What C0529 means
C0529 is set when the steering angle sensor module has no valid zero point. Stellantis documents it as C0529-00 on the 2023 Dodge Hornet and the 2023–2024 Alfa Romeo Tonale: if the wheel was turned without assist between key-off and key-on, the calibration was lost and the MIL came on, going out again after a lock-to-lock turn; an EPS software update fixes it (TSB 08-148-23, 08-163-23). For the 2022–2023 Ram ProMaster, an internal note asks for sensor initialisation by turning lock to lock with the engine running, or via wiTECH, after battery disconnection and before any steering gear replacement. Saab and Mitsubishi likewise require a straight-ahead calibration after alignment or sensor replacement.
C0529 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.1 to 0.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0529
- Malfunction indicator lamp on (Stellantis)
- ESC warning lamp on, stability control limited until calibrated
- Lamp goes out after turning the wheel from lock to lock
Common causes of C0529
- Most likelyCalibration lost after battery disconnection or steering while switched off
- PossibleInitialisation skipped after steering gear, sensor or alignment work
- PossibleEPS software losing the calibration (Stellantis 2023–2024)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0529 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 C0529
What does C0529 mean?
C0529 means "Steering Angle Sensor Module Missing Calibration". C0529 is set when the steering angle sensor module has no valid zero point. It is a generic code, so it means the same on every make.
Is it safe to drive with C0529?
Drive gently and only to a workshop. With C0529 the car can go into limp mode (reduced power) to protect itself.
Will C0529 fail an emissions test?
C0529 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 C0529 to fix?
Difficulty: easy. A typical repair takes 0.1 to 0.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C0529 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
