WARNING:
Hot engines and oil can cause severe burns. Be careful not to burn yourself during removal/installation of each component.
Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”..
1. Verify that the battery is fully charged..
Recharge it if necessary..
2. Warm up the engine to the normal operating temperature.
3. Perform “Fuel Line Safety Procedures”..
4. Remove the following parts.
a. Plug hole plate..
b. Ignition coil/ion sensors..
c. Spark plugs..
d. Fuel pump relay
e. Fuel injector relay
5. Measure the compression pressure using the following procedure.
a. Press a compression gauge into the spark plug hole.
b. Fully depress the accelerator pedal.
c. Crank the engine and measure the compression pressure.
Standard: 827 kPa {8.43 kgf/cm2, 120 psi} [300 rpm]
Minimum: 661 kPa {6.74 kgf/cm2, 95.9 psi} [300 rpm]
Maximum difference between cylinders: 140 kPa {1.43 kgf/cm2, 20.3 psi}
NOTE:
Because the SKYACTIV-G 2.0 retards the intake valve closing timing, compression pressure is low.
d. Perform Steps (1) to (3) for all cylinders.
e. If the measured value is less than the minimum value, or there is a cylinder whose compression value varies from that of other cylinders by 140 kPa {1.43 kgf/cm2, 20.3 psi}
or more, add a small amount of engine oil through the spark plug hole. Then measure the compression pressure and perform the respective operations for the following cases.
If the pressure increases by adding the engine oil, the piston ring or the cylinder surface is worn, or they are damaged. Perform overhaul servicing.
If the pressure does not increase, valve seizure, valve attachment malfunction, or pressure leakage from the cylinder head gasket might be occurring. Perform overhaul servicing.
f. If the measured value is high, it is possible that there is an error in the electric variable valve timing system.
6. Remove the compression gauge.
7. Install the following parts.
a. Fuel injector relay
b. Fuel pump relay
c. Spark plugs..
d. Ignition coil/ion sensors..
e. Plug hole plate..
Variable Tumble Shutter Valve Switch Inspection [Mzr 2.0, Mzr 2.5]
Voltage Inspection
NOTE:
The variable tumble shutter valve switch cannot be removed as a single unit.
When replacing the variable tumble shutter valve switch, replace it together
with the intake manifold as a single unit.
1. Connect the M-MDS to the DLC–2.
2. Switch the ig ...
Variance Between Actual Road Conditions and Displayed Image
Some variance occurs between the actual road and the displayed road. Such
variance in
distance perspective could lead to an accident. Note the following conditions
that may cause
a variance in distance perspective.
