Frequently asked questions
What does U0131 mean on a Pontiac?
U0131 stands for "Lost Communication with Power Steering Module." This is a network communication code meaning the vehicle's computers have lost communication with the power steering control module over the data bus (CAN). Modern cars link control modules so they can share data, and this code sets when other modules stop receiving expected messages from the power steering unit. The most common result is loss or reduction of power-assisted steering, making the wheel feel heavy, along with a warning light. It generally points to a wiring/connector or power problem at the steering module, a bus fault, or a failed module rather than a mechanical steering issue. On Pontiac it is documented across 1 model: G6.
What are the most common causes of U0131?
