CHECK
(1) Connect a hand vacuum pump to nipple (A) of the
solenoid.
Check airtightness by applying a vacuum with voltag e
applied directly from the ‘battery to
evaporative
emission ventilation solenoid. and
(3) Measure the resistance between the terminals of the
solenoid.

EXHAUST GAS RECIRCULATION
GENERAL INFORMATION
The exhaust gas recirculation (EG system lowers
the nitrogen oxide
emission level. When the
air/fuel mixture combustion temperature is high,
a large quantity of nitrogen oxides is gener-
ated in the combustion Therefore, this
system recirculates part of emission gas from the
exhaust port of the cylinder head to the combustion
OPERATION
When the engine coolant is low, when
the engine is at idle or when a wide open throttle
operation is performed, the EGR valve is kept
closed, achieving no EGR.
The manifold differential pressure sensor is locate d
in the intake manifold plenum. This sensor detects
variations in the manifold pressure when
the EGR solenoid is momentarily operated. If the
manifold negative pressure the EGR sys-
tem is normal.

The EGR flow rate is controlled by the EGR valve

In normal vehicle operation performed after warm-
ing up of the engine, the EGR valve is opened
to carry out EGR.
The ECM uses this to check the operation of the, EGR system. If a problem is found, the check en-’
indicator light illuminates to warn
the driver that a problem has occurred.

DRIVE SHAFT REMOVAL
(1) a pry bar between the transaxle case and the drive
shaft, and then pry the drive shaft from the transa xle.
Caution
1.Use a pry bar to remove drive shaft from the
assembly, or the T.J. assembly may be
damaged.
2.Do not insert the bar too far, or the oil’
be damaged.
(2) Use the special tool to cover the transaxle cas e not to’
let foreign materials get into the transaxle case.
DRIVE SHAFT WITH INNER SHAFT
DISCONNECTION
Lightly tap the center -bearing bracket plastic
hammer or similar tool “to remove the inner shaft f rom
the transaxle.
,
(2) Suspend the removed drive shaft with inner shaf t with
wire so that there are no sharp bends in any of the joints.
(3) Use the special tool to cover the transaxle case not to
let foreign materials get into the transaxle case.
R E L E A S E
Remove the clutch release cylinder without disconne cting
the line, and suspend to a nearby parts with a wire,
etc.
