• Steering wheel warning light on
• Loss of power steering assist
• Electronic Stability Control (ESC) malfunction
• Faulty Steering Angle Sensor Module
• Wiring issues such as open or short circuits
• Faulty Powertrain Control Module (PCM)
PCM: Powertrain Control Module
SASM: Steering Angle Sensor Module
• U0121
• U0428
This code means that your car's computer is having trouble talking to a part of the car that helps with steering. It's like when your phone can't connect to the internet.
U0220 indicates a loss of communication with the steering angle sensor module.
The U0220 code is triggered when the vehicle's main computer (the Powertrain Control Module, or PCM) cannot communicate with the Steering Angle Sensor Module (SASM). This module is responsible for detecting the steering wheel position and sending this information to other systems like the Electronic Stability Control (ESC).
• Check for other related trouble codes.
• Inspect the wiring and connectors for damage or corrosion.
• Test the Steering Angle Sensor Module for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty Steering Angle Sensor Module.
• Reprogram or replace the PCM if necessary.
• OBD-II Scanner
• Multimeter
• Wiring diagram

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect wiring and connectors.
• Keep the steering system well-maintained.
• Avoid modifications that could affect electrical systems.
Communication Error
• Do not ignore the warning light; get it checked promptly.
• Avoid driving in challenging conditions until repaired.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer as some components might be covered under warranty.
This code has become more common with the increased use of electronic steering systems in modern vehicles.
Moderate – It should be addressed soon, but the vehicle can still be driven with caution.
Driving with a malfunctioning steering system can be dangerous. Ensure repairs are conducted by a qualified professional.
• Vehicle in a safe, stationary position.
• Ignition turned on without starting the engine.
The Steering Angle Sensor Module is typically located near the steering column or integrated into the steering wheel assembly.
Q: Can I drive with a U0220 code?
A: While you can drive with this code, it's not recommended as it affects the steering system's safety features.
Q: How do I reset the U0220 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
