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 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with 
WCM>

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 

P.00E-2

. 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 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with

P.42C-10

. 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.
