C0608 code meaning
Steering Wheel Angle Sensor Circuit Performance
What C0608 means
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.
C0608 at a glance

- Limp modePossible

- Typical labor0.3 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of C0608
- 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
Common causes of C0608
- Most 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
- Less likelyBrief signal dropouts from a loose connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 08 | The exact fault in that area. |
What to do next
- Note C0608 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0608
What does C0608 mean?
C0608 means "Steering Wheel Angle Sensor Circuit Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with C0608?
Drive gently and only to a workshop. With C0608 the car can go into limp mode (reduced power) to protect itself.
Will C0608 fail an emissions test?
C0608 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0608 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will C0608 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
