My 2005 lsj has a abs light on all the time and I can’t clear it with a code scanner. I also lose power steering after a while of driving and the time from when I start my car to when I lose power steering is different everyday. Also seems like the longer the car sits the longer I have power steering. I know the car has eps but I don’t know what the problem is.

Does your dash cluster do funny things simultaneously with losing power steering?

My gas gauge is a little off and I will gain or lose estimated km until empty or it won’t move at all for a couple minutes at a time. Other then that nothing but the “power steering” that pops up on the dash

Just wondering because I had a weird issue where my power steering will go out momentarily when I first start the car after an autocross run. It is also accompanied by the gas, tach, and speedo not reading. I've never tracked it down but I think I have a funky ground somewhere. Mine always comes back after about 30 seconds though.

What codes are set. You could have a bad eps motor, controller, or torque sensor.

I have a left rear wheel speed sensor for an abs code

Kolt

Can your scanner access power steering codes? That one isn't going to cause power steering issues.

05misfire

No all my scanner does is abs srs and for engine lights

Kolt

Need to find someone who has one that can pull codes from the power steering module. With those I can give you a direction you will need to go. Otherwise its just a guessing game.

I got it scanned and it’s a steering angle position sensor

Kolt

Do you have the code number

05misfire

Yeah, c0475

Kolt

That is a power steering motor circuit code. If that is the only code then you either need the Power steering motor or a steering column assembly. You only need the column if there is a lot of slack in the gears for the column. Unless your column rattles really bad I would get the motor first and see how it does. Also you need to inspect the motor wire terminals on the module and make sure they are not burnt.

I had a gm mechanic look at it and he said it’s inside the steering column

Kolt

Did he say what part was failed specifically, because inside the column is a torque sensor. If that is really the only code that is set a torque sensor wont fix it just to let you know if that is what he said it needs. I am a master ase GM tech and I know these vehicle inside and out. Id like to know more in detail on what he said if you can. Just trying to look out for ya.

05misfire

No he didn’t say specifically but I think I’m going to get it diagnosed to see what the problem is and thanks anyways

05misfire

I had a dealer look at it and they said it was the motor so can I just replace the motor myself and that’s it.

Kolt, what question do I ask of a mechanic, if they can "pull codes from a PS module"? I presume your standard AutoZone scanner can't do this. Short of taking my Cobalt to a Chevy dealer - how do I find the guy who can diagnose?

Thanks
