Mitsubishi Outlander XL. Manual - part 378

CIRCUIT OPERATION

｠

A 5-volt power supply is applied on the accelerator
pedal position sensor (sub) power terminal
(terminal No. 4) from the ECM (terminal No. 78).
The ground terminal (terminal No. 5) is grounded
with ECM (terminal No. 79).

TECHNICAL DESCRIPTION

｠

The accelerator pedal position sensor (sub) outputs
voltage which corresponds to the accelerator pedal
depression.

｠

The ECM checks whether the voltage is within a
specified range.

DESCRIPTIONS OF MONITOR METHODS

Accelerator pedal position sensor (sub) output
voltage is out of specified range.

DIAGNOSIS

Required Special Tools:

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: V.C.I.

｠

MB991827: USB Cable

｠

MB991910: Main Harness A

STEP 1. Check harness connector C-123 at accelerator
pedal position sensor and harness connector B-11 at ECM
for damage.

Q:Is the harness connector in good condition?

YES:

Go to Step 2.

NO:

Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection P.00E-2. Then go to Step 4.

STEP 2. Check for open circuit or short circuit to ground or
harness damage between accelerator pedal position sensor
connector C-123 and ECM connector B-11.

Data link

connector

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
12, Accelerator Pedal Position Sensor (sub).

｠

Output voltage is between 0.4 and 0.6 volts when foot is
released from accelerator pedal.

｠

Output voltage is 2.0 volts or higher when accelerator
pedal is fully depressed.

(4)

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

Q:Is the sensor operating properly?

YES:

Go to Step 4.

NO:

Replace the accelerator pedal position sensor. Then

go to Step 4.

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

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

(3)

Read the DTC again.

(4)

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

Q:Is DTC P2127 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.

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.
