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
ECM 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 5.

(1)

Disconnect the connector B-102 and B-10 measure at the
harness side.

(2)

Measure the resistance between connector B-102 (terminal
No. 1) and connector B-10 (terminal No. 59).

｠

Should be less than 2 ohms.

Q:Is the measured resistance less than 2 ohms?

YES:

Go to Step 4.

NO:

Repair it. Then Go to Step 5.

STEP 4. Replace the power steering pressure sensor.

(1)

Replace the power steering pressure sensor.

(2)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.

(3)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0553 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 5.

NO:

The inspection is complete.

STEP 5. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0553 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.
