(3)

Check for the continuity between connector B-121 (terminal
No. 2) and ground.

｠

Not continuity.

Q:Is the harness wire in good condition?

YES:

Go to Step 6.

NO:

Repair it. Then go to Step 6.

STEP 6. Using scan tool MB991958, check actuator test item
21: Intake manifold tuning Solenoid.

(1)

Turn the ignition switch to the "ON" position.

(2)

Set scan tool MB991958 to the actuator test mode for item
21, Intake manifold tuning solenoid.

｠

An operation sound should be heard and vibration should
be felt when the intake manifold tuning solenoid is
operated.

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the solenoid operating properly?

YES:

The inspection is complete.

NO:

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.

CIRCUIT OPERATION

｠

A battery positive voltage is applied to the engine
oil pressure switch output terminal (terminal No. 1)
from the ECM (terminal No. 36) via the resistor in
the ECM.

TECHNICAL DESCRIPTION

｠

The engine oil pressure switch converts the
existence of a engine oil pressure into a high/low
voltage, and inputs it into the ECM.

13Ab-612

MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>

DIAGNOSTIC TROUBLE CODE PROCEDURES

｠

When the engine oil control valve operates, the
engine oil pressure in the MIVEC system rises. The
engine oil pressure switch opens, thus interrupting
the application of the battery positive voltage. As a
result, the output voltage of the engine oil pressure
switch will fluctuate between 0 and 12 volts.

｠

The ECM checks whether the engine oil pressure
switch "OFF" or "ON" during driving.

DESCRIPTIONS OF MONITOR METHODS

Compare engine oil pressure switch status with
engine operating condition.
