EMISSION CONTROL
ENGINE AND EMISSION CONTROL17-11
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.

M1173001700193
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
At idle Vacuum is maintained.

Engine condition Normal condition
At idle Vacuum is maintained.
3,000 r/min (within 3
minutes after engine
starts)Vacuum will leak.
