Standard values
There is no abnormal change in the sensor output signal.
(The pressure sensor signal response changes according
to the engine speed)
Was there no abnormal change in the sensor output signal?
Go to step 5.
Replace the boost pressure sensor.
Perform "After-inspection work" of INFOR-
MATION section.
