Mitsubishi Outlander XL. Manual - part 280

YES:

 Go to Step 6.

NO:

 Repair it. Then go to Step 8.

STEP 6. Check the left bank injector.

(1)

Disconnect  the  left  bank  injector  connector  B-115,  B-116,
B-120.

Injector side
connector

1 2

(2)

Measure  the  resistance  between  each  injector  side
connector terminal No. 1 and No. 2.

Standard value: 10.5 - 13.5 Ω [at 20°C (68°F)]

Q:Is the measured resistance between 10.5 and 13.5 ohms

[at 20°C (68°F)]?

YES:

 Go to Step 7.

NO:

 Replace the injector. Then go to Step 8.

STEP 7. 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 P0175 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 8.

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 8. 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  22  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0175 output?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.

CIRCUIT OPERATION

｠

5-volt voltage is applied to the fuel tank temperature
sensor  output  terminal  (terminal  No.  3)  from  the
ECM (terminal No. 115) via the resistor in the ECM.

｠

The  fuel  tank  temperature  sensor  output  voltage
increases  when  the  resistance  increases  and
decreases  when  the  resistance  decreases.  The
ground terminal (terminal No. 1) is grounded to the
vehicle body.

TECHNICAL DESCRIPTION

｠

The fuel tank temperature sensor converts the fuel
tank temperature to a voltage.

｠

The ECM detects the fuel tank temperature with this
output voltage.

DESCRIPTIONS OF MONITOR METHODS
Fuel tank temperature at engine start is higher than
engine  coolant  temperature  at  engine  start  by
specified value when engine is cold start condition.
