STEP 11. Measure the power supply voltage at crankshaft 
position sensor harness side connector A-43.
(1) Disconnect the connector A-43 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 13.
NO :  Go to Step 12.

STEP 12. Check connector C-59 at MFI relay for damage.
Q: Is the connector in good condition?

YES : Check connector C-14 at intermediate connector for 

damage, and repair or replace as required. Refer to 
GROUP 00E, Harness Connector Inspection 

P.00E-2

. If intermediate connector is in good 

condition, repair harness wire between MFI relay 
connector C-59 (terminal No. 1) and crankshaft 
position sensor connector A-43 (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 

P.00E-2

. Then go to Step 20.

STEP 13. Check for continuity at crankshaft position 
sensor harness side connector A-43.
(1) Disconnect the connector A-43 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 14.
NO :  Repair harness wire between crankshaft position 

sensor connector A-43 (terminal No. 1) and ground 
because of open circuit or harness damage. Then go 
to Step 20.

STEP 14. Check connector C-59 at the MFI relay for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 15.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 20.
