steering
Pontiac g6 2007, electric power steering has quit. I've done some research. no recalls on 07. 04-06 and 08-10 do have. says to replace column on the 08. doesn't make sense to me. if there's a short it should be able to repair it. any insight on this problem?

RE: steering
If there's a short then there's probably a blown fuse somewhere. Not being familiar with this car in particular I can only venture a guess so here we go....

The electric PS system has an input, which means the motion from the wheel is needed to make the pump do it's thing. The next part is the output, meaning the electric pump itself. The two are connected via a small computer. Soooo, that all said... there could be no input (steering column problem or sensor?) or there could be no power to the pump (blown fuse, bad wire, or connection?) or there could be a malfunction of that small computer / control module.

Hope that puts you in better light of the situation.

RE: steering
I would like to add that a Full Function Scanner may be able to point you in the right direction. If there are sensors, the scanner should be able to pull data as to what is and isn't working. There also may be codes stored that will help. Sometimes the price of a scan is way less than trying to figure it out the old fashioned way.

Thanks for using the forum,

RE: steering
power steering control module The PSCM uses a combination of steering shaft torque sensor input, vehicle speed, calculated system temperature and steering tuning to determine the amount of steering assist. When the steering wheel is turned, the PSCM uses signal voltage from the steering shaft torque sensor to detect the amount of torque and steering direction being applied to the steering column shaft and then command the proper amount of current to the power steering motor. The PSCM receives a vehicle speed message from the PCM via the serial data circuit. At low speeds more assist is provided for easy turning during parking maneuvers. At high speeds, less assist is provided for improved road feel and directional stability. The PSCM nor the power steering motor are designed to handle 65 amps continuously. If the power steering system is exposed to excessive amounts of static steering conditions, the PSCM will go into a protection mode to avoid thermal damage to the power steering components. In this mode the PSCM will limit the amount of current commanded to the power steering motor which reduces system temperature and steering assist levels. The PSCM must also be setup with the correct steering tuning which are different in relation to the vehicles powertrain configuration, sedan, coupe, tire and wheel size etc.. The PSCM has the ability to detect malfunctions within the power steering system. Any malfunction detected will cause the DIC to display the POWER STEERING warning message and/or the service vehicle soon indicator.

Some customers of 2005-2006 model year Chevrolet Malibu, Malibu Maxx; Pontiac G6 vehicles, and 2008 model year Chevrolet Malibu, Malibu Maxx; Pontiac G6; and Saturn AURA vehicles equipped with electric power steering may experience a loss of power steering assist caused by electrical input signals within the steering column assembly. If the power steering assist is lost, a chime will be heard and the Driver Information Center will display a "Power Steering" warning message. On some vehicles, the Service Vehicle Soon light will also illuminate. The vehicle can still be steered in a safe manner but will require greater driver effort at low vehicle speeds or when stopped.

are you receiving on the dic display power steering along with the check engine light?
