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, Chassis Electrical - Combination

Meters Assembly - Symptom Chart P.13Ab-8.

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, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 6.

DIAGNOSTIC TROUBLE CODE PROCEDURES

STEP 4. Check the fuel pump module.
Check to see if the fuel pump module is normal. Refer to GROUP
54A,  Chassis  Electrical  -  Combination  Meters  Assembly  and
Vehicle Speed Sensor - On-Vehicle Service - Fuel Level Sensor
Check P.13Ab-8.

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 - 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, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. 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 Circuit Low Input

M11310100235USA0000010000

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.
