(1)
Disconnect the connector B-102 and B-10 measure at the
harness side.
(2)
Measure the resistance between connector B-102 (terminal
No. 2) and connector B-10 (terminal No. 58).
⦆
Should be less than 2 ohms.

⦆
Not continuity.
Q:Is the harness wire in good condition?
YES:
Then go to Step 8.
NO:
Repair it. Then go to Step 8.
STEP 7. 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 P0552 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 8.
NO:
The inspection is complete.

STEP 8. 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 P0552 set?
YES:
Retry the troubleshooting.
NO:
The inspection is complete.

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.
