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)
