Circuit Diagram










DTC Confirmation Procedure

Upon completion of initial check, turn steering wheel in both directions (fully when stopped and turning while driving).

Troubleshooting

1.
Was "P/S System Check" performed?
YES -
Go to Step 2.
NO -
Go to P/S System Check P/S System Check.

2. Torque sensor circuit check

Confirm that the ignition mode of keyless push start system is in "OFF".
Disconnect P/S control module (rotation angle sensor/torque sensor) and torque sensor connectors.
Check for proper connection to P/S control module and torque sensor terminals.
Check "A1", "A2", "A3", "A4" and "A5" circuits between P/S control module and torque sensor for broken wire and short to ground.

Are they in good condition?
YES -
Go to Step 2.
NO -
Repair or replace defective wire harness and recheck DTC.

3. Torque sensor power supply circuit check

Connect P/S control module (rotation angle sensor/torque sensor) and torque sensor connectors.
Push engine switch to change ignition mode to "ON".
Check voltage between "1" terminal of P/S control module (rotation angle sensor/torque sensor) connector and ground.

Is voltage 8.6 - 10.2 V?
YES -
Go to Step 3.
NO -
Substitute a known-good P/S control module and recheck DTC. Service and Repair

4. Torque sensor ground circuit check

Check voltage between "1" and "8" terminals of P/S control module (rotation angle sensor/torque sensor) connector.

Is voltage 8.6 - 10.2 V?
YES -
Go to Step 4.
NO -
Substitute a known-good P/S control module and recheck DTC. Service and Repair

5. Torque sensor check

Check torque sensor. Torque Sensor Inspection

Is it in good condition?
YES -
Substitute a known-good P/S control module. Service and Repair
NO -
Replace torque sensor (steering gear case assembly). Removal and Installation
