C1513

POWER STEERING: POWER STEERING SYSTEM: C1511: Torque Sensor Circuit Malfunction

DTC C1511 - Torque Sensor Circuit Malfunction

DTC C1512 - Torque Sensor Circuit Malfunction

DTC C1513 - Torque Sensor Circuit Malfunction

DESCRIPTION

The torque sensor converts rotation torque input to the steering wheel into an electrical signal and sends it to the ECU. Based on this signal, the ECU detects steering effort.

WIRING DIAGRAM

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (POWER STEERING ECU - TORQUE SENSOR)

(a) Disconnect the C2 ECU connector.
(b) Disconnect the C5 sensor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. INSPECT POWER STEERING GEAR ASSEMBLY (TORQUE SENSOR)

(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:

C -- REPLACE POWER STEERING GEAR ASSEMBLY (W/O VGRS)
B -- REPLACE POWER STEERING GEAR ASSEMBLY (W/ VGRS)
A -- Continue to next step.

3. REPLACE POWER STEERING ECU
(a) Replace the power steering ECU Removal.
NEXT -- Continue to next step.

4. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point Power Steering System.
NEXT -- Continue to next step.

5. RECONFIRM DTC
(a) Check for DTCs Power Steering System.
Result:

NOTE:
If replacing the power steering gear assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point Power Steering System.

C -- REPLACE POWER STEERING GEAR ASSEMBLY (W/O VGRS)
B -- REPLACE POWER STEERING GEAR ASSEMBLY (W/ VGRS)
A -- END
