DIAGNOSTIC TROUBLE CODE PROCEDURES

STEP 1. Using scan tool MB991958, check data list item 53:
Fuel Tank Temperature Sensor.

To prevent damage to scan tool MB991958, always turn the
ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting 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)

Set scan tool MB991958 to the data reading mode for item
53, Fuel Tank Temperature Sensor.

｠

Approximately  the  same  as  the  ambient  air  temperature
when the engine is cooled.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the sensor operating properly?

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:

 Go to Step 2.

STEP 2. Check the harness connector D-20 at the fuel tank
temperature sensor and harness connector B-11 at ECM for
damage.

Q:Is the harness connector in good condition?

YES:

 Go to Step 3.

NO:

 Repair it. Refer to GROUP 00E, Harness Connector

Inspection P.00E-2. Then go to Step 6.

STEP 3. Check the fuel tank temperature sensor.

(1)

Disconnect the fuel tank temperature sensor connector D-20.

ZK603321AA00

(2)

Measure the resistance between terminal No. 1 and No. 3 of
the fuel tank temperature sensor.

Standard value: 0.5 - 12.0 kΩ

Q:Is the measured resistance between 0.5 and 12.0 kΩ?

YES:

 Go to Step 4.

NO:

 Replace the fuel tank temperature sensor. Then go to

Step 6.

STEP 4. Check for short circuit to ground between the fuel
temperature sensor connector D-20 and the ECM connector
B-11.

(1)

Disconnect the fuel temperature sensor connector D-20 and
the ECM connector B-11.

(2)

Check  for  the  continuity  between  the  temperature  sensor
connector D-20 (terminal No. 3) and ground.

｠

Not continuity.

Q:Is the harness wire in good condition?

YES:

 Go to Step 5.

NO:

 Check harness connector C-129 at Intermediate

connector for damage, and repair as required. Refer to
GROUP 00E, Harness Connector Inspection P.00E-2. If the
Intermediate connector C-129 is good condition, repair
harness wire between the temperature sensor connector
D-20 (terminal No. 3) and the ECM connector B-11 (terminal
No.115) because of open circuit. Then go to Step 6.

STEP 5. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  22  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0182 set?

YES:

 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.

NO:

 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.

STEP 6. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  24  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0182 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.
