1.
caution |
Conduct the driving test in a
location where driving
at full acceleration can be done with safety.
Two person should be in the vehicle when the
test
is conducted; the person in the passenger seat
should read the indications shown by the
M.U.T.-III.
|
Set the vehicle to the pre-inspection
condition.
|
|
2.Turn the ignition switch
to "LOOK" (OFF) position, and connect the diagnosis
connector
to the M.U.T.-III. 3.Use the data list function
named "Item No. 6" boost pressure sensor of the M.U.T.-III
to check the supercharging pressure when the engine speed
increases to approximately 3,000 r/min
or more by driving at full acceleration in 2nd.
Standard value: 178.9 - 188.2
kPa 4.If the supercharging pressure
deviates from the standard value, check the following
items for possible cause.
- Malfunction of the waste gate actuator
- Malfunction of the boost pressure sensor
- Leakage of supercharging pressure
- Malfunction of the turbocharger
5.When the indicated supercharging is more than
standard value, supercharging control
may be faulty, therefore check the
followings.
- Disconnection or cracks of the waste gate actuator
rubber hose
- Malfunction of the waste gate actuator
- Malfunction of the waste gate valve
- Malfunction of the manifold absolute pressure
sensor
