C1512

POWER STEERING: ELECTRONIC POWER STEERING SYSTEM: C1511-C1513: 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.

INSPECTION PROCEDURE

PROCEDURE

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

(a) Disconnect the A67 connector from the power steering ECU assembly.
(b) Disconnect the A71 connector from the torque sensor.
(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 LINK ASSEMBLY (TORQUE SENSOR)

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

NOTICE: If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point Programming and Relearning.

NG -- REPLACE POWER STEERING LINK ASSEMBLY
OK -- Continue to next step.
3. REPLACE POWER STEERING ECU ASSEMBLY
(a) Replace the power steering ECU assembly 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 Programming and Relearning.
NEXT -- Continue to next step.
5. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
