MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-549

STEP 6. Measure the sensor supply voltage at crankshaft 
position sensor intermediate harness side connector 
B-119.

(1) Disconnect the connector B-119 and measure at the 

harness side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 2 and ground.

• Voltage should be between 4.9 and 5.1 volts.

(4) 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 11.
NO :  Go to Step 7.

STEP 7. 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 crankshaft position sensor intermediate 

connector B-119.

(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between terminal No. 103 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 8.
NO :  Go to Step 9.

STEP 8. Check harness connector B-22 at PCM for 
damage.

Q: Is the harness connector in good condition?

YES : Repair harness wire between crankshaft position 

sensor intermediate connector B-119 (terminal No. 2) 
and PCM connector B-22 (terminal No. 103) because 
of open circuit. Then go to Step 22.

NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 22.
