Dynamic test for backleak of injector ▶
Warm up the engine so that the engine
coolant temperature be over 80℃ and star
the engine again.
Disconnect the injector return hose and
cover the openings with caps shaped
screw (included in the special tool).. 1.
2.
Connect the hose of the container for
measuring backleak to the return nipple of
the injector.
Start the engine again and let the engine
idle for 30 seconds.
Perform backleak test of fuel system with a
diagnostic device after 30 seconds. 3.
4.
5.
This test consists of 4 cycles, and the engine
rpm reaches 3,500 rpm for 18 seconds in each
cycle.
Check the amount of backleak collected
into the container and confirm that it is
within the specified range. 6.
Specification38 ml or less

The engine ECU calculates the accelerator pedal based on the input signals from various sensors,
and controls the overall operation of the vehicle.
The ECU receives the signals from various sensor through data line, and performs effective air-fuel
ratio control based on these signals.
The crankshaft speed (position) sensor measures the engine speed, and the camshaft speed
(position) sensor determines the order of injections, and the ECU detects the amount of the
accelerator pedal depressed (driver's will) by receiving the electrical signals from the accelerator
pedal sensor.
The mass air flow sensor detects the volume of intake air and sends the value to the ECU.
The major function of the ECU is controlling air-fuel ratio to reduce the emission level (EGR valve
control) by detecting instantaneous air flow change with the signals from the mass air flow sensor.
Also, the ECU uses the signals from the coolant temperature & air temperature sensors, booster
pressure sensor, atmospheric pressure sensor to: a) determine injection starting point and set
value for pilot injection, and b) deal with various operations and variable conditions.

2. INSPECTION
Problem Possible Cause Action
Coolant level is
too low- Leak from the radiator
- Leak from the coolant auxiliary tank
- Leak from the heater core- Change the radiator
- Change the coolant auxiliary tank
- Change the heater
- Leak from the coolant hose
connections
- Damaged coolant hose- Reconnect the hose or replace
the clamp
- Change the hose
- Leak from the water pump gasket
- Leak from the water pump internal
seal- Change the gasket
- Change the water pump
- Leak from the water inlet cap
- Leak from the thermostat housing- Change the water inlet cap
gasket
- Change the thermostat sealing
- Incorrect tightening torque of the
cylinder head bolts
- Damaged cylinder head gasket- Tighten the bolts to the specified
torque
- Change the cylinder head gasket
Coolant
temperature is
too high- Coolant leakage (Coolant level is low)
- Improper coolant mixture ratio
- Kinked coolant hose- Add coolant
- Check the coolant concentration
(Anti-freeze)
- Repair or replace the hose
- Defective thermostat
- Defective water pump
- Defective radiator
- Defective coolant auxiliary tank or
tank cap- Change the thermostat
- Change the water pump
- Change the radiator
- Change the coolant auxiliary tank
or tank cap
- Cracks on the cylinder block or
cylinder head
- Clogged coolant passages in the
cylinder block or cylinder head- Change cylinder block or cylinder
head
- Clean the coolant passage
- Clogged radiator core - Clean the radiator core
- Improper operation of cooling fan - Replace the cooling fan or repair
the related circuit
- Defective temperature sensor or
faulty wiring- Replace the sensor or repair the
related wiring
Coolant
temperature is
too low- Thermostat is stuck open - Change the thermostat
- Improper operation of cooling fan - Replace the cooling fan or repair
the related circuit
- Defective temperature sensor or
faulty wiring- Replace the sensor or repair the
related wiring
