1. Disconnect the vacuum hose (red stripe) from
throttle body and connect it to a hand vacuum
pump.
2. Plug the nipple from which the vacuum hose was
removed.
3. When the engine is cold or hot, apply a vacuum of
53 kPa, and check the condition of the vacuum.
When engine is cold
(Engine coolant temperature: 40°C or less)
When engine is hot
(Engine coolant temperature: 80°C or higher)
PURGE PORT VACUUM CHECKM1173001500177
1. Disconnect the vacuum hose (red stripe) from the
throttle body and connect a hand vacuum pump to
the nipple.
2. Plug the vacuum hose (red stripe).3. Start the engine.
4. Check that a fairly constant negative pressure is
generated regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.

NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid
valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the
solenoid valve (refer to the illustration at left). Engine condition Normal condition

5. Replace the gasket, and tighten to the specified
torque.

EGR PORT VACUUM CHECK <4G1>M1173002900167
1. Disconnect the vacuum hose (Green stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (Green stripe).
3. Start the engine and check that, after raising the
engine speed by racing the engine, purge vacuum
raises according to engine speed.
NOTE: If there is a problem with change in
vacuum, the throttle body purge port may be
clogged and require cleaning.
EGR PORT VACUUM CHECK <4G6>M1173002900156
1. Disconnect the vacuum hose (White stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (White stripe).
3. Start the engine.
4. Check that a fairly constant negative is generated
regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.

NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid
valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the
solenoid valve (refer to the illustration at left).
4. Check air tightness by applying a vacuum with
voltage applied directly from the battery to the
EGR control solenoid valve and without applying
voltage.
