8. Check the CO contents and the HC contents at
idle.
Standard value
CO contents: 0.5 % or less
HC contents: 100 ppm or less
9. If there is a deviation from the standard value,
check the following items:
•
Diagnosis output
•
Fuel pressure
•
Injector
•
Ignition coil, spark plug
•
EGR control system
•
Evaporative emission control system
•
Compression pressure
NOTE: Replace the three way catalyst when the
CO and HC contents are not within the standard
value, even though the result of the inspection is
normal on all items.
10.Turn the ignition switch to the "LOCK" (OFF)
position and then remove the MUT-II/III.
COMPRESSION PRESSURE CHECK
M1111002600636
1. Before inspection, set the vehicle to the
pre-inspection condition.
2. Remove all of the ignition coils and spark plugs.
3. Disconnect the crank angle sensor connector.
NOTE: Doing this will prevent the
engine-ECU<M/T> or engine-A/T-ECU<A/T> from
carrying out ignition and fuel injection.
CAUTION
•
Keep away from the spark plug hole when
cranking.
•
If compression is measured with water, oil,
fuel, etc., that has come from cracks inside
the cylinder, these materials will become
heated and will gush out from the spark plug
hole, which is dangerous.
4. Cover the spark plug hole with a shop towel etc.,
and after the engine has been cranked, check that
no foreign material is adhering to the shop towel.
5. Set compression gauge to one of the spark plug
holes.
6. Crank the engine with the throttle valve fully open
and measure the compression pressure.
Standard value (at engine speed of 200
r/min):
1,560 kPa
Limit (at engine speed of 200 r/min):
Minimum 1130 kPa
7. Measure the compression pressure for all the
cylinders, and check that the pressure differences
of the cylinders are below the limit.
Limit: Maximum 98 kPa
8. If there is a cylinder with compression or a
compression difference that is outside the limit,
pour a small amount of engine oil through the
spark plug hole, and repeat the operations in
steps from (5) to (7).
(1) If the compression increases after oil is added,
the cause of the malfunction is a worn or
damaged piston ring and/or cylinder inner
surface.
(2) If the compression dose not rise after oil is
added, the cause is a burnt or defective valve
seat, or pressure is leaking from the gasket.
9. Connect the crank angle sensor connector.
10.Install the spark plugs and tighten to the specified
torque.
Tightening torque: 25

4 N

m
11.Install the ignition coils.
12.Use the MUT-II/III to erase the diagnosis codes.
NOTE: This will erase the diagnosis code
resulting from the crank angle sensor connector
being disconnected.

MANIFOLD VACUUM CHECK
M1111002700569
1. Before inspection, set the vehicle to the
pre-inspection condition.
2. Turn the ignition switch to the "LOCK" (OFF)
position and then connect the MUT-II/III to the
diagnosis connector.
3. Disconnect the ventilation hose from the PCV
valve, and connect a vacuum gauge to the
ventilation hose.
4. Plug the PCV valve.
5. Start the engine and check that idle speed is
within the standard valve.
Standard value
: 680
±
100 r/min <M/T>
: 750
±
100 r/min <A/T>
6. Check the intake manifold vacuum.
Limit: Minimum 60 kPa
7. Turn off the ignition switch.
8. Remove the vacuum gauge and then connect the
ventilation hose.
9. Turn the ignition switch to the "LOCK" (OFF)
position and then remove the MUT-II/III.

REMOVAL SERVICE POINT
<<A>> DRIVE BELT REMOVAL
The following operations will be needed due to the
introduction of the serpentine drive system with the
drive belt auto-tensioner.
1. Securely insert the spindle handle or ratchet
handle with a 12.7 mm insertion angle into the jig
hole of the auto-tensioner.
2. Rotate the auto-tensioner anti-clockwise and align
hole A with hole B.
CAUTION
To reuse the drive belt, draw an arrow indicating
the rotating direction (clockwise) on the back of
the belt using chalk, etc.
3. Insert an L-shaped hexagon wrench, etc. into the
hole to fix and then remove the drive belt.
