C1444: Steering Phase B Circuit Short to Ground
The C1444 code indicates a short-to-ground fault in the Phase B circuit of the steering system. This manufacturer-specific code is set when the Power Steering Control Module (PSCM) detects that the voltage on the Phase B circuit has dropped below the expected threshold, signaling a direct connection to ground. This fault affects the operation of the steering position sensor or the electric power steering motor, depending on system architecture. Per SAE J2012, this is a chassis/network code for manufacturer-specific steering systems.
1. Commonly Affected Makes
2. Most Common Causes
- Short to ground in the Phase B circuit wiring
- Damaged steering sensor connector or corroded pins
- Faulty steering position sensor (Phase B)
- Issue with the electric power steering (EPAS) motor
3. Symptoms You Will Notice
- Steering wheel feels heavy or difficult to turn
- Steering assist warning light illuminated on dashboard
- Intermittent or complete loss of power steering assist
- Steering wheel may not return to center properly
4. Step-by-Step Diagnosis
Scan for additional codes and verify C1444 is present
Visually inspect the Phase B circuit wiring and connectors for damage, corrosion, or shorts to ground
Test the steering position sensor (Phase B) resistance and voltage per manufacturer specs
Check the PSCM for proper operation and perform a module self-test if available
If wiring and sensor are good, suspect a faulty PSCM or EPAS motor
5. Frequently Asked Questions
Is it safe to drive?▼
No, driving with this code is not recommended as it can cause sudden loss of power steering assist, increasing the risk of an accident. Have the vehicle towed to a repair shop.
How much does it cost to fix?▼
Repair costs typically range from $200 to $1,200 USD, depending on the root cause. A simple wiring repair may cost $200-$400, while replacing the PSCM or EPAS motor can run $800-$1,200.
