｠

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.

MONITOR EXECUTION
