Causes

Faulty steering angle sensor (internal electronics degraded)
Damaged, corroded or loose sensor connector or wiring harness
Poor or intermittent reference voltage or ground to the sensor
Steering column mechanical binding, excessive play, or damaged sensor tone ring
Sensor not calibrated or calibration lost after repairs or battery disconnect
Faulty ABS/ESC/steering control module that reads sensor data

Symptoms

ABS, ESC/Traction Control or warning lamp illuminated
Stability control functions disabled or behaving erratically
Steering angle live value incorrect or jumping when wheel is steady
Stored diagnostic trouble codes related to steering/ABS/traction
Possible vehicle handling complaints under braking or cornering

What to check

Read freeze frame and all related codes with a capable scan tool; note conditions when code set
Visually inspect steering angle sensor connector and wiring for damage, corrosion, or pin push-out
Check for recent repairs to steering column, wheel, or battery that would require SAS calibration
Verify vehicle is at rest and steering wheel centered for baseline checks
Backprobe sensor power, reference and ground with ignition ON (engine OFF) and compare to expected values
Monitor steering angle live data while slowly rotating the steering wheel to observe smooth response

Signal parameters

Typical sensor supply/reference: near battery voltage or 5 V reference (varies by manufacturer); measure with key ON engine OFF
Typical output: analog voltage that varies with wheel position (common range ~0.5–4.5 V) or digital CAN/LIN messages for absolute angle
At centered steering wheel the absolute output is often mid-range (≈2.5 V) for analog sensors; angle should change smoothly with steering input
Ground continuity: low resistance to chassis ground (
When digital, expect steady CAN/LIN messages at known interval with valid angle values; loss or invalid data indicates communication or module issue

Diagnostic algorithm

Connect a full-function scan tool. Record the C2007 code, related codes (ABS, ESC), and freeze frame data. Check live steering angle value and compare to wheel position.
Perform a visual inspection of sensor and harness at the steering column. Repair any obvious wiring damage, broken pins, or corroded connectors.
With ignition ON (engine OFF), backprobe the sensor connector: verify proper reference/supply voltage and ground. If voltages are out of range, trace and repair supply/ground circuits.
Observe live sensor signal (voltage or CAN/LIN data) while slowly turning the steering wheel. Look for non-linear jumps, dropouts, or no change. Wiggle the harness to check for intermittent faults.
If analog output is incorrect but supply and ground are good, replace the steering angle sensor. If digital messages are missing, verify CAN/LIN network integrity and module operation.
After sensor replacement or wiring repair, perform required steering angle sensor calibration/adaptation with a scan tool per manufacturer procedure (vehicle wheels must be straight and vehicle level as specified).
Clear codes and test drive under the conditions that originally set the code to confirm repair. Recheck for stored or returning codes.
If fault persists after sensor and wiring checks and calibration, investigate the ABS/ESC/steering control module and bus communication for faults or intermittent failures.

Likely causes

Steering angle sensor failure or out-of-spec output
Connector corrosion, pin damage or wiring open/short near the column
Improper or missing steering angle sensor calibration/adaptation
Bad ground or reference voltage to sensor
Intermittent fault caused by steering column movement/wire chafe

Fault status

⚠️ Status

Steering Angle Sensor Circuit — Range/Performance: control module detected the steering angle sensor output is outside expected range or not performing correctly. May disable stability/traction systems until resolved.
