(1)

Replace the knock sensor 2.

To prevent damage to scan tool MB991958, always turn
the ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(2)

Connect scan tool MB991958 to the data link connector.

(3)

Turn the ignition switch to the "ON" position.

(4)

Erase the DTC.

(5)

Start the engine, and leave it idling for more than 2 seconds.
Then stop the engine.

(6)

After completing the test drive, read the DTC.

(7)

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

Q:Is DTC P0333 set?

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.

NO:

The inspection is complete.

STEP 4. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

(1)

Turn the ignition switch to the "ON" position.

(2)

Start the engine, and leave it idling for more than 2 seconds.
Then stop the engine.

(3)

After completing the test drive, read the DTC.

(4)

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

Q:Is DTC P0333 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

CIRCUIT OPERATION

｠

The crankshaft position sensor power is supplied
from the ECM (terminal No. 9).

｠

Terminal No. 1 of the crankshaft position sensor is
grounded with ECM (terminal No. 24).

｠

A 5-volt voltage is applied on the crankshaft position
sensor output terminal (terminal No. 3) from the
ECM (terminal No. 8). The crankshaft position
sensor generates a pulse signal when the output
terminal is opened and grounded.

TECHNICAL DESCRIPTION

｠

The crankshaft position sensor detects the crank
angle (position) of each cylinder, and converts that
data to pulse signals, then which are input to the
ECM.

｠

When the engine is running, the crankshaft position
sensor outputs a pulse signal.

｠

The ECM checks whether pulse signal is input while
the engine is cranking.

DESCRIPTIONS OF MONITOR METHODS

｠

Crankshaft position sensor signal does not change.

｠

Crankshaft position sensor signal is not normal
pattern.
