The pressure difference between the fuel pressure and
the intake manifold is about 3.8 bars during the full load.

5. Fuel Pressure (approx. 3.8 bars)
6. Intake Manifold Negative Pressure (0 bar)

The spring chamber (9) is connected to the intake man-
ifold with the vacuum hose at the intake pipe connection
(7). The negative pressure generated in the intake man-
ifold activates the diaphragm, and thus the fuel pressure
gets reduced to the rate of the operating extent of the
diaphragm by the intake manifold’s negative pressure.
YAA1F510
Consequently, the fuel pressure in the fuel distributor
changes by the intake manifold’s negative pressure, and
the injector ’s fuel pressure gets reduced independentlyto the throttle valve’s position. Thus, the fuel injection
volume can only be determined according to the injec-
tor’s injecting duration.
The pressure difference between the fuel pressure and
the intake manifold is approx. 3.2 bars during idling.

Measuring Procedure
1. Warm the engine up to normal operating tempera-
ture.
2. Remove the spark plugs.
3. Place the diagram sheet to compression pressure
tester.
4. Connect the adaptor to compression pressure tester
and install it into the spark plug hole.
5. Crank the engine approx. eight revolutions by using
the start motor.6. Compare the measurements of compression pres-
sure tester with the specifications.
7. Measure the compression pressure of the other cylin-
ders in the same way.
8. If measured value is not within the specifications, per-
form the cylinder pressure leakage test.
Notice
DDischarge the combustion residues in the cylinders
before testing the compression pressure.
DApply the parking brake before cranking the engine.

CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless other -
wise noted.
