Power steering pressure sensor voltage
More than 4.9 V
CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on.
5.
Start the engine.
6.
Idle the engine for 5 seconds [A].
7.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].
8.
Read the pending DTC.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
9.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
10.
Input the DTC: P0550, P0552 or P0553.
11.
Check the DTC judgment result.

N/A
Unable to perform DTC judgment
HINT:
If the judgment result shows INCOMPLETE or N/A, perform steps [A] and [B] again.
12.
If no pending DTC is output, perform a universal trip and check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.
13.
INSPECTION PROCEDURE
HINT:
If other DTCs relating to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
Read freeze frame data using the Techstream. Freeze frame data records the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle
was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and
other data from the time the malfunction occurred.

PROCEDURE
1.
CHECK HARNESS AND CONNECTOR (ECM - POWER STEERING OIL PRESSURE
SENSOR)
(a) Disconnect the D74 ECM connector.
(b) Disconnect the D46 power steering oil pressure sensor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:

REPAIR OR REPLACE HARNESS OR CONNECTOR
2.
REPLACE POWER STEERING OIL PRESSURE SENSOR
(a) Replace the power steering oil pressure sensor.
3.
CONFIRM WHETHER DTC OUTPUT RECURS
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON and turn the Techstream on.
(c) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving
Pattern.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) Read the DTCs.

DTC
P0560
System Voltage
DESCRIPTION
The battery supplies electricity to the ECM even when the ignition switch is in the OFF position. This power
allows the ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery
voltage falls below a minimum level, the memory is cleared and the ECM determines that there is a
malfunction in the power supply circuit. When the engine is next started, the ECM illuminates the MIL and
stores the DTC.
DTC NO.
DTC DETECTION CONDITION
TROUBLE AREA

HINT:
If DTC P0560 is stored, the ECM does not store other DTCs or the data stored in the ECM is partly
erased.
