C1512
POWER STEERING: ELECTRONIC 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 (BETWEEN POWER STEERING ECU ASSEMBLY AND TORQUE SENSOR)
(a) Disconnect the P42 connector from the power steering ECU assembly.
(b) Disconnect the P44 connector from the torque sensor.
(c) Measure the resistance according to the value(s) in the table below.
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.
Resistance:
NOTE: If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate 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 VALUE 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.
(b) Is DTC C1511, C1512 or C1513 output?
OK:
DTC is not output.
NOTE: If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate torque sensor zero point Programming and Relearning.
NG -- REPLACE POWER STEERING LINK ASSEMBLY
OK -- END
