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).

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)
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.

(3)
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.
