Frequently Asked Questions

Can I drive with error code C1280?
Yes, but the power steering may reduce assist, making steering heavy. Drive cautiously to the nearest repair shop. Avoid long trips.
What does EVDS mean?
EVDS stands for Electric Variable Displacement Steering, a type of electric power steering system that adjusts assist based on speed.
How much does it cost to fix error C1280?
Costs vary from $100 for a sensor replacement (DIY) to $500-$1000+ for a steering control module replacement and programming at a dealer.
Will disconnecting the battery clear error code C1280?
Temporarily, yes. But if the underlying issue isn't fixed, the code will return after driving.
Is the encoder sensor the same as the torque sensor?
Often they are combined into one assembly. The encoder detects steering position; the torque sensor measures steering effort. In many vehicles, they are integrated.
