C0608Steering Wheel Angle Sensor Circuit Performance
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- C0608 covers a steering angle signal that is electrically in range but cannot be trusted: it jumps, drifts, freezes or disagrees with what yaw rate, lateral acceleration and wheel speeds imply. The Kelsey-Hayes patent rejects a centre offset that moves by more than about 15° after a dropout, and Bosch builds plausibility checks of the individual measuring channels into its GMR sensor. HELLA reminds workshops to zero the sensor after alignment or steering work, since a wrong zero point disturbs stability control. FMVSS 126 defines ESC as a system that monitors driver steering inputs, so the module switches ESC off once that input is doubtful. No maker publishes C0608; related checks are C0528, C052A and C05B2.
- What you may notice
- ESC lamp on, sometimes only after a few turns or straight driving
- Unexpected ESC braking interventions
- Steering angle not zero with the wheels pointing straight
- Likely causes
- LikelySensor not zeroed after wheel alignment, steering or column repair
- PossibleSteering wheel fitted off centre or toe out of adjustment
- PossibleWorn or faulty sensor giving jumping or frozen values
- RareBrief signal dropouts from a loose connector
- Repair
- Medium · Usually a job for a workshop.Typical cost: €30 – €500
