hose until it reaches the bulge.
When marking is provided on the pipe, insert hose until it cov-
ers half of the marking.

Make sure that support is stable with the use of safety
blocks.
16. Install hooks of lifting chain into engine slingers and tighten
chain so that engine still remains on transmission jacks with-
out being lifted up.
17. Remove engine mount insulator RH.
18. Remove through-bolt of engine mount insulator LH.
19. Remove bolts securing center member at front and rear.
JEM190G
20. Carefully lower transmission jacks in accordance with the low-
ering pace of the hoist, and remove engine and transaxle
assembly from vehicle.
While working, check that no parts of engine assembly
interfere with adjacent parts on the vehicle.
While working, make sure that parts requiring disconnec-
tion are not left connected, and that no parts interfere with
vehicle.
To prevent vehicle from falling down, perform operation
carefully so that the center of gravity of the vehicle will not
shift.
21. Remove center member.
Before starting removal operation, first place the assem-
bly on a level surface and securely support the bottom
surface with wood blocks. Using a hoist, lift engine
slingers, and make sure the assembly is stable.
22. Separate engine and transaxle.
INSTALLATIONNJEM0069S02Install in the reverse order of removal, observing the following:
While installing, be careful to keep mount insulators free of oil
smear and damage.
When parts require specified installation directions/positions,
install by using the identifying marks indicating up or front.
While keeping the mount insulators free of twists or distortions,
start tightening from the through-bolt on the engine mount
insulator LH. This mount is used as the reference position.

ENGINE CONTROL SYSTEM
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from the crankshaft position sensor (POS), the camshaft
position sensor (PHASE) and the mass air flow sensor.
VARIOUS FUEL INJECTION INCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operat-
ing conditions as listed below.

●During warm-up
●When starting the engine
●During acceleration
●Hot-engine operation
●When selector lever is changed from “N” to “D” (A/T models)
●High-load, high-speed operation

●During deceleration
●During high engine speed operation
MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL)
The mixture ratio feedback system provides the best air-fuel mixture ratio for driveability and emission control.
The three way catalyst (manifold) can then better reduce CO, HC and NOx emissions. This system uses
heated oxygen sensor 1 in the exhaust manifold to monitor if the engine operation is rich or lean. The ECM
adjusts the injection pulse width according to the sensor voltage signal. For more information about heated
oxygen sensor 1, refer to EC-155
. This maintains the mixture ratio within the range of stoichiometric (ideal air-
fuel mixture).
This stage is referred to as the closed loop control condition.
Heated oxygen sensor 2 is located downstream of the three way catalyst (manifold). Even if the switching
characteristics of heated oxygen sensor 1 shift, the air-fuel ratio is controlled to stoichiometric by the signal
from heated oxygen sensor 2.
Open Loop Control
The open loop system condition refers to when the ECM detects any of the following conditions. Feedback
control stops in order to maintain stabilized fuel combustion.
●Deceleration and acceleration
●High-load, high-speed operation
●Malfunction of heated oxygen sensor 1 or its circuit
●Insufficient activation of heated oxygen sensor 1 at low engine coolant temperature
●High engine coolant temperature
●During warm-up
●After shifting from “N” to “D” (A/T models)
●When starting the engine
MIXTURE RATIO SELF-LEARNING CONTROL
The mixture ratio feedback control system monitors the mixture ratio signal transmitted from heated oxygen
sensor 1. This feedback signal is then sent to the ECM. The ECM controls the basic mixture ratio as close to
the theoretical mixture ratio as possible. However, the basic mixture ratio is not necessarily controlled as orig-
