Mitsubishi Outlander XL. Manual - part 345

CIRCUIT OPERATION

｠

A 5-volt voltage is supplied to the power steering
pressure  sensor  power  terminal  (terminal  No.  3)
from the ECM (terminal No. 43).

｠

The ground terminal (terminal No. 1) is grounded
with the ECM (terminal No. 59).

｠

A voltage that is proportional to the power steering
pressure is sent to the ECM (terminal No. 58) from
the power steering pressure sensor output terminal
(terminal No. 2).

TECHNICAL DESCRIPTION

｠

The  power  steering  pressure  sensor  outputs  a
voltage  which  corresponds  to  the  power  steering
pressure.

｠

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

DESCRIPTIONS OF MONITOR METHODS
Power steering pressure sensor 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. Using scan tool MB991958, check data list item 24:
Power Steering Pressure sensor.

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)

Start the engine and run at idle.

(3)

Set scan tool MB991958 to the data reading mode for item
24, Power Steering Pressure sensor.

｠

If  the  steering  wheel  is  not  turned  while  idling,  voltage
should be between 400 and 1,000 mV.

｠

If the steering wheel is turned while idling, voltage should
be between 3,000 and 4,000 mV.

(4)

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-102 at the power
steering pressure sensor and harness connector B-10 at
PCM for damage.

Q:Is the harness connector in good condition?

YES:

 Go to Step 3.

NO:

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

Connector Inspection P.00E-2. Then go to Step 8.

STEP 3. Measure the power supply voltage at power
steering pressure sensor connector B-102.

(1)

Disconnect  the  connector  B-102  measure  at  the  harness
side.

(2)

Turn the ignition switch to the "ON" position.

(3)

Measure the voltage between terminal No. 3 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 6.

NO:

 Go to Step 4.
