YES:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 8.

NO:

 The Inspection is complete.

STEP 8. Test the OBD-II Drive Cycle.

(1)

Carry  out  test  drive  with  the  drive  cycle  pattern.  Refer  to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  21  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1020 set?

YES:

 Retry the trouble shooting.

CIRCUIT OPERATION

｠

The engine oil control valve power is supplied from
the MFI relay (terminal No. 2).

｠

The ECM controls ground engine oil control valve
by turning the power transistor in the ECM "ON" and
"OFF".

TECHNICAL DESCRIPTION

｠

The  engine  oil  pressure  switches  the  cams  to
operate  the  MIVEC  system  in  the  low-speed  or
high-speed  mode  in  accordance  with  the  signals
from the ECM.

DESCRIPTIONS OF MONITOR METHODS

Circuit voltage stays low when solenoid status is off.

MONITOR EXECUTION

Continuous
