What Does U0419 Mean?
The power steering control module (electric or variable assist) is sending corrupted data over the network. This prevents proper coordination between steering effort and vehicle speed or driving conditions.
Safety Warning
Electric power steering assist may fail completely or provide incorrect assist levels, making steering extremely heavy or unpredictable. This creates serious safety hazard especially at low speeds or during emergency maneuvers. Immediate repair required.
Common Causes
35%
Defective steering effort control module with internal component failure
30%
Faulty torque sensor or steering angle sensor providing invalid input data
20%
Damaged wiring or connectors in electric power steering system
10%
CAN bus communication fault affecting steering module data transmission
5%
Low voltage or poor ground affecting steering control module operation
Diagnostic Steps
1
Step 1: Check battery voltage and steering module power supply; verify stable voltage during steering operation
2
Step 2: Inspect steering control module and sensor connectors for corrosion or damage
3
Step 3: Monitor steering torque sensor and angle sensor data using scan tool while turning steering wheel through full range
4
Step 4: Perform steering angle sensor calibration procedure if available; clear codes and retest
5
Step 5: Test CAN bus communication at steering module; replace module if sensors calibrate properly but data remains invalid
Estimated Repair Cost
$250 - $1,600
