U0131 on Pontiac
Lost Communication with Power Steering Module
U0131 on Pontiac vehicles indicates lost communication with power steering module. Au7o has documented this code across 1 Pontiac model — most commonly on G6. 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.
Common Causes of U0131
- •Loss of power or ground to the power steering module
- •Open or shorted CAN bus wiring to the module
- •Corroded or loose connector at the steering module
- •Blown fuse feeding the power steering system
- •Failed power steering control module
- •Other module or wiring fault disrupting the data bus
- •Software/configuration mismatch after a repair

- Sudden loss of electric power steering (EPS) assist2005-2009
NHTSA campaigns 14V153000 and 15V064000 together cover affected 2005-2009 Pontiac G6 vehicles for sudden loss of electric power-steering assist. The remedy depends on model year and build window and can involve the torque sensor, EPS motor/controller or applicable bulletin. The campaign-wide 1,373,177 figure is not a G6-only count, and exact sources do not support calling this the single most-complained-about defect or assigning a 70,000-100,000-mile onset.
