STEP 6. Measure the sensor supply voltage at PCM
connector B-22 by using power plant ECU check harness
special tool MB991923.
(1) Disconnect the all PCM connectors and connect power
plant ECU check harness special tool MB991923 between
the separated connectors.
(2) Disconnect the camshaft position sensor connector B-106.
(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between terminal No. 104 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 : Go to Step 7.
NO : Go to Step 8.
STEP 7. Check harness connector B-22 at PCM for
damage.
Q: Is the harness connector in good condition?
YES : Repair harness wire between camshaft position
sensor connector B-106 (terminal No. 2) and PCM
connector B-22 (terminal No. 104) because of open
circuit. Then go to Step 20.
NO : Repair or replace it. Refer to GROUP 00E, Harness
. Then go to Step 20.
