3. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value ▶
Compression ratio16.5 : 1
Test conditionat normal operating temperature (80˚C)
Compression pressureStandard32 bar
Minimum18 bar
Differential limit between cylindersMaximum 3 bar
The compression pressure test is to check the conditions of internal components (piston, piston
ring, intake and exhaust vale, cylinder head gasket). This test provides current engine operating
status.
Before cranking the engine, make sure that the test wiring, tools and persons are keeping
away from moving components of engine (e.g., belt and cooling fan).
Park the vehicle on the level ground and apply the parking brake.
Do not allow anybody to be in front of the vehicle. -

Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
Remove the air cleaner duct and glow plugs. -

3) Fuel Level Gauge
The fuel level gauge displays the resistance value of the float on the fuel sender in the fuel tank
through a pointer. Note that this vehicle doesn't have a service hole for checking the fuel sender
connector in the fuel tank.
The fuel sender and its connector can be checked and replaced only when the fuel tank is
removed. The power supply and resistance value should be measured at the connector in front of
the fuel sender (refer to wiring diagram).
When the power supply and output resistance are normal, the float operation by fuel level may be
defective; if so, replace the fuel sender.
Low fuel warning lamp comes on when:
The fuel level drops to 9 L or less. The lamp goes off if the fuel level reaches 9.5 L or more.This table shows the tolerance and resistance value changes by fuel level in normal
conditions. Therefore, the differences that can be occurred by the road conditions and fuel
fluctuations are ignored.
