.

Check Condition, Judgement Criterion

• When the fuel consumption calculated from the 

operation time of the injector amounts to 20 liters 
(5.2 gal) <FWD> or 30 liters (7.8 gal) <AWD>, the 
diversity of the amount of fuel in tank calculated 
from the fuel level sensor is 2 liters (0.5 gal) or 
less.

.

OBD-II DRIVE CYCLE PATTERN

None.

.

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

• Combination meters assembly failed.

• Fuel level sensor failed.

• ECM failed.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-558

STEP 1. Using scan tool MB991958, read the diagnostic 
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2066 set?

YES : Go to Step 2.
NO :  Go to Step 4.

STEP 2. Check fuel gauge.
Q: Is the fuel gauge functioning?

YES : Go to Step 3.
NO :  Refer to GROUP 54A, Combination Meter 

− Trouble 

Symptom Chart 

P.54A-69

.

STEP 3. Check the trouble symptoms.
Check that the fuel gauge operates correctly.
Q: Does the fuel gauge operate correctly?

YES : It can be assumed that this malfunction is intermittent. 

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

− How to 

Cope with Intermittent Malfunctions 

P.00-15

.

NO :  Replace the ECM. When the ECM is replaced, 

register the ID code. Refer to GROUP 42B, Diagnosis 
− ID Codes Registration Judgment Table <Vehicles 

with KOS>

STEP 4. Check the fuel pump module.
Check to see if the fuel pump module is normal. Refer to 
GROUP 54A, Combination Meter 

− On-vehicle Service − Fuel 

Level Sensor Check 

P.54A-107

.

Q:  Is the fuel pump module normal?

YES : Go to Step 5.
NO :  Replace the fuel pump module. Then go to Step 6.

STEP 5. Check the trouble symptoms.
Check that the fuel gauge operates correctly.
Q: Does the fuel gauge operate correctly?

YES : It can be assumed that this malfunction is intermittent. 

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

. Then go to Step 6.

STEP 6. Check the trouble symptoms.
Check that the fuel gauge operates correctly.
Q: Does the fuel gauge operate correctly?

YES : The inspection is complete.
NO :  Retry the troubleshooting.

DTC P0462: Fuel Level Sensor <FWD> or Fuel Level Sensor (main) <AWD> Circuit Low Input

.

TECHNICAL DESCRIPTION

• The fuel level sensor converts the rest of the fuel 

to a voltage and sends it to the combination 
meter.

• The combination meter sends the data regarding 

the rest of the fuel to the ECM.

• The ECM checks whether this data is within a 

specified range.

.

DESCRIPTIONS OF MONITOR METHODS

A short circuit is detected while monitoring the fuel 
level sensor output.

.

MONITOR EXECUTION

Continuous

.
