COMPONENT LOCATION
EXHAUST GAS RECIRCULATION (EGR)
CONTROL SYSTEM CHECK
1. Disconnect the vacuum hose (green stripe) from the EGR
control solenoid valve, and then connect a hand vacuum
pump via the three-way terminal.
2. When the engine is hot or cold, check the condition of
vacuum by racing the engine.
When engine is cold
(Engine coolant temperature: 20_C or less)
Throttle valveNormal vacuum condition
Open quicklyNo vacuum will generate
(the same as barometric pressure.)
When engine is hot
(Engine coolant temperature: 80_C or higher)
Throttle valveNormal vacuum condition
Open quicklyIt will momentarily rise over 13 kPa
3. Disconnect the three-way terminal.
4. Connect the hand vacuum pump to the vacuum hose
(green stripe).
5. Check whether the engine stalls or the idling is unstable
when a vacuum of 27 kPa or higher is applied during
idling.

EGR VALVE CHECK
1. Remove the EGR valve and inspect for sticking, carbon
deposits, etc. If found, clean with a suitable solvent so
that the valve seats correctly.
2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the vacuum
is maintained.
4. Apply a vacuum and check the passage of air by blowing
through one side of the EGR passage.
VacuumPassage of air
5.3 kPa or lessAir is not blown out
27 kPa or moreAir is blown out
5. Replace the gasket, and tighten to the specified torque.
Tightening torque: 20±2 N·m
EGR PORT VACUUM CHECK
1. Disconnect the vacuum hose (White stripe) from the
throttle body EGR vacuum nipple and connect a hand
vacuum pump to the nipple.
2. Start the engine and check vacuum remains fairly constant
after racing the engine.
NOTE
If the vacuum fluctuates, the throttle body EGR port may
be clogged and need cleaning.

EGR CONTROL SOLENOID VALVE CHECK
NOTE
When disconnecting the vacuum hose, always make a mark
so that it can be reconnected at original position.
1. Disconnect the vacuum hose (yellow stripe, green stripe,
white stripe) from the solenoid valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to the nipple to which
the green-striped vacuum hose was connected.
4. Check airtightness by applying a vacuum with voltage
applied directly from the battery to the EGR control
solenoid valve and without applying voltage.

5. Measure the resistance between the terminals of the
solenoid valve.

quarter turn to clockwise in the position as shown in the
illustration.
6. Connect the connector to the clutch pedal position switch.
7. Check that the engine starts when the clutch is released.

TROUBLESHOOTING
BASIC TROUBLESHOOTING CONDITIONS
Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points.
NOTE
Before starting the troubleshooting procedure, make sure that the following items have been checked
okay.
DIs the appropriate steering wheel installed at the center of the steering column shaft correctly?
DAre the tire, wheel size, specifications, air pressure, balance, and wear state normal?
DIs the wheel alignment normal?
DHas the engine, suspension, etc. been remodeled in such a way that it will affect the ACD and AYC
systems?
DIAGNOSIS FUNCTION
READING DIAGNOSIS CODE
Read a diagnosis code by the MUT-IIor ACD mode indicator
lamp. (Refer to GROUP 00 - How to Use Troubleshooting/
Inspection Service Points.)
NOTE
Connect the MUT-IIto the diagnosis connector (16-pin).
ERASING DIAGNOSIS CODES
When using the MUT-II
Connect the MUT-IIto the diagnosis connector (16-pin) and
erase the diagnosis code.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
