STEP 10. Measure the power supply voltage at camshaft
position sensor connector B-106.
(1) Disconnect the connector B-106 and measure at the
harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 3 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 11.
STEP 11. Check harness connector B-17X at MFI relay for
damage.
Q: Is the harness connector in good condition?
YES : Repair harness wire between MFI relay connector
B-17X (terminal No. 4) and camshaft position sensor
connector B-106 (terminal No. 3) because of open
circuit or short circuit to ground. Then go to Step 20.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 20.

STEP 12. Check the continuity at camshaft position sensor
connector B-106.
(1) Disconnect the connector B-106 and measure at the
harness side.
(2) Check for the continuity between terminal No. 1 and
ground.
• Should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 15.
NO : Go to Step 13.
STEP 13. Check harness connector B-22 at PCM 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 20.
