C0827: Steering Effort Sensor Stuck
The power steering module has detected that the torque sensor signal does not change despite steering input — the sensor appears stuck. Assist is disabled to avoid uncontrolled steering torque.
What C0827 means
C0827 is a generic OBD-II chassis code in the steering group. In plain English: the part isn’t responding the way the computer expects when it is commanded.
- Check engine light
- Usually off
- Emissions-related
- No
- Limp mode possible

Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Common causes
- 01Sensor mechanically stuckMost likely
- 02Sensor electronics failedPossible
Can I drive with C0827?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Usually lights the ABS, traction or stability warning instead of the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose C0827
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just C0827. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Torque sensor, Power steering module) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Sensor mechanically stuck; sensor electronics failed. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

C0827 FAQ
What does C0827 mean?
C0827 means “Steering Effort Sensor Stuck”. The power steering module has detected that the torque sensor signal does not change despite steering input — the sensor appears stuck. Assist is disabled to avoid uncontrolled steering torque.
Is C0827 serious? Can I keep driving?
We rate C0827 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes C0827?
The most common causes, from most to least likely: Sensor mechanically stuck; Sensor electronics failed. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix C0827?
Typical labor is about $125–$500 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix C0827 myself?
DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will C0827 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
