STEP 7. Measure the sensor supply voltage at ECM
connector B-10 by using power plant ECU check harness
special tool MB992110.
(1) Disconnect the all ECM connectors. Connect the power
plant ECU check harness special tool MB992110 between
the separated connectors.
(2) Disconnect the intake camshaft position sensor connector
B-123.
(3) Turn the ignition switch to the "ON" position.
(4) Measure the voltage between terminal No. 14 and ground.
• Voltage should be between 4.9 and 5.1 volts.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.9 and 5.1 volts?
YES : Repair harness wire between intake camshaft
position sensor connector B-123 (terminal No. 3) and
ECM connector B-10 (terminal No. 14) because of
open circuit. Then go to Step 19.
NO : Go to Step 8.
STEP 8. Check for short circuit to ground between intake
camshaft position sensor connector B-123 (terminal No. 3)
and ECM connector B-10 (terminal No. 14).
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 Code Registration Judgment Table <Vehicles
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
. Then go to Step 19.
NO : Repair it. Then go to Step 19.

STEP 9. Measure the power supply voltage at intake
camshaft position sensor connector B-123.
(1) Disconnect the connector B-123 and measure at the
harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 1 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 : Go to Step 12.
NO : Go to Step 10.
STEP 10. Check harness connector B-10 at ECM for
damage.
Q: Is the harness connector in good condition?
YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 19.
STEP 11. Check for open circuit and short circuit to ground
between intake camshaft position sensor connector B-123
(terminal No. 1) and ECM connector B-10 (terminal No. 9).
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 Code Registration Judgment Table <Vehicles
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
. Then go to Step 19.
NO : Repair it. Then go to Step 19.
STEP 12. Check the continuity at intake camshaft position
sensor connector B-123.
(1) Disconnect the connector B-123 and measure at the
harness side.
(2) Check for the continuity between terminal No. 2 and
ground.
• Continuity (2 ohms or less).
Q: Does continuity exist?
YES : Go to Step 15.
NO : Go to Step 13.

STEP 13. Check harness connector B-10 at ECM for
damage.
Q: Is the harness connector in good condition?
YES : Go to Step 14.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 19.
STEP 14. Check for open circuit and harness damage
between intake camshaft position sensor connector B-123
(terminal No. 2) and ECM connector B-10 (terminal No. 30).
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 Code Registration Judgment Table <Vehicles
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
. Then go to Step 19.
NO : Repair it. Then go to Step 19.
STEP 15. Check harness connector B-10 at ECM for
damage.
