4. CONNECT TERMINALS TE1 AND E1
Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843−18020
5. INSPECT VSV OPERATION WITH COLD ENGINE
(a) The engine coolant temperature should be below 45°C
(113°F).
(b) Check that the vacuum gauge indicates zero at 2,800
rpm.
(c) Check that the EGR pipe is not hot.
6. INSPECT OPERATION OF VSV AND EGR VACUUM
MODULATOR WITH HOT ENGINE
(a) Warm up the engine to above 80°C (176°F).
(b) Check that the vacuum gauge indicates low vacuum at
2,800 rpm.
(c) Disconnect the vacuum hose from port R of the EGR vac-
uum modulator and connect port R directly to the intake
manifold with another hose.
