Mitsubishi Outlander XL. Manual - part 245

 

CIRCUIT OPERATION

｠

A  5-volt  power  supply  is  applied  on  the  throttle
position sensor (main) power terminal (terminal No.
5) from the ECM (terminal No. 12).
The ground terminal (terminal No. 3) is grounded
with ECM (terminal No. 13).

TECHNICAL DESCRIPTION

｠

The throttle position sensor (main) outputs voltage
which  corresponds  to  the  throttle  valve  opening
angle.

｠

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

DESCRIPTIONS OF MONITOR METHODS

Throttle position sensor (main) 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

｠

MB991658: Test Harness

STEP 1. Using scan tool MB991958, check data list item 13:
Throttle Position Sensor (main).

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)

Detach the intake air hose at the throttle body.

(4)

Disconnect the connector of the throttle position sensor.

(5)

Use test harness special tool (MB991658) to connect only
terminals No. 3, No. 4, No. 5, and No. 6.

(6)

Set scan tool MB991958 to the data reading mode for item
13, Throttle Position Sensor (main).

｠

Output voltage should be between 0.3 and 0.7 volt when
the throttle valve is fully closed with your finger.

｠

Output voltage should be between 4.0 volts or more when
the throttle valve is fully open with your finger.

(7)

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 harness connector B-08 at the throttle
position sensor and harness connector B-10 at the 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. Measure the sensor supply voltage at throttle
position sensor harness side connector B-08.

(1)

Disconnect the connector B-08 and measure at the harness
side.

(2)

Turn the ignition switch to the "ON" position.

Measure the voltage between terminal No. 5 and ground.

｠

Voltage should be between 4.9 and 5.1 volts.

(4)

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

Q:Is the measured voltage between 4.9 and 5.1 volts?

YES:

 Go to Step 5.

NO:

 Go to Step 4.

STEP 4. Check for open circuit to ground or harness
damage between the throttle position sensor connector
B-08 and the ECM connector B-10.

(1)

Disconnect the throttle position sensor connector B-08 and
the ECM connector B-10.
