Steering wheel angle

sensor

C1061 (5061)

Defective steering wheel

angle sensor

Pressure sensor

C1051 (5051)

Defective input sensor

Cause

- Abnormal signals from pressure sensor

- Defective pressure sensor or harness

Action

- Check the pressure sensor connector

Cause

- Internally defective steering wheel angle sensor

- Abnormal signals from steering wheel angle sensor

- Short circuit between supplying voltage output and ground

- Abnormal signal voltage from steering wheel angle sensor

- Poor installation of steering wheel angle sensor and abnormal signal

Action

- Check the supplying voltage: (Specified voltage: 9 ~ 16 V)

- Check the output voltage: Check voltage between ESP unit terminals with ignition ON

ST1 voltage check: between ESP unit terminal No. 5 and ground (Specified voltage:

1.3 ~ 4.1V)

ST2 voltage check: between ESP unit terminal No. 2 and ground (Specified voltage:

1.3 ~ 4.1V)

STN voltage check: between ESP unit terminal No.12 and ground (Specified voltage:

1.3 ~ 4.1V)
