Yes
Step 4
Check the fuel pressure, is it normal?
Refer to
Fuel Pressure Testing Procedure
.
No
Check whether the pipeline is blocked, if
necessary, replace the failed component.
Yes
Step 5
Use the scan tool "Fuel Injector Cleaning and Testing Machine" function, test the performance of the cylinder
fuel injector. Check whether the fuel injectors are normal?
No
Replace damaged fuel injectors.
Yes
is
Step 6
Check whether fuel quality is normal, is the fuel contaminated?
Yes
Replace with good quality fuel.
No
Step 7
Connect scan tool, check the pre-catalytic oxygen sensor signal.
FE02-7002b
(a)
Connect scan tool.
(b)
Start engine and turn on the scan tool.
(c)
Keep the engine speed at 2,500 rpm for more than 2 min to
warm up the engine, until the engine coolant temperature
reaches 80°C (176 ºF).
(d)
Select on the scan tool: Engine / Read Data Flow / Group 1
Oxygen Sensor Voltage 1 (Pre-Catalytic Oxygen Sensors).
(e)
Observe the pre-catalytic oxygen sensor output voltage. The
data flow should fluctuate within 0.1-0.8 V.
(f)
If the voltage data is consistently below 0.45 V (mixture too
lean), carry out the steps as following:
•
Spray proper amount of propane gas into the intake.
•
Observe whether there is a significant change in the pre-
catalytic oxygen sensor voltage data, as the signal
voltage will increase rapidly.
(g)
If the voltage data is always higher than 0.45 V (mixture too
rich), carry out the following steps:
•
Put gear into neutral.
•
Apply hand brake.
•
Press the accelerator pedal so the engine speed
suddenly increases to 4,000 rpm and then quickly release
the accelerator pedal.
•
Repeat the previous steps more than 3 times.
