MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-768

Check Conditions, Judgement Criteria

• When the fuel consumption calculated from the 

operation time of the injector amounts to 20 litter, 
the diversity of the amount of fuel in tank calcu-
lated from the fuel level sensor is 2 litter or less.

.

OBD-ll DRIVE CYCLE PATTERN
Refer to Diagnostic Function 

− OBD-ll Drive Cycle − 

Procedure 6 

− Other Monitor 

P.13B-7

.

.

TROUBLESHOOTING HINTS (The most likely 
causes for this code to be set are:)

• Fuel level sensor failed.

• Open or shorted fuel level sensor circuit, harness 

damage, or connector damage.

• ECM failed. <M/T>

• PCM failed. <A/T>

DIAGNOSIS

STEP 1. Check fuel gauge.
Q: Is the fuel gauge functioning?

YES : Go to Step 3.
NO :  Go to Step 2.

STEP 2. Check for short circuit to ground between fuel 
level sensor connector D-17 (terminal No. 2) and ECM 
connector C-62 (terminal No. 97) <M/T> or PCM connector 
C-55 (terminal No. 60) <A/T>.

NOTE: Check harness after checking intermediate connectors 
C-90, and C-28. If intermediate connectors are damaged, 
repair or replace them. Refer to GROUP 00E, Harness Con-
nector Inspection 

P.00E-2

. Then go to Step 6.

Q: Is the harness wire in good condition?

YES : Refer to GROUP 54A, Combination Meter 

P.54A-109

.

NO :  Repair it. Then go to Step 6.

STEP 3. Check connector C-62 at ECM <M/T> or connector 
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 4.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection
