Mitsubishi Outlander XL. Manual - part 228

13Ab-132, DTC P0108 - Manifold Absolute Pressure Circuit
High Input P.13Ab-138.

STEP 3. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

(1)

Turn the ignition switch to the "ON" position.

(2)

Erase the DTC.

(3)

Start the engine.

(4)

Turn the ignition switch to "LOCK" (OFF) position and then
wait 2 seconds.

(5)

Turn the ignition switch to the "ON" position.

(6)

Set scan tool MB991958, read the DTC.

(7)

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

Q:Is DTC P0069 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 4.

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

(1)

Turn the ignition switch to the "ON" position.

(2)

Erase the DTC.

(3)

Start the engine.

(4)

Turn the ignition switch to "LOCK" (OFF) position and then
wait 2 seconds.

(5)

Turn the ignition switch to the "ON" position.

(6)

Set scan tool MB991958, read the DTC.

(7)

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

Q:Is DTC P0069 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.

CIRCUIT OPERATION

｠

The mass airflow sensor power is supplied from the
MFI  relay  (terminal  No.  4),  and  the  ground  is
provided on the ECM (terminal No. 88).

｠

A voltage that is according to the mass airflow rate
is sent to the ECM (terminal No. 87) from the mass
airflow sensor output terminal (terminal No. 3).

TECHNICAL DESCRIPTION

｠

While the engine is running, the mass airflow sensor
outputs  voltage  which  corresponds  to  the  mass
airflow rate.

｠

The ECM checks whether the voltage output by the
mass airflow sensor while the engine is running is
within a specified range.

DESCRIPTIONS OF MONITOR METHODS

Compare  load  value  with  mass  airflow  sensor
output voltage.
