What does it mean?
C1444 is a Chassis (ABS, traction control, steering) fault code. It indicates: Steering Phase B Circuit Short to Ground .
Symptoms
- Stability and traction control lamps on, systems inactive
- Steering angle reading stuck or clearly wrong on live data
- Reduced or inconsistent electric power steering assist
- Airbag, horn or steering wheel switch faults present at the same time if the clock spring is damaged
- Fault present at key on, without needing a road test
Likely causes
- Chafed phase B wire touching the body or a bracket behind the dash or along the column
- Damaged clock spring with a conductor rubbed through and grounding out
- Water in the column or sensor connector bridging the signal to ground
- Internally shorted sensor channel
- Pinched or trapped harness after airbag, column or dash work
- Crushed terminal or a mis-pinned connector after a previous repair
- Failed module input circuit holding the line low
How to fix it
- Unplug the sensor and measure resistance from the phase B pin to ground; a low reading proves a shorted harness
- If the wire is clear with the sensor unplugged, the short is inside the sensor
- Inspect the harness along the column and behind the dash for chafe points and trapped sections
- Check the clock spring for rubbing marks and moisture
- Verify sensor supply and ground before condemning the sensor
- Repair or reroute the damaged wire, or replace the clock spring or sensor as required
- Clear the code, calibrate the steering angle and confirm the value tracks the wheel smoothly
