MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI)

13A-473

STEP 3. Retest the system.
(1) Carry out a test drive with the drive cycle pattern. Refer to

Diagnostic Function

− OBD-II Drive Cycle − Procedure 6 −

Other Monitor

P.13A-4

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0340 set?

YES : Replace the PCM. Then go to Step 18.
NO : It can be assumed that this malfunction is intermittent.

Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points

P.00-7

.

STEP 4. Check connector A-42 at camshaft position
sensor for damage.
Q: Is the connector in good condition?

YES : Go to Step 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 18.

STEP 5. Measure the sensor supply voltage at camshaft
position sensor connector A-42.
(1) Disconnect the connector A-42 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 4.8 and 5.2 volts

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.8 and 5.2 volts?

YES : Go to Step 10.
NO : Go to Step 6.

STEP 6. Measure the sensor supply voltage at PCM
connector C-90 by backprobing.
(1) Do not disconnect the PCM connector C-90.
(2) Disconnect the camshaft position sensor connector A-42.
(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between terminal No. 56 and ground

by backprobing.

• Voltage should be between 4.8 and 5.2 volts.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.8 and 5.2 volts?

YES : Go to Step 7.
NO : Go to Step 8.

STEP 7. Check connector C-90 at PCM for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between camshaft position

sensor connector A-42 (terminal No. 2) and PCM
connector C-90 (terminal No. 56) because of open
circuit. Then go to Step 18.

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

Connector Inspection

P.00E-2

. Then go to Step 18.
