STEP 4. Measure the sensor supply voltage at ECM
connector B-10 by using power plant ECU check harness
special tool MB992110.
(1) Disconnect all ECM connectors. Connect the power plant

ECU check harness special tool MB992110 between the
separated connectors.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 9 and ground.

• Voltage should be battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)

present?
YES : Repair harness wire between the crankshaft position

sensor connector B-119 (terminal No. 1) and the ECM
connector B-10 (terminal No. 9) because of open
circuit or harness damage. Then go to Step 9.

NO : Go to Step 5.

STEP 5. Check for short circuit to ground between the
crankshaft position sensor connector B-119 and the ECM
connector B-10.
(1) Disconnect the crankshaft position sensor connector B-119

and the ECM connector B-10.

(2) Check for the crankshaft position sensor connector B-119

(terminal No. 1) and ground.

• Not continuity.

Q: Is the harness wire in good condition?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Codes Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

− ID

Codes Registration Judgment Table <Vehicles with
WCM>

P.42C-10

. Then go to step 9.

NO : Repair it. Refer to GROUP 00E, Harness Connector

Inspection

P.00E-2

. Then go to Step 9.

STEP 6. Check for open circuit and short circuit to ground
between the crankshaft position sensor connector B-119
and the ECM connector B-10.
(1) Disconnect the crankshaft position sensor connector B-119

and the ECM connector B-10.

(2) Measure the resistance between the crankshaft sensor

connector B-119 and the ECM connector B-10.

• Should be less than 2 ohms.

a. Connector B-119 (terminal No. 3) and Connector B-10

(terminal No. 8).

b. Connector B-119 (terminal No. 2) and Connector B-10

(terminal No. 24).

(3) Check for the crankshaft position sensor connector B-119

(terminal No. 3) and ground.

• Not continuity.

Q: Is the harness wire in good condition?

YES : Go to Step 7.
NO : Repair it. Then go to Step 9.

STEP 7. Using the oscilloscope, check the crankshaft
position sensor.
(1) Disconnect the crankshaft position sensor connector B-119,

and connect the test harness special tool (MB991709)
between the separated connectors.

(2) Connect the oscilloscope probe to crankshaft position

sensor connector terminal No. 3.
NOTE: When measuring with the ECM side connector, dis-
connect all ECM connectors. Connect the check harness
special tool (MB992110) between the separated connec-
tors. then connector the oscilloscope probe to the check
harness connector terminal No. 8.

(3) Start the engine and run at idle.

(4) Check the waveform.

• The waveform should show a pattern similar to the illus-

tration.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the waveform normal?

YES : Go to Step 8.
NO : Repair the crankshaft position sensor. Then go to

Step 9.

STEP 8. Check the trouble symptoms.
(1) Carry out a test drive with the drive cycle pattern. Refer to

Diagnostic Function

− OBD-II Drive Cycle − Pattern 22

P.13B-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0335 set?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Codes Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

− ID

Codes Registration Judgment Table <Vehicles with
WCM>

P.42C-10

. Then go to Step 9.

NO : It can be assumed that this malfunction is intermittent.

Refer to GROUP 00, How to Use
