No. Testing Procedures
e Project
• Use meter direct
measurement battery
voltage
Power and
• Use diagnosis tool
1
voltage
detection of battery
voltage
• Use fuel pressure
gauge connected in
series between the
injector and the
pressure regulating
valve
• Main switch ON but
not start engine
Fuel
2
• Check fuel pressure
pressure
• Start engine (Idle)
• Check change of fuel
pressure
• Throttle several
rotation
• Check to the change
of fuel pressure again
• The spark plug
removed from the
cylinder head but the
Ignition
power lines still ring
3
• Start engines or use
state
for the diagnosis tool of
output view spark plug
ignition conditions
• Diagnosis tool to
Engine
4
detect the use of
vacuum
• The injector removed
Injection from the throttle body

Test items Determine benchmarks
• Battery • Battery voltage = 10 V
above
• Open the main • Open main switch but not
switch but not to start:
start the engine of Pressure = 250 kPa (stable
pressure value)
• Pressure in Idle • Idle state:
• Rotating throttle,
Pressure = 300+/-6 kPa
(Beating situation from top
situation of
to bottom)
pressure changes
• Rotating throttle moment:
Pressure=300+/-6kPa(sligh
tly beating)
• Spark plug • Specifications: NGK-CR7H
• Ignition conditions:
specifications
• Whether the
With traditional engines
spark plug ignition found ways
• Spark plug sparks
whether it is
normal strength
• Manifold pressure • Manifold pressure = 32~38
of diagnosis tool kPa
• Open the main • Not started, Injector not
switch but did not leaking fuel
• In started, the injection
start engine the
injection situation
state must show fan shape
Fault reasons
• Battery electricity
• Battery connector
loose
• Harness circuit
opening
• ECU coupler not
connected properly
• Fuel not enough
• Fuel pump relay
fault
• Fuel pump fault
• Injector fault
• ECU fault
• Spark plug fault
• Roll over sensor
fault
• ECU No. 12 pin fault
• Ignition coil fault
• Crankshaft position
sensor fault
• Valve clearance
abnormal
• Intake system leak
• Fuel pump relay
fault
• Fuel pump fault
• Injector fault
